Description:

This error code is triggered by an invalid reverser switch value, indicating that all signals (reverser, park, and neutral) are off. PTI does not read switches directly; switch values are transmitted by the CLC or ACU control unit depending on the vehicle option.

Reaction:

The control unit commands the equipment to enter Park mode, which is recoverable.

Recommendations:

• Inspect Reverser Switches:
  • Check the reverser, park, and neutral switches for proper operation and ensure they are not all simultaneously off.
• Verify Signal Transmission:
  • Ensure the CLC or ACU control unit is correctly transmitting switch values to the PTI.
• Test Switch Circuit:
  • Verify that the switch circuit is free of faults, including loose connections or short circuits.
• Replace Faulty Components:
  • Replace any defective switches or control units that are causing invalid switch values.

Note:

Ensuring correct operation and signal transmission of the switches is crucial for safe and effective control of vehicle movement.
