Checking for permanent or intermittent faults
- Ignition on.
Press the switch for the power door mirrors to check the function of the power door mirrors in all directions.
Also check that folding in of the rearview mirrors works on vehicles equipped with this function.
Can the power door mirrors be maneuvered?
Yes - Intermittent fault
No - Checking the connectors
-------------------------------------------------
Checking the connectors
- Ignition off
- Check that fuse 11C/35 or 11C/36 in the integrated relay / fusebox in the passenger compartment is intact
- Check the power door mirror connector for contact resistance and oxidation. Remedy.
In particular, check for any damage
- Reinstall the components, reconnect the connectors etc.
- Ignition on.
Press the switch for the power door mirrors to check the function of the power door mirrors in all directions.
Remedy as necessary.

Can the power door mirrors be maneuvered?
Yes - Verification
No - Checking for a short-circuit
-------------------------------------------------
Checking for a short-circuit
Check the cable between the door control module and the power door mirror (as follows). Check for an open-circuit.
Control module terminal #26A and power door mirror terminal #15.
Control module terminal #27A and power door mirror terminal #7.
Control module terminal #28A and power door mirror terminal #16.
Control module terminal #29A and power door mirror terminal #14.
Control module terminal #11B and power door mirror terminal #8.
Remedy as necessary.
Try replacing the door mirror if no fault is found.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
