Renault 18TS not start
Make: RENAULT (RENAULT) 18TS cars
Symptom: Car pushed, pulled the car can not be started. After examination, the carburetor is normal, center and sub-cylinder car key replacement high-voltage power lines were arcing. The carburetor has tempered signs, exhaust pipe smoke exhaust and tempering regularly.
Troubleshooting: judging from the above symptoms, it seems that the ignition disorder, but distributor, sub-cylinder power lines were not moving off. After examination, the ignition timing is also normal, valve and no wiring. Demolition pick up spark plug, see the electrodes are wet gasoline, replacement, or can not start the car. After checking the cylinder pressure are within the specified range. When checking sub-cylinder high-voltage flash over again, and found that flash interval was uneven. Taking into account the carburetor has tempered signs, it is suspected distributor cap problems. After high pressure on the distributor cap testing found high voltage electrical channeling place between the lid bmw carsoft 6.5 center jack. It is concluded that the problems lies in the distributor cap. Because the distributor cap firing order and regularity appears inevitable confusion when high pressure channeling electricity, and therefore can not start the engine and carburetor will appear tempering phenomenon. Now replace the distributor cap, start the engine quickly, the fault disappears.

Toyota Reiz car door remote control failure
Approximately 148,000 km mileage 2008 Toyota Reiz sedan. Users reflect: remote control car door can not be opened.
Failure Analysis: First post pick fault reproduction, beginning with a remote control lock, unlock five or six times normal, and the hazard warning lights launch scanner flashing also normal. Then try again, each locking hazard warning lights flash once, when you unlock the door does not move, the hazard warning lights are not flashing, then use the mechanical key to unlock the vehicle without warning. However, when the lock with a mechanical key lock first, and then the remote control the door can be opened.
I suspect this is the left front door lock is not in place, or lock dust, unlocking astringent lead. Remove the door clean, simultaneous measurement of the left front door lock and unlock switch only when the lock-resistance of less than 1Ω, infinite resistance when released, when you unlock renault clip the resistance less than 1Ω, normal. Lock motor resistance is normal, after loading the fault persists.
Then re-analysis, remote unlock signal emitted, the first to go through the door control receiver receives, then the signal is sent to the right of the main body ECU, if the door control receiver fails, it will not lock the door; but now locks only normal, but sometimes also open the door, indicating that the door control receiver and the remote control should be no problem. In this regard, will focus on the right side of the main body ECU. The door is closed, press the lock button on the remote control, measuring the 9th line and body blacksmith RJ plug on the right side of the main body ECU, there is a high voltage output; When you press the unlock vcs scanner button, measuring RJ plug on the 17th line and body ride iron, no voltage output, indicating the right side of the main body ECU is faulty.
Troubleshooting: Replace the right side of the main body ECU, troubleshooting.
Failure revelation: Although this is a small fault, but the maintenance staff if not after careful analysis, treatment may be a little difficult, so they need to learn.
Failure Comments: ECU problem determination, you need to pay more effort, especially in terms of determination. After all, the ECU of the failure probability is very low. Of course, if the conditions, using parts replacement method is also very good choice.

