  1. Disconnect the e46 ecu connector.
  2. Disconnect the e22*1 or e23*2 light connector.
  3. Measure the resistance of the wire harness side connectors.

Hint:

*1: For manual air conditioning system

*2: For automatic air conditioning system

Standard resistance: for manual air conditioning system


For automatic air conditioning system




  1. Inspect transponder key ecu (output)

Data list / active test
Read data list Hint: Using the intelligent tester's data list allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the data list early in troubleshooting in one way to save time. Connect the intelligent tester (with can vim) to the dlc3 ...

How to proceed with troubleshooting
Hint: *: Use the intelligent tester. Hint: If the display indicates a communication fault in the tester, inspect the dlc3. Hint: Record or print dtcs and freeze frame data, if necessary. Hint: If the engine does not start, first perform the "check dtc" procedures a ...
