John Deere 522920.09 – Steering System Control Units (XMC and XSC): Incorrect CAN Bus Message, Information from XSC Control Software

Indicates a data transfer problem or timeout between the XSC (Steering System Control Unit) and the XMC (Steering System Control Unit / AutoTrac™ automatic steering system). The .09 extension denotes an abnormal update rate or a timeout waiting for a message on the CAN Bus, affecting the communication and functionality of the machine's automated or active steering systems.

1. 1

   Check for software mismatches between the XMC and XSC modules using John Deere Service ADVISOR.

2. 2

   Inspect the CAN Bus wiring harness and connectors linking the XMC and XSC modules for physical damage, corrosion, or backed-out pins.

3. 3

   Test the CAN Bus circuit with a multimeter for continuity, open circuits, shorts to ground, or high resistance points.

4. 4

   Check for accompanying active CAN Bus codes (e.g., codes ending in .09) that might indicate a broader network failure rather than an isolated steering module issue.

1. 1

   Power Down

   Turn off the machine and disconnect the battery before inspecting the steering control unit harnesses to prevent electrical shorts.

2. 2

   Harness Repair

   If the diagnostic checks reveal damaged wiring or corroded connectors between the XMC and XSC modules, repair or replace the affected harness sections. Ensure all connections are securely terminated.

3. 3

   Software Update (Flash)

   Reconnect the battery and connect John Deere Service ADVISOR. Flash both the XMC and XSC control units with the latest available software updates to resolve any bugs or signal processing issues.

4. 4

   Clear and Retest

   Clear the diagnostic trouble codes. Perform a steering calibration if prompted by the software update, and test drive the machine to verify if the code returns.

5. 5

   Module Replacement

   If the wiring is intact, the software is up to date, and the code persists, the internal CAN transceiver in either the XMC or XSC module has likely failed. Replace the faulty Steering Control Unit.
