from present to not present if the cause of the fault has really been eliminated.
- If the fault is still present, replace control module.
Test Point 10
TEST POINT 10
Hall-effect Sensor Backrest Adjustment, Open Circuit
Fault Code 10
This fault is stored in the following cases:
1. There is an open circuit in the wire to the Hall-effect sensor for backrest adjustment.
2. The Hall-effect sensor is faulty.
3. The control module is faulty.
Fault Effect: No automatic adjustment possible, manual only 500 ms
Elimination:
- Check plug on control module for contact and damage.
- Check wire to sensor for damage.
- 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 no fault is detected in the wire, replace the electric motor for seat adjustment.
- If the fault is still present, replace control module.
Test Point 11
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.

2. The Hall-effect sensor is faulty.
3. The control module is faulty.
Fault Effect: No automatic adjustment possible, manual only 500 ms
