Description:

This error code, PTR 000084.07, is generated by the Power Train Reverser (PTR) control unit when it detects that the wheel speed exceeds 0.3 km/h during transmission calibration. This can occur due to the vehicle not being properly stationary during the calibration process, faulty speed sensors, or issues within the control system.

Reaction:

When this error is detected, the calibration process is halted, and the system may display a warning or fault message. The calibration cannot proceed until the issue is resolved and the vehicle is stationary.

Recommendations:

Ensure Vehicle is Stationary:

• Verify that the vehicle is completely stationary before initiating the transmission calibration process.
• Use wheel chocks or other means to ensure the vehicle does not move.

Inspect Speed Sensors:

• Check the wheel speed sensors for any signs of damage, dirt, or misalignment.
• Clean, repair, or replace the sensors as necessary.

Check Wiring and Connections:

• Inspect the wiring and connectors related to the speed sensors and the PTR control unit.
• Ensure all connections are secure and free from corrosion or damage.

Review Calibration Procedure:

• Follow the manufacturer’s recommended calibration procedure meticulously.
• Ensure that all preliminary steps are correctly followed before starting the calibration.

Update PTR Control Unit Software:

• Confirm that the PTR control unit software is up-to-date.
• Apply any available software updates or patches from the manufacturer.

Monitor for Recurrence:

• After addressing the issue, attempt the calibration process again.
• Monitor the wheel speed and ensure the vehicle remains stationary throughout the calibration.

Note:

It is crucial to perform the transmission calibration in a controlled environment to avoid any unintended movement. Regular checks and maintenance of the speed sensors and related components can help prevent this issue. Ensure that all operators are adequately trained in the calibration procedures to minimize errors.
