Check the cause
Connect the Electronic Service Tool (EST) to retrieve active DTCs and view real-time data or historical logs
Verify if the dataset installed matches the dataset registered for the machine, as corruption or incorrect updates can trigger this error
Check CAN bus communication to ensure the CSM is communicating properly and inspect for loose or damaged wiring connections causing voltage drops
Repair steps
Clear DTC
Attempt to clear the DTC using the EST or a DTC Eraser tool.
Re-flash module
If the code returns immediately, re-flash the Cab Suspension Module (CSM) with the latest software version using the EST.
