Detroit DD16 GHG14 (2014-16) Fault Code: SPN 520268 FMI 16 (MCM) Fuel Rail Pressure Too Low, Similar Condition
Posted by PerDiezel Solutions on
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,...

Detroit DD16 GHG14 (2014-16) Fault Code: SPN 520279 FMI 7 (MCM) Starter Inhibit Due to Software Control Monitor
Posted by PerDiezel Solutions on
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.