Brake and speedometer pointer abnormal vibration
Production plant: Toyota Motor Corporation
License plate number: Crown MS125
Production year: 1960
Failure symptoms: abnormal sound generated near the front wheel, speedometer pointer occasionally vibrating abnormally
Diagnosis: First unbundled brake system check, the results of the brake disc friction pad wear, but there are residues from the wear limit. Disc rotor does not vibrate. Wheel bearings are also not produce shoulder (stairs) shape wear, brake caliper moving parts also normal. The car is equipped with ABS system is currently very popular (anti-lock braking system). The sensor is removed, check the sensor-driven skp 900 v2.7 organization, the result is no exception. Once again, make a trial run, the results are very suspicious noticed the phenomenon, which is abnormal sound braking, the brake pedal and the speedometer pointer bounce vibration is synchronized to happen. This is the ABS system is considered abnormal, so unplug speed sensor connector, ABS stops the action, and then running test. After starting the engine, ABS brake system warning light lit up, indicating that the ABS system abnormalities. In this state the actual driving, no abnormal sound, the brake pedal does not rebound, completely normal. But the speedometer pointer still vibrating, it seems that the ABS system is abnormal. But if the electrical system is abnormal, then the ECU perception after, you should stop the action, while the warning lights should alarm. From the above analysis does not seem abnormal electrical systems, but there is some kind of failure associated with the speedometer, the actual inspection speedometer cable, driven gear, the results of the meter body, instrument cables are no exception, but in the back of the transmission is equipped with a gear box, filled with the rear wheel speed sensor ABS system. This is consistent with the front two wheel speed sensor, rear side of a wheel speed carsoft 6.5 sensor specifications. This sensor is mounted in the form of one of the driven gear box, a look removed, almost fell off from the gear shaft press-fitted, has two-thirds wear.
Inferred from this situation, ECU can not normally get information on the drive shaft, which is ECU a while to get the drive shaft rotation signal, while they get the shaft stop signal, continuous input strange signal. ECU think rear wheel is locked state, issued a directive indicating lower rear wheel hydraulic brakes. That is, because the driven gear exception, so the speedometer pointer vibrate, and the brake pedal occur rebound. Front brakes produce different sounds at the same time, it should be the sound of the engine compartment incentives generated.

Lexus cars idle instability, weak acceleration
Symptom: There is a Toyota Lexus brand produced by advanced automobile (using hot wire V8 gasoline injection engine) idle instability, weak acceleration, exhaust pipes and other symptoms of overheating.
Failure Check: After turning the car fault diagnosis system, fault light alarm. Detected by the decoder fault code is "25" and "26" (i.e., air-fuel ratio A / F is too thick and too lean code), the fault launch crp129 reviews code contradictory. Since the fault code contradictory, repair personnel initially at a loss. Later, the ignition timing is suspected error or bad fuel injector work. If the injector bad job, amount of oil in the cylinder will been uneven; fastening screw loose if the distributor, will inevitably lead to early evening when the combustion condition of the mixture also will good times and bad times when the ignition with gasoline when the supply of similar uneven. Based on the above judgment, will replace all the injectors and re-tighten the distributor and adjust the ignition timing, the fault still exists. Detection engine cylinder pressure, the value of normal. Finally, the use of a vacuum table for intake manifold vacuum ΔPx were tested and found that its value is only 50 kPa (vacuum pressure when idling vcs stable under normal conditions should be 65 kPa -72 kPa), also found on the left side of the ignition coil issued weak spark. So far, the initial determination is left of the ignition coil failure.
Troubleshooting: Replace the left side of the ignition coil, spark associated with high pressure returned to normal; after re-starting the engine, intake manifold vacuum ΔPx rapid recovery. After eliminating the fault code, test, the engine returns to normal.
Failure Analysis: Because the left side of the ignition coil to generate a fault, so that the effective working cylinder of the engine is significantly reduced, the power loss is large, resulting in a lower intake manifold vacuum ΔPx, not part of the combustion gas mpps v16 mixture in the exhaust in the exhaust pipe Shiyou the high-temperature gas ignited. Due to different degrees in different conditions in the mixed gas is ignited, it is the oxygen sensor detects the concentration of the mixture of different fault signals.

