Description:

This diagnostic trouble code is generated when the PL3 control software detects a ground speed of more than 0.1 km/h (0.06 mph) for longer than 0.7 seconds after engaging the park lock. This indicates that the vehicle is moving despite the park lock being engaged.

Reaction:

The control software may limit or disable the functionality of the park lock.

Recommendations:

Inspect Park Lock Mechanism:

• Check the mechanical components of the park lock for any signs of damage or wear. Repair or replace as necessary.

Check Sensors:

• Inspect the sensors that detect ground speed and park lock engagement. Ensure they are functioning correctly and replace any faulty sensors.

Verify Control Software:

• Ensure the control software is up-to-date and correctly programmed. Reprogram if necessary.

Examine Wiring and Connections:

• Check the wiring and connections related to the park lock and speed sensors for damage or loose connections. Repair or replace as needed.

Note:

Proper functioning of the park lock is critical for vehicle safety. Address this issue promptly to ensure the vehicle remains stationary when the park lock is engaged.
