Test point 15
Hall-effect sensor rear height adjustment, short circuit
Fault code 15
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 the electric motor for height adjustment.
- 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.

Test point 16
Lumbar pressure sensor open circuit
Fault code 18
This fault is stored in the following cases:
1. There is an open circuit in the wire to the lumbar pressure sensor.
2. The pressure 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.
- If no fault is detected in the wire, replace lumbar adjustment.
- Once the cause of the fault has been found and eliminated, actuate the lumbar 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.

Lumbar pressure sensor short circuit
Fault code 19
This fault is stored in the following cases:
1. There is a short circuit in the wires to the pressure sensor.
2. The pressure 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, and on Pin 1 and Pin 3. If a short circuit is
found, check the sensor wires first.
- If no fault is detected in the wire, replace lumbar adjustment.
- Once the cause of the fault has been found and eliminated, actuate the lumbar 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.