Consolidated fault analysis Crown car engine
Symptom: a crown top car (92 models 3.OL GZS133), has traveled 250,000 km, fuel injector cleaning light after the car accelerated idling decreased from 750r / min 200r / min, and sometimes even destroy cars; hard acceleration exhaust pipe oil revenues have "bam" sound; when 20-4Okm / h fuel and oil revenues rear chassis has "Hang Hang" different sound.
Failure Analysis: This car cleaned fuel injectors, oil flow, the fuel injection mercedes c3 quantity will increase in the same amount of fuel injection pulse width. Light step on the accelerator pedal, the engine ECU received a disconnect signal from the throttle position sensor idle contact, perception of the engine has been idling condition to transient condition. At this point, the engine ECU control the stepper motor type idle valve to return to the maximum opening position, while the throttle is opened, airflow through the throttle valve into the intake chamber, two aspects of the role of the intake indoor negative change. This change negative pressure sensor signal to the engine ECU, thereby increasing the amount of fuel injection to improve speed. The reason is because the failure occurs after cleaning fuel injectors, fuel injection is too large to make the mixture too thick, causing the car idling to reduce or even eliminate, maintenance is simple: the engine compartment on the right side there is a mixture adjustment valve, as long as there is exhaust gas analyzer under the circumstances, adjustment of the mixed can clip gas to the lean side (note: the adjustment must not too much so as not to affect the power output of the engine) that is changing the fuel injection pulse width, the fuel injection quantity is reduced, then the fault would eliminate the phenomenon.
Oil revenues when hard acceleration, the exhaust pipe of "bam" sound, the cause of the failure above, that mixture is too thick or too small ignition energy, combustion in the cylinder can not fully residual unburned mixture combustion in the exhaust pipe, forming blasting. The maintenance method in two steps, first check the ignition timing and the spark plug, when the engine water temperature is normal, idle 750 ± 50r / min, a load to close the case, check the connection box shorting TE1-E1 terminal to check and adjust the ignition timing supreme BTDC 10 °; Second, under the correct ignition timing and spark a good case, dilute the mixture to adjust the valve to the side (Note: must not adjust too much, so as not to affect the engine power output).
Speed of 20-4Okm / h, the fuel and oil revenues, the rear of the chassis has "Hang Hang" sound. Fault location may drive carprog shaft, differential axle shaft, JZS133 type drive shaft for the triple crown sedan type shaft, soft-fit axle, should confirm the fault position and differential drive shaft connecting the first part of the opening, grip live gimbal rotation at one end and the other end, if clearance, replace the drive shaft, without clearance, inspection differential, hand holding and rotating flange, if free travel is too large there may be differential active and passive gear pinion backlash within the device is too large. If the differential without failure, the cause may be a gap between the axle and the ball is too large Cage.

Daewoo Prince excessive idling
Symptom: a prince Daewoo engine idling excessive, turn off the engine when the big shake, that the car is 2.0 displacement engine, four-cylinder, electronically controlled multi-point injection.
Troubleshooting: First of all tubes were certain external examination, the cause is not found. Then check the throttle and idle valve, and found that it too much kess v2 ecu programmer coke and sludge, suspected of issuing and air leaks, then thoroughly wash them, the fault persists after the trial installed. So he replaced the idle valve, but still does not work. So careful analysis that idling excessive because the intake air much reason. How much is the idle air intake valve controlled by a computer instruction and idle valve work, replace the idle valve does not work, indicating the reasons for failure are not idle valve, but in the computer, and then the engine fault light is not bright, electric control decoding data flow detection device, findings show that the engine water temperature is only 17 ℃, and the actual temperature and the instrument panel display serious discrepancies temperature, engine temperature at this time there have been 85 ℃, and upon inspection instrument sets and computer circuit diagram that just do not have the same water VDM UCANDAS temperature sensor. Water temperature sensor for electrically controlled check unplug the plug prong found serious rust, after cleaning up the plug, replace the water temperature sensor, troubleshooting, everything is normal.
Failure Analysis: think through the signal from the temperature sensor, changed (because the resistance to rust at large), enter the computer, the computer judges believe the water temperature is very low, so the instruction plus rich hud mixture and increase the intake air, resulting in a normal idle temperature remains high after the failure, thus believe that the electronic control system after repair, it should be, but after the first simple complex, in order to avoid unnecessary detours.

