TEST POINT 11
Hall-effect Sensor Backrest Adjustment, Short Circuit

Fault Code 11
This fault is stored in the following cases:
1. There is a short circuit in the wires to the Hall-effect sensor.
2. The Hall-effect sensor is faulty.
3. The control module is faulty.

Fault Effect: No automatic adjustment possible, manual only 500 ms

Elimination:

- Disconnect plug from control module, check for continuity with ohmmeter on Pin 2 and Pin 3.

- If a short circuit is found, check the sensor wires first.

- If no fault is detected in the wire, replace the electric motor for backrest adjustment.

- Once the cause of the fault has been found and eliminated, actuate the fore-and-aft adjustment switch. 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, replace control module.
