NOTE: Please see the step by step troubleshooting procedures for this specific code. If any engine compute rhas been programmed or modified lately, clear codes and see if they return. If they do:1. Check ECM programming.2. Follow troubleshooting on 625-9.

NOTE: Fault will set during transmission module reprogramming. If fault occurs while programming, clear code and release vehicle. NOTE: It is normal for this code to appear if you’ve programmed the Eaton Transmission. Just clear the code and release vehicle. PROBABLE CAUSES:1. If any codes related to battery voltage are present, fix those first.2. If 625-9 present, troubleshoot that instead.3. If any engine modules have been programmed recently, check configuration.4. Another computer module on the truck (ABS, transmission, cab, etc…) has a failure that is causing this. Detroit DD16 GHG14 (2014-16) Fault Code: SPN 527 FMI 9 (CPC) J1939 Cruise...

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 condition that caused the pressure limiting valve (PLV) to open must be addressed. DESCRIPTION:Pressure limiting valve, failed to close. MONITORED PARAMETER:Pressure limiting valve. TYPICAL ENABLING CONDITIONS:RP closed loop control & rpm greater than 0. 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 rail pressure is...

NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: This code is typically set because of incorrect wiring of the idle validation switch.
