Defect Code 1

Defect Code 1:

*D* Defect code memory: 1 Inclination adjustment:

Explanation: This defect code is stored when the adjustment system moves beyond the operating range of inclination adjustment. Steering column adjustment is
no longer accepted if the defect code is set (inclination and longitudinal adjustment).

Possible cause: The measured voltage value of the potentiometer feedback is outside the permissible range.

Troubleshooting: The measured voltage value of the potentiometer feedback is outside the permissible range.Troubleshooting: Check wires to the adjustment motor for inclination adjustment, repair if necessary: Adjustment direction "down": From control unit connector X 18098 Pin 1 to connector X 18096 Pin 2. Adjustment direction "up": From control unit connector X 18098 Pin 2 to connector X 18096 Pin 1. If defect is not repaired, check wires from the LSM control unit to potentiometer for inclination adjustment and repair if necessary: Potentiometer connection 'feedback": From control unit connector X 18099 Pin 5 to connector X 18904 Pin 2. Potentiometer connection supply adjustment direction "up": From control unit connector X 18099 Pin 2 to connector X 18094 Pin 3. Potentiometer connection supply adjustment direction "down": From control unit connector X 18099 Pin 4 to connector X 18094 Pin 1. If all wires and connections are OK, check potentiometer and drive motors for inclination adjustment and repair if necessary.
