1. 1

   Inspect CAN Bus wiring for defects, damaged wires, loose connections, or corroded pins between the TIQ and RPT modules

2. 2

   Verify communication using a diagnostic tool (e.g., John Deere Service Advisor or Jaltest) to monitor CAN Bus messages between the TIQ and RPT

3. 3

   Check for electrical interference and ensure proper grounding and shielding of the CAN Bus cables

4. 4

   Assess software health to see if there are software bugs hindering communication or if excessive traffic/conflicts are occurring on the CAN Bus

1. 1

   Reboot the System

   Perform a soft reset or reboot of the control units involved to clear any transient errors or glitches in the system.

2. 2

   Repair Wiring

   If the physical inspection revealed loose, damaged, or corroded wires/connectors between the TIQ and RPT modules, repair or replace the faulty wiring harness sections.

3. 3

   Update Software

   Install any available firmware updates or patches for both the RPT and TIQ control software to resolve known bugs.

4. 4

   Isolate Network Traffic

   If excessive traffic is detected on the CAN Bus, temporarily reduce the number of active devices or reconfigure network settings to isolate the issue.

5. 5

   Test Functionality

   After making necessary repairs or adjustments, conduct thorough testing to ensure that messages are being correctly received by the TIQ and that full machine functionality has been restored.
