Elimination:
- Replace support with gear unit.
- Actuate switch for memory seat adjustment.
The text in the fault memory changes from present to not present if the cause of the fault has really been eliminated.
If the fault is no longer present, erase the fault memory.
If the fault is still present, there is a fault in the wire.
For a fault in the wire, proceed as described below:
- Disconnect mirror plug from the control module.
- Disconnect plug at support with gear unit.
- Use an ohmmeter to check for open circuit on the support plug Pin 5 and the mirror plug on the control module Pin 11
Ohmmeter display <5 Ohms
- Use an ohmmeter to check for open circuit on the support plug Pin 7 and the mirror plug on the control module Pin 4.
Ohmmeter display <5 Ohms
- Use an ohmmeter to check for continuity on the support plug Pin 1 and Pin 3.
- If no fault is detected in the wire, replace the control module.
Test Point 21
Test point 21
Pot. mirror right vertical short circuit
Fault code 23
This fault is stored in the following cases:
1. There is a short circuit in the wire to the pot. right rearview mirror.
2. The potentiometer is faulty.
3. The control module is faulty.
Elimination:
- Replace support with gear unit.
- Actuate switch for memory seat adjustment.
The text in the fault memory changes from present to not present if the cause of the fault has really been eliminated.
If the fault is still present, there is a fault in the wire.
For a fault in the wire, proceed as described below:
- Disconnect plug at support with gear unit.
- Disconnect mirror plug from the control module.
- Use an ohmmeter to check for short circuit on the support plug Pin 1, wire colour grey, and Pin 7, wire colour pink. No continuity must be
measured. If no short circuit is detected:
- Use an ohmmeter to check for open circuit on the support plug Pin 3 and the mirror plug on the control module Pin 5
Ohmmeter display <5 Ohms
- Use an ohmmeter to check for continuity on the support plug Pin 1 and Pin 7.
- If no fault is detected in the wire but the fault is still present, replace the control module.

Pot. mirror left horizontal open circuit
Fault code 24
This fault is stored in the following cases:
1. There is an open circuit in the wire to the pot. left rearview mirror.
2. The potentiometer is faulty.
3. The control module is faulty.
Elimination:
- Replace support with gear unit.
- Actuate switch for memory seat adjustment.
The text in the fault memory changes from present to not present if the cause of the fault has really been eliminated.
