  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)
