Wiring diagram
Inspection procedure
- Perform active test by intelligent tester (security indicator light)
- Select the active test, use the intelligent tester (with can vim) to generate a command, and then check that the security indicator light operation is normal.
Ok: security indicator light turns on / off.
- Check wire harness (transponder key ecu - security indicator light)
- Disconnect the e46 ecu connector.
- Disconnect the e22*1 or e23*2 light connector.
- 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
- Inspect transponder key ecu (output)
- Remove the transponder key ecu with its connectors still connected.
- Measure the voltage of the ecu.
Standard voltage 
Replace clock sub-assembly (for manual air conditioning system), heater control panel (for automatic air conditioning system)
