Inspection procedure

Notice:

Hint:

Operating the ignition switch, any switches or any doors triggers related ecu and sensor communication with the can, which causes resistance variation.

  1. Check can bus line for disconnection (air conditioning amplifier branch wire)

  1. Disconnect the e37*1 or e36*2 air conditioning amplifier connector.

Hint:

  1. Measure the resistance of the wire harness side connector.

Standard resistance: for automatic air conditioning system


For manual air conditioning system




  1. Check wire harness (air conditioning amplifier - battery and body ground)

Mil circuit
Description The mil (malfunction indicator lamp) is used to indicate vehicle malfunction detections by the ecm. When the ignition switch is turned on, power is supplied to the mil circuit, and the ecm provides the circuit ground which illuminates the mil. The mil operation can be checked ...

How to proceed with troubleshooting
Hint: Use these procedures to troubleshoot the sliding roof system. *: Use the intelligent tester. Vehicle brought to workshop Inspect battery voltage Standard voltage: 11 to 14 v If the voltage is below 11 v, recharge or replace the battery before proceeding. Inspe ...

Do-it-yourself service precautions
If you perform maintenance by yourself, be sure to follow the correct procedure as given in these sections. Caution The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become electrically energized. To avoid death or serious injury, obse ...