Cadillac difficulty in starting on their own after flameout
Symptom: an American Cadillac (CADILLAC) car driving on uneven rural roads, the road due to the impact, resulting in strong vibration, resulting in an engine flameout on their own, it is difficult to start after flameout.
Troubleshooting: First start from the circuit system. After examination, the high-voltage ignition is normal, no problem ignition timing. Since the circuit is no problem, the failure is likely to occur in the oil on the road.
The car uses electronic fuel injection device. Its working principle is: each sensor to the engine kess v2 speed, load, air enters the amount of emissions, such as electrical input into an electronic control center (computer ECU), the signal from the electronic control center to record, analyze, compare issued after injection volume, injection timing and other work orders, the executing agency executing the instruction. Therefore, the first step should be to check whether the executive body fuel injection device properly.
First, the fuel injector valve to be checked. The multimeter two test rods were exposed to the injector solenoid valve two terminals, observing voltage indication circumstances. This voltage is controlled by the electronic control center of the output signal is provided, it would normally change with changes choke. Detection result is OK, the fuel injection device failure excluded areas. And then check the fuel pump and found that the pump does not work. Remove the wiring, the car 12V power ck-100 supply with dedicated direct access to the results fuel pump is working properly, indicating that the pump circuit breaker occur. However, check the fuel pump relay, fuse were normal.
The car pump circuit, the device of a protection switch (a safety device, mounted on top of the car rear luggage compartment). The switch is spring when the vehicle collision will automatically jump, immediately cut off the fuel pump power to stop oil supply. After examination, the spring really jump. Press this spring, the protection switch back ON condition, the fuel pump back to normal, normal car engine, fault elimination.

Volkswagen Santana GX sedan idling instability
Mileage over 200,000 km of Shanghai Volkswagen Santana GX sedan. While the engine is able to start the car, but in idle condition is not running smoothly.
Troubleshooting:
(A) Failure Cause Analysis
The reason there are many unstable engine idling, the air supply system blockage or leakage, poor fuel oil supply system, ignition system misfire or weak spark ignition timing is not correct, such as are likely to cause the engine to idle instability .
(2) Troubleshooting Methods
Check carburetor oil, in the normal range; check intake system, without clogging and leak case; check the ignition timing, compliance; checking high voltage fgtech galletto spark with high-pressure fire test methods and found that the spark was weak. Weak spark causes the various components and circuit comprises an ignition coil and the high voltage circuitry and low voltage circuits.
Check the ignition coil resistance, the resistance of the resistance of the primary winding and a secondary winding were within the normal range, check the low pressure line connection without exception; replacement of the ignition coil failure remains. Therefore, the suspected cause of the malfunction outside the high-pressure circuit of the ignition coil. Check the central high-voltage and high-voltage resistance of the sub-cylinder found in many large than normal, indicating high voltage wires are aging.
(3) failure treatment measures
After the replacement of the high-voltage wires, idling unstable fault disappears, troubleshooting.
Failure Analysis: Shanghai Santana GX sedan engine ignition system, the high-voltage wires are formed with a damping resistor for suppressing radio interference. High pressure damping resistor wire and fiber from a mixture of a carbon, a high pressure resistance of the wire after aging BMW ICOM increases, so that high voltage circuit is energized (arcing spark plug) ignition energy consumption increases accordingly, resulting in weakening the spark ignited rate decline, the light engine fuel consumption increases, idling unstable; severe, the engine can not start.
Sometimes encounter resistance of high-voltage wires within the normal range, but due to high voltage wire insulation is damaged and cause leakage, but also may cause difficulty starting the engine, idle instability and other symptoms. Therefore, when high voltage wire maintenance, inspection of high voltage wires should not be overlooked or without breakage.

