Adverse Skoda Octavia car air conditioning systems work

Symptom: a 2008 factory Skoda Octavia 1.6 L sedan, manual air-conditioning system, the tuirel s777 cumulative traveling about 80,000 km, reflecting the open air with the owner after ten minutes, the natural air conditioning vent blowing wind, and only after the engine flameout re-start, the air conditioning system to return to normal work. The fault has lasted one week.

Inspection and analysis: Connect VAS 5052 test, the vehicle traveling about 10min air conditioning vent natural wind began to blow. Read conditioning system data block group 1, shown as onboard power supply control unit (J519) issued a shutdown signal conditioned by CAN. Gateway into the list, are not the fault code stored in each control unit.

What is the reason for the air conditioning ktag turned off Nick defender J519 engine flameout after re-launch, the starter engine start feeling the moment seems to have a brief pause, the engine can smoothly start the machine, though, it feels as if the battery power is low. Suddenly thought would not be onboard power supply control unit (J519) detects the battery voltage is too low and closed the air conditioning system? Then open the engine compartment lid to check the battery and found that the car had to replace the battery, the negative terminal oxidation serious, measuring battery voltage of 12.2 V, the air conditioning is turned on to start the engine, and then measuring the battery voltage is only 12 V or so. Measuring the generator output voltage is normal. It seems that the problem is out on the negative battery terminal.

J519 original car's power management function, when the engine is running, J519 detects the battery voltage kess v2 drops below 12.2 V will close the air, due to the negative terminal of the car battery severe oxidation, leading to poor charging system charging, when air conditioning is turned on and after the headlamp high-power electrical equipment, battery voltage is low, thus automatically cut off the air conditioning system to work.

Troubleshooting: Clean the battery negative terminal.

When Honda rhyme can not start the car cooler

When Honda models rhyme (Stream) vehicles, model JHMRN3, 2002 model year, the cumulative traveling 190,000 km.
Symptom: the engine is cold (in the morning) does not start.
Troubleshooting: The car is the first time I was dragged to plant maintenance.
Test found that the SVDI VAG engine is indeed difficult to start, but the starter is operating normally. First, check with HDS, trouble-free code. Then check the ignition system, disconnect the ignition coil wire side of the three-pin connector cable, turn the ignition switch, measure the voltage of the power supply terminals for the battery voltage is normal. Then remove an ignition coil, spark plug mounted on the standby flashover test, spark plug arcing normal operation of the starter, then remove the spark plug to check the car, found four spark plugs have been soaked in petrol head, when it replaced the 4 only the spark plugs, and then test found that the engine can be started immediately with the machine, check with HDS, no abnormalities, the car factory.

On the third day they can not start the car engine, drag to plant dismantling and found gasoline spark plug has been flooded wet, so regular checks. Measurement of cylinder pressure, were about 1.1 MPa, normal. After cummins insite measuring the fuel system pressure is 320 kPa, the pressure to keep the flame 30 min at about 150 kPa, fuel system pressure is normal.

Check the engine with the HDS data stream, also found no abnormal data. Remove the injector testing, each injector fuel injection quantity and atomization well without fouling and leakage phenomenon. Because when the spark plug engine can be started with the drying machine, indicating that the car has an engine start conditions, so the car will be parked in the shop and so the next morning to check again.

The next morning before starting the engine remove the spark plug first observed no petrol head attached to ktag observe the interior of the cylinder through the spark plug mounting hole, with a strong flashlight visible liquid piston crown seems to have the presence of a thin wire with a fixed period of approximately 20mm long White touches top of the piston to obtain the top of the liquid. From the point of view of the liquid sample is not gasoline, antifreeze should be to check the remaining three cylinder piston top, but also have the presence of liquid, thus analysis of phenomena, suspected cylinder head gasket is damaged, but the owners reflect the engine temperature has been normal, check the tank and found antifreeze less about 1.5 L, add enough liquid to cool the machine after starting the engine, can be seen from the mouth of a small amount of added liquid bubbles emerge, accelerating the bubble increases, thus conclude that indeed cylinder head gasket is damaged.

