A mileage of about 140,000 km, assembly 2ZR-FE engine of the 2008 Toyota Corolla sedan. Users reflect: the car three days there will be no difficulty in starting the phenomenon is caused by battery power loss. The failure phenomenon has occurred many times.
Failure Analysis: First, the battery using battery tester for testing and found that the battery voltage is low, but the Digiprog 3 test results show good battery needs to be charged, then charge the battery first, to be filled with the test again after placing 2h, show good battery voltage is 12. 67V. Next, the car's parasitic current testing, and found the parasitic current is 122. 6mA, significantly higher than the standard value 30 ~ 50mA, so the car's electrical system description somewhere parasitic current is too big phenomenon. Later communication with the user that the car had installed GPS-ONE anti-theft system), suspected to be caused by parasitic currents Refitting the phenomenon is too large, then the GPS-ONE anti-theft system) v After the addition, the parasitic current is detected again, the results found at this parasitic current is about 6. 61 mA, described at this ialtest link scanner parasitic current is very standard. So you can determine the parasitic current is too large is mainly caused due to electrical conversion.
Troubleshooting: After the installation of electrical equipment removal, troubleshooting.
Failure Comments: After a user to install electrical leakage caused by battery power loss caused by one of the major reasons for the failure occurred demolition can be avoided, but we can not consider the basis of the anti-theft system without removing the GPS on, reduce or avoid excessive current generation do? I believe the answer is yes.
