Description:

This diagnostic trouble code (DTC) is generated when there is a park lock engagement signal detected by the control software, even though the reverse drive lever is not in the park lock position. This could indicate a fault in the park lock mechanism or an error during transmission calibration.

Reaction:

Limited or no function of the park lock, affecting vehicle maneuverability and safety.

Recommendations:

Inspect Park Lock Mechanism:

• Check the park lock mechanism for any mechanical faults or obstructions that may prevent it from disengaging.
• Ensure that the park lock actuator is functioning correctly and replace it if necessary.

Verify Lever Position Sensors:

• Inspect the sensors responsible for detecting the position of the reverse drive lever.
• Ensure the sensors are correctly aligned and calibrated. Replace any faulty sensors.

Check Transmission Calibration:

• If the fault occurred during transmission calibration, repeat the calibration process carefully according to the manufacturer’s instructions.
• Ensure that all steps are followed accurately to avoid triggering the fault code.

Inspect Wiring and Connections:

• Check the wiring and connectors associated with the park lock system for damage or disconnections.
• Repair or replace any damaged wiring or connectors.

Update Control Software:

• Ensure that the control software is up-to-date with the latest version from the manufacturer.

Consult Technical Support:

• If the issue persists, consult technical support for further diagnostic procedures or potential hardware issues.

Note:

Regular maintenance and checks of the park lock mechanism and associated sensors can prevent issues related to park lock disengagement. Ensuring proper calibration and functioning of all components is crucial for reliable operation.
