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.
Test Point 12
Test point 12
Hall-effect sensor height adjustment, open circuit
Fault code 12
This fault is stored in the following cases:
1. There is an open circuit in the wire to the Hall-effect sensor fore-and- aft adjustment.
2. The Hall-effect sensor is faulty.
3. The control module is faulty.
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 height 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 on the sensor, replace the electric motor for height adjustment.
- If the fault is still present, replace control module.
Test Point 13
Test point 13
Hall-effect sensor front height adjustment, short circuit
Fault code 13
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.
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 sensor. 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.
Test Point 14
Test point 14
Hall-effect sensor rear height adjustment, open circuit
Fault code 14
This fault is stored in the following cases:
1. There is an open circuit in the wire to the Hall-effect sensor foreand- aft adjustment.
2. The Hall-effect sensor is faulty.
3. The control module is faulty.
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 height 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.
