Checking for permanent or intermittent faults
- Ignition on.
Check if the lamp in the power door mirror lights up and goes out.
Is the lamp in the power door mirror working?
Yes - Intermittent fault
No - Checking for a short-circuit
-------------------------------------------------
Checking for a short-circuit
If the car is equipped with a 10-pin connector
Check the cable between door control module terminal #8B and power door mirror terminal #6. Check for a short-circuit to supply voltage.
Replace the cable if a fault is found.
If the car is equipped with a 16-pin connector
Check the cable between door control module terminal #8B and power door mirror terminal #13. Check for a short-circuit to supply voltage.
Replace the cable if a fault is found.

- To connect the breakout box, see Connecting the breakout box Connecting the Breakout Box
- For further information about signals and other values, see Signal specification Signal Specification, Driver Door Module (DDM) / Passenger Door Module (PDM)
- Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Were any faults found in the cable?
Yes - Verification
No - Replacing the component
-------------------------------------------------
Replacing the component
Check that there are no short-circuits in the bulb holder.
Remedy as necessary.
If no fault is found, replace the lamp in the power door mirror.
Continue - Verification
-------------------------------------------------
Intermittent fault
Check the control module and power door mirror connectors. Check for contact resistance, oxidation and loose connections.
If the car is equipped with a 10-pin connector
Check the cable between door control module terminal #8B and power door mirror terminal #6. Check for an intermittent short-circuit to supply voltage. Check for an intermittent open-circuit.
If the car is equipped with a 16-pin connector
Check the cable between door control module terminal #8B and power door mirror terminal #13. Check for an intermittent short-circuit to supply voltage. Check for an intermittent open-circuit.
Check the lamp and bulb holder if no faults were found.

Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reconnect the components, connectors etc.
- Ignition on.
Check if the lamp in the power door mirror lights.
Does the lamp in the power door mirror light?
Yes - Verification completed

Information
Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit Fault-Tracing
No - Attempt New Test

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).
Do you want to view the information again?
Yes - Attempt New Test
No - Exit fault-tracing
