1. 1

   Check for other OIC diagnostic trouble codes, as they take priority and may cause this communication fault

2. 2

   Physically inspect the rear PTO mud guard switches on the fenders for proper operation, physical damage, or sticking buttons

3. 3

   Inspect wiring harnesses and connectors associated with the rear PTO mud guard switches for damage, corrosion, or loose connections

4. 4

   Verify CAN bus communication using John Deere Service ADVISOR to ensure messages from the OIC/AIC are transmitted and received by the RPT

1. 1

   Resolve Priority Codes

   Clear any higher-priority OIC codes that may be interrupting the CAN bus broadcast.

2. 2

   Repair Wiring

   If diagnostic checks reveal damaged wires, corroded pins, or loose connectors between the fender switches and the cab module, repair or replace the affected wiring harness sections.

3. 3

   Replace Defective Switches

   If the mud guard switch is found to be internally shorted, open, or mechanically defective, replace the switch.

4. 4

   Update Control Software

   Ensure that both the OIC (or AIC) and RPT control software are updated to the latest versions. Install any available OEM patches or updates that specifically address CAN bus communication issues.

5. 5

   Clear and Test

   Clear the fault codes from the system and test the rear PTO operation from both the cab and the fender switches to verify the repair.
