SPN 630/FMI 14
This fault code indicates a communication interruption between the CPC and MCM. It is caused by either of the following:
- DDDL connecting to the CPC/MCM at a specific time within the first few seconds of Ignition ON, and remaining connected for over 10 minutes
- Sending parameters to the CPC while connected to both the CPC and MCM, and DDDL remaining connected for over 10 minutes
The only required action is to disconnect DDDL, cycle the Ignition switch then reconnect DDDL.
