NOTE: This fault usually occurs after reprogramming the CPC or MCM. The internal clocks of the CPC or MCM do not match. After reprogramming either module, all fault codes must be cleared. Detroit DD16 GHG14 (2014-16) Fault Code: SPN 520261 FMI 31 (MCM) Speed Limitation Fault Due to Powertrain Monitoring Control Detroit DD16 GHG14 (2014-16) Fault Code: SPN 520253 FMI 31 (MCM) Software Reset Due to Internal Monitoring Detroit DD16 GHG14 (2014-16) Fault Code: SPN 520253 FMI 14 (MCM) Software Reset Detected Due to an Error in Engine Speed Plausibility Detroit DD16 GHG14 (2014-16) Fault Code: SPN 520232 FMI 9...

DESCRIPTION:Fuel rail pressure low. MONITORED PARAMETER:Fuel rail pressure. TYPICAL ENABLING CONDITIONS:Closed loop and actual rail psi less than 200 bar (2900 psi) of desired rail psi. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Eight seconds DASH LAMPS:MIL ENGINE REACTION:None VERIFICATION:Steady engine rpm 1400 – 1500: Two minutes. NOTE: When rail pressure deviation is greater than 200 bar while under a load this code is set. PROBABLE CAUSES:1. External fuel leakage between the high pressure pump and fuel injectors.2. Pressure limiting valve (PLV) leakage internally.3. Fuel filter integrity (Loose caps, plugged filters).4. Fuel supply issues (fuel level, fuel aeration,...

NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: If there are any codes present for neutral switch, clutch switch, or prake brake switch fix those first. PROBABLE CAUSES:1. Parameters in engine not configured properly.2. Program MCM2.1 to the latest software release.
