Description:

This diagnostic trouble code (DTC) is generated under the following conditions:

• If the park lock does not engage, even though the TIA control software commands the park lock position and the tractor’s ground speed is such that engagement is possible.
• If a ground speed signal is present, even though the park lock position is commanded and the TIA control software has received confirmation that the park lock is engaged.

Reaction:

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

Recommendations:

Inspect Park Lock Mechanism:

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

Verify Ground Speed Sensor:

• Inspect the ground speed sensor to ensure it is providing accurate readings.
• Replace the sensor if it is faulty or providing incorrect signals.

Check 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.

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 engagement. Ensuring proper calibration and functioning of all components is crucial for reliable operation.
