This diagnostic is typically one of the following:
1. Diesel particulate filter regeneration inhibit switch message contains signal not valid indicator.
2. Diesel particulate filter regeneration force switch message contains signal not valid indicator.
NOTE: Please see the step by step troubleshooting procedures for this specific code.
NOTE: If codes 168-0, 168-14, or 168-18 active fix those first.
NOTE:If code 625-9 active, fix that first as well.
NOTE: If ECM has been programmed recentely, check programming to ensure it is correct.
NOTE: This code is coming from another computer on the vehicle (ABS, Transmission, etc…).
