- When Monitored:
With the ignition on. The EPPM on board diagnostics loads the EPPM Configuration Data from the TIPM CAN Bus message.

- Set Condition:
This DTC will set if the CAN Bus message was received but the information is invalid or corrupt.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. EPPM System Pre-Diagnostic Procedure.