What Will cause a Chevy Lumina to Heat Up?
The Chevrolet Lumina and its Regal, Cutlass and Grand Prix cousins have been as common an illustration of the typical passenger car or truck as you're going to come across. Front-drive, mid-sized and equipped having a four- or six-cylinder engine, the Lumina will overheat to the same explanations as most other cars do.
Engines need a very exact combination of air and gasoline -- about 14 elements air to one element gas -- to take care of efficient combustion even though nevertheless CK-100 Auto Key Programmer supplying more than enough thermal transfer to maintain the cylinder great. Place just, excessive air burns extra of the fuel than it need to, causing bigger combustion chamber temperatures and overheating. The Lumina's oxygen sensor need to enable to keep items in balance, but it surely can not compensate for a clogged or malfunctioning gasoline injector or even a large vacuum leak.
A clogged cooling technique or possibly a thick coating of contaminants within the engine's aluminum, a malfunctioning drinking water pump or a clogged radiator will lead to coolant temps to rise, as will a thermostat caught possibly shut or half shut. In possibly scenario, thermal strength will fail to transfer through the engine block to the coolant, or from the coolant to your air. Oil is yet another type of coolant that number of frequently consider of; reduced oil force or reduced oil may even result in overheating.
Just about anything that traps exhaust gases from the motor will bring about overheating by holding these gases versus the cylinder head for any extended time period. A collapsed muffler is not not possible, but it is unlikely when compared with a broken or melted-down catalytic multidiag pro converter. This really is a little not as likely with Luminas that make the most of ceramic core converters, or any developed considering that 1996.
Exhaust gases would normally transfer warmth immediately from the exhaust manifold and out in the catalytic converter, but on exceptional instances the recent exhaust gases will go straight to the coolant. This will commonly transpire in the event the head gasket blows, once the block cracks or each time a crack appears inside the cylinder head's exhaust port location. In any case, the coolant process could lose tension, or 500-degree in addition exhaust gases will superheat the coolant.

2007 Honda Accord Shifting Difficulties
Honda, in general, is one of the ideal drivetrain engineering companies on earth. Anybody can build a 1,000-horsepower W-16 engine, but will it move muster on emissions, gas financial system or expense? Nissan builds a great AWD program for its GT-R supercar, but Honda crafted the most beneficial AWD system on this planet for its crossover utility motor vehicles and sedans. So, Honda understands what it is really carrying out with drivetrains -- ordinarily. Alas, from time to time, a bad apple does pop up. From time to time two at a time.
The 2007 Accord built news partly because of its slick and sophisticated six-speed handbook mvci transmission, a notable oddity in a planet brimming with automatics. Nevertheless, this transmission wasn't on the road for lengthy right before house owners started off noticing that it had an odd small quirk. The transmission, nearly from the working day it left the showroom, had a noticeable grind heading into 3rd gear. As time went on, the grinding would worsen, right up until it grew to become possibly extremely hard for getting into third gear, or even the transmission randomly commenced popping out of 3rd. The situation was a lot more noticeable on automobiles operated in colder climates, and was intermittent right before complete failure.
Old-school gearheads with guide transmission knowledge identified these indications nearly instantly. Grinding gears, difficult shifting and popping out of drugs are basic indicators of failing synchronizers inside the transmission. Honda addressed the situation in specialized support bulletin 08-020 dated April 2nd, 2008. In truth, as Honda acknowledged, the afflicted motor vehicles had possibly faulty third gear synchronizers or maybe a defective third equipment shift sleeve. It recommended replacement of the 3rd equipment set. The TSB influenced 2003-to-2007 Accord V-6 designs, and 2006-to-2008 Civics. It absolutely was protected NEC Key Programmre under guarantee for some cars and trucks for the time, but numerous of individuals who had acquired early Accords were caught in the gap amongst warranty expiration and TSB issuance.
For just a few a long time a minimum of, Accord entrepreneurs just could not win when it came to transmission challenges -- even the automated had difficulties. Soon in the manufacturing run, Accord entrepreneurs commenced encountering failures of the secondary shaft bearing, which caused negative shifting that ultimately cascaded right into a failure that made shifting even worse. Drivers who speedily shifted as a result of any in the reverse, neutral or push gears observed which the transmission failed to previous lengthy prior to the secondary shaft bearing unsuccessful. Once it did, progressive failure in the transmission was virtually unavoidable.
In 2011, Honda issued a remember for around one.five million 2005-to-2010, four-cylinder tcs cdp pro Accords, and some-year CR-V and Component crossovers. In accordance to Honda, the change programming in the laptop or computer was as well intense in partaking the gears while shifting from 1 for the upcoming, and failed to allow for one particular to completely disengage ahead of it grabbed another. The ensuing worry broken the output shaft bearing. Honda claims that the problem transpired generally in "unusual" circumstances, as when motorists speedily shifted from reverse to travel though attempting to rock the vehicle outside of mud or snow. The correct was an easy software package update that slowed down engagement of push, neutral and reverse.