Decided to replace the cylinder head gasket. Remove the cylinder head inspection, the cylinder Transponder Chip head flatness error in 0.15 mm or less, you can continue to use. After replacing the cylinder head gasket test, the engine start-time success. The next morning and then start the test, the engine smoothly with one-time machine, the failure to completely eliminate.

BMW engine temperature is too high

    BMW Mini (MINI) sedan, the cumulative traveling 20,000 km, the engine temperature is too high, sustained high-speed electronic fan running phenomenon in motion.

    It reflects the owner, the ktag car appeared yesterday afternoon indicating high coolant temperature phenomenon, the next day will be just a few minutes after starting the engine with the engine coolant temperature gauge will display the engine temperature is too high, and then touch the radiator the upper and lower tube, the feeling is slightly hot, but did not feel the engine reaches normal operating temperature. After the car for repair, first with GT1 fault detector test, the engine electronic control unit (DME) is no fault code stored, read data stream found that the temperature of the engine coolant is 81 ℃ (car radiator fluid outlet does not coolant temperature sensor, it is impossible to determine the work through the thermostat temperature difference); because the fan is in high speed electronic state, read the refrigerant pressure within the air-conditioning control unit for 0.6 MPa, normal. According maintenance experience, after a long HK201 J2534 VCI period of operation of the engine coolant temperature indicator is too high, but on the radiator, liquid pipe temperature is very low, usually caused by faulty coolant pump, then did not give much thought to the cooling temperature and coolant temperature indicator gauge indicates the temperature difference between the fluid temperature sensor indicates, it is removed to check the coolant pump, coolant pump impeller found no skid marks or broken.

    So what is the cause of the engine temperature indication is too high, sustained high-speed electronic fan running it? By analyzing the vehicle cooling system control components, under normal pressure of the air conditioning system, the DME engine rely on two-wire negative temperature coefficient of coolant a temperature sensor to sense the temperature of the engine, only when the coolant temperature sensor fails, only the Transponder Chip actual temperature of the engine may cause a low, but the meter indicates engine temperature phenomenon. Remove the rear cylinder head coolant temperature sensor to measure its resistance to 510n. Because they do not know the standard range of the sensor, desperation can only replace the coolant temperature sensor, and then test found that the above symptoms disappeared.

    Analysts believe that the real reason for the above phenomenon is due to the coolant temperature sensor failure, causing coolant temperature signal response is too slow, making the engine warm-up time exceeds the maximum limit specified, then the engine entered CN900 Key Programmer the pre-set emergency operation mode, so that the actual engine temperature has not increased. In the actual troubleshooting process, ignoring the difference between the temperature of the coolant temperature coolant temperature sensor and instrument display indication of the details, take a lot of detours lead.

Driving down the risk - car head-up display (HUD) to help your grief!

    We usually look around the car is very sensitive to the slightest mistake there may be accidents. But always found to be driving down at the dashboard of the car, look at real-time speed, battery voltage, etc., in order not to hit other people or other Car HUD objects, very careful. There is usually placed on the car dashboard console will top terms of 100km / h speed limits, to the line of sight from the road over the speedometer, even when only one second, the car has traveled forward 28 m. In related news we often see, because looking down at the instrument or to see when the next smartphone traffic accidents caused by drivers distracted driving, especially high-speed driving at night when the vehicle if the driver down to watch the meter display, the front is more in case of emergency may be due to too late to take effective measures results in more serious accidents. So how to reduce or avoid such a situation?
    Logically, the solution is transferred to the driver to avoid front sight, the sight means is not transferred, the content displayed on the meter or to the phone directly displayed on the front Head Up Display windshield. Based on the above factors, there are already vehicles HUD system is installed, it can be important information, maps and a half on the holographic mirror on the windshield, so the driver does not have to bow, you can see the important information to improve the automotive safety and comfort.
HUD figures show that the rise of the advantages are:
1. The driver does not have to bow, you can see the information in order to avoid the dispersion of attention on the road ahead.
2 pilots do not have the distance between the observation instrument regulating road and near the eyes, which can effectively prevent eye fatigue.
