DESCRIPTION:This fault sets when the MCM detects that there is an open on the engine starter relay circuit. MONITORED PARAMETER:Engine starter relay. TYPICAL ENABLING CONDITIONS:Key on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:2 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:No start VERIFICATION:Engine cranking PROBABLE CAUSES:1. Starter relay.2. Starter relay wiring.

NOTE: Please see the step by step troubleshooting procedures for this specific code. PROBABLE CAUSES:1. Starter relay.2. Starter relay wiring.

NOTE: The pressure limiting valve will open when rail pressure is above 1150 bar. The motor control module (MCM) will command a lower rail pressure trying to force the pressure limiting valve closed. If the pressure limiting valve does not close, a fault code is generated. The condition that caused the PLV to open must be addressed. DESCRIPTION:1. Pressure limiting valve.2. Failed to close. MONITORED PARAMETER:Pressure limiting valve. TYPICAL ENABLING CONDITIONS:10 seconds MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:10 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Engine Idle: One minute. NOTE: The PLV will open with...

NOTE:No information available for this code.

NOTE: If codes for other modules are present, fix those first. PROBABLE CAUSES:1. Improper programming of the CPC (Common Powertrain Controller).2. Other failed modules on the truck (Transmission, ABS, Cab controller, etc…).3. Battery/battery cable issues, or electrical issue on truck.