Mercedes-Benz 560SEL starting difficulties, exhaust black smoke
Symptom: a Mercedes-Benz 560SEL type electronic injection V8 engine, because the place is too long, difficult start. After starting idle instability, and the exhaust black smoke, the engine accelerated to 5000 rpm or so, start ups and downs, especially powerful.
Troubleshooting: Why start to solve the difficulties. First look at the fuel pump to the engine oil pressure pump oil is normal, so again the spark plug removed for inspection, the results have been drowned gasoline spark plug failure is blocked by the differential pressure valve gasoline dispenser on the basis of this phenomenon can be positive or poor result, the differential pressure valve removed, the differential pressure valve is really dirty actions, after cleaning, the engine smooth start, but after obd scanner starting idle instability, exhaust black smoke, this is because the mixture is too thick here it must be noted, after removing the differential pressure valve clean (as long as the differential pressure valve with electromechanical engines) must be adjusted, usually after the differential pressure valve adjustment screws loose 4-5 laps then, after a good adjustment, troubleshooting. But when the engine is accelerated to 5000 rpm when the throttle foot in the end, is not up to speed, and turn around in 5000 fluctuated, very serious, according to experience, this situation is caused by the engine off the oil. First return pipe with pliers, not to death, then accelerated, found that the situation has improved, it is not enough due to the engine oil pressure caused by high speed, but the front has measured the low-oil pressure is normal, indicating that the pump is good. So remove the pump relay, for a new piece, the failure to completely ruled out.
Failure Analysis: This electromechanical engine is more difficult to repair. Its fuel distributor on the engine fuel injection is mainly played the role of the amount allocated between the two cylinders, but the size of the fuel injection quantity is to rely on the differential pressure valve to adjust the fuel distributor, the adjustment NEC PRO57 screw on the pressure valve, inside tune too much, it will make the mixture too thick black smoke, tune a little, and the mixture is lean, the engine underpowered, so just to be transferred so far. Engine speed and down because the pump relay has two contacts, one pump low speed contact, a high-speed contact, when the engine speed reaches 4000 rpm, the speed on the pump relay contacts should be closed so that the pump high-speed operation, in order to supply engine oil needs, this time, the high-speed contact is not closed, causing the engine oil pressure is not enough, not enough engine speed needs, start the engine speed fluctuated.

