Description:

This fault code indicates that the reverse pedal channel signal is missing or has an abnormal update rate. This can be caused by sensor issues, wiring problems, or malfunctions in the power train hydrostatic control unit.

Reaction:

When this error is detected, the equipment may experience erratic or improper reverse pedal response, affecting driving behavior and performance. The system logs the fault and may limit reverse motion to prevent damage.

Recommendations:

Inspect Reverse Pedal Sensor (B12):

• Check the reverse pedal sensor for proper operation.
• Ensure the sensor is not damaged and is functioning correctly.
• Verify all electrical connections are secure and free from corrosion.

Test Power Train Hydrostatic Control Unit (PTH):

• Perform diagnostic tests on the PTH control unit to identify any faults.
• Ensure all electrical connections to the control unit are secure and free from corrosion.

Check Wiring and Connections:

• Inspect the wiring harness connected to the reverse pedal sensor for any signs of damage, wear, or loose connections.
• Repair or replace any damaged wiring as necessary.

Update Control Software:

• Ensure the control unit software is up-to-date with the latest fixes and improvements.

Consult Technical Support:

• If the issue persists, contact technical support for further diagnostics and assistance.

Monitor System Performance:

• After addressing the issue, monitor the reverse pedal system to ensure normal operation and that the fault does not reappear.

Note:

Regular inspection and maintenance of the reverse pedal sensor and associated wiring can prevent this fault. Consider environmental factors such as electromagnetic interference that can affect sensor signals.
