Faulty signal. Permanent fault
Checking the connectors and components
- Check the connector for the door node and door mirror. Check for contact resistance and oxidation.
Remedy as necessary
- Reinstall the connectors, components etc.
- Ignition on.
Test the door mirror function by changing its position and reading off the end values registered by the door mirror potentiometer.
Hint: The end values for the door mirror potentiometer should be between 1 and 4 V.
Other information:

- Checking wiring and terminals Checking Wiring And Terminals.
Does the door mirror potentiometer operate correctly?
Yes - Verification
No - Checking a faulty signal
-------------------------------------------------
Checking a faulty signal
Check the cable between control module terminal #25A and door mirror terminal #1. Check for a short-circuit to ground.
Check the cable between control module terminal #8A and door mirror terminal #11. Check for a short-circuit to supply voltage. Check for an open-circuit.
DDM/PDM-0030 Door mirror potentiometer, faulty signal
Check the cable between control module terminal #9A and door mirror terminal #9. Check for a short-circuit to supply voltage. Check for an open-circuit.
DDM/PDM-0032 Door mirror potentiometer, faulty signal
Check the cable between control module terminal #10A and door mirror terminal #10. Check for a short-circuit to supply voltage. Check for an open-circuit.