Mercedes s320 sedan idling unstable
Symptom: a Mercedes Benz s320 luxury sedan, the engine overhaul after all normal factory, but when the car a month after normal driving, but there has been idle instability and less than 600 rpm, open air, steering has flameout phenomenon, and the good times and bad, sometimes not idle.
Maintenance process: First, the transfer of the fault code, because it is an intermittent fault so no fault code appears, judging by past experience to idle speed stepper motor has a problem, but Benz stepper motor and throttle position sensor as a whole, is more advanced under normal circumstances there will be no problem. The car was out of the way to flush the engine when the car wash for a moment then now this situation, thus it can be concluded from the computer to the line of contact between the stepper motor idling bad actions. First with ordinary odometer correction tool push-pull method, that is, the computer idling motor to the line between pushing and pulling performed, then found the engine speed is high and sometimes low, the line break open the jacket and found the line has been aging, loss, causing the input signal confusion conduct line dressing, then test, everything is normal, troubleshooting.
Failure Analysis: When the steering or air conditioning has played an output signal input into the computer, the computer and then send the signal to the acceleration signal according to the idling motor, which was an increase of 100 rpm the engine would not turn off, but when the aging once the water has caused even the electricity, that the computer output signal, transmitted to the line when it hit the aging of local capacity together several signals, causing signal confusion, not receiving proper idling motor speed signal, and not speed, which what caused the engine to increase the negative, so the engine will stall.

First with ordinary odometer correction tool push-pull method, that is, the computer idling motor to the line between pushing and pulling performed, then found the engine speed is high and sometimes low, the line break open the jacket and found the line has been aging, loss, causing the input signal confusion conduct line dressing, then test, everything is normal, troubleshooting.
Failure Analysis: When the steering or air conditioning has played an output signal input into the computer, the computer and then send the signal to the acceleration signal according to the idling motor, which was an increase of 100 rpm the engine would not turn off, but when the aging once the water has caused even the electricity, that the computer output signal, transmitted to the line when it hit the aging of local capacity together several signals, causing signal confusion, not receiving proper idling motor speed signal, and not speed, which what caused the engine to increase the negative, so the engine will stall.

Mercedes-Benz S500 vehicle can not be started after overnight
A mileage of about 140,000 km of 2005 Mercedes-Benz S500 sedan. Users reflect: the car parked overnight after the vehicle failed to start.
Troubleshooting: the vehicle is turned off, turn off all electrical equipment. Remove the key, put the lid lock switch, door switch and door switch, tail cap switch is in lock car lock status. Access to vehicle power supply circuit with a multimeter's Ground loop, determine the battery voltage is greater than 12V. Found within 20min, battery discharge current is not reduced to 50mA, reach 2A above, there is leakage phenomenon, certainly not sleep module, is awake. To narrow range, first unplug the power cord left front SAM, SAM makes the front left off all power obd news supply modules do not work, the discharge current is not decreased significantly. Then unplug the power cord right front SAM nor decreased significantly. When SAM after unplug the power cord, the discharge current rapid decline, falling to the 50mA, narrowed it down to the SAM above the power module.
After returning to rearm SAM power cord, fuses one by one pulling on the rear SAM. When pulling PSE pump fuse No. 62, the discharge current is normal. Removal of the box on the left tail trim, unplug the PSE pump power plug, plug it back in the fuse, the discharge current normal range, defined as PSE pump is awake. PSE pump itself may have a problem or CAN line, there are so PSE pump is awake and PSE pump receives a signal to the switching signal is awake these three possibilities. PSE pump itself is not considered a problem, make sure the other two reasons. If the CAN line, there are so PSE pump wakeup signal that sends the signal module certainly in working condition. But now only a PSE pump module is awake, there are signals that the CAN line to make PSE pump wake this reason may be less. However, in order to determine what still needs to be detected.
PSE pump back into the power plug, unplug the cord CAN PSE pump, the discharge current is not normal. CAN line obd scanner proved no signal so that the pump is awake PSE (PSE pump CAN plug in X36 / 5 on the bus, the bus X36 / 5 at the door at the left front). The main role of PSE is the door suction pump, central locking, tail door suck and unlock to unlock the fuel tank cap. Switching signal itself received only three main, tail cap switch is released, the tail cap lock switch, RTL button. 3 switches were examined and found to release the tail cap switch resistance is not normal, the switch has a slight adhesions. Unplug this switch plugs, re-testing the leakage situation. PSE pump within a predetermined sleep time, is not in the awake state, the discharge current is normal.
Troubleshooting: After replacing the switch, troubleshooting.
