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 23
TEST POINT 23
Potentiometer mirror Left Horizontal Short Circuit
Fault Code 25
This fault is stored in the following cases:
1. There is a short circuit in the wire to the potentiometer left rearview mirror.
2. The potentiometer is faulty.
3. The control module is faulty.
Fault Effect: No automatic adjustment possible
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 plug at support with gear unit.
- Disconnect mirror plug from the control module.
- Use an ohmmeter to check for continuity on the support plug Pin 1 and Pin 7.
- Use an ohmmeter to check for open circuit on the support plug Pin 3 and the mirror plug on the control module Pin 5.
Display: < 5 ohms
- If no fault is detected in the wire but the fault is still present, replace the control module.
