Description:

This fault code indicates that both the cruise ON signal and the resume signal are being detected simultaneously by the PTH control unit. This abnormal condition can be caused by issues with the cruise control module or wiring problems.

Reaction:

When this error is detected, the cruise control system may not function correctly, potentially leading to unstable speed regulation. The system might disable cruise control functionality to prevent unsafe operating conditions.

Recommendations:

Inspect Cruise Control Module (S46):

  • Check the cruise control module for proper operation.
  • Ensure the module is not sending conflicting signals.
  • Verify all electrical connections are secure and free from corrosion.

Test Power Train Hydrostatic Control Unit (PTH):

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

Check Wiring and Connections:

  • Inspect the wiring harness connected to the cruise control module 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 current with the latest updates and improvements.

Consult Technical Support:

  • If the issue persists, contact technical support for further diagnostics and potential component replacement.

Monitor System Performance:

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

Note:

Regular inspection and maintenance of the cruise control module and associated wiring can prevent this fault. Consider environmental conditions such as extreme temperatures or exposure to moisture that can impact electronic component performance.
