Detroit DD16 GHG14 (2014-16) Fault Code: SPN 1077 FMI 14 (MCM) Internal or External Leakage of the High Pressure Fuel System (Too High, Leak Down Test)
Posted by PerDiezel Solutions on
NOTE: The motor control module (MCM) monitors rail pressure during engine shut down and compares it to a stored learned value. If the bleed-down rate has changed due to leakage and it is below the learned value, this code will set. DESCRIPTION:Leakage in high pressure fuel system to high (leak down test). MONITORED PARAMETER:Fuel rail pressure. TYPICAL ENABLING CONDITIONS:Key off MONITOR SEQUENCE:None EXECUTION FREQUENCY:Once when enabling conditions met. TYPICAL DURATION:30 seconds DASH LAMPS:1. MIL2. CEL VERIFICATION:FSIC Leak Test (GHG14) PROBABLE CAUSES:1. If any other codes present, fix those first.2. Clear code and road test. If it doesn’t come back, return...
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 1077 FMI 15 (MCM) Internal or External Leakage of the High Pressure Fuel System
Posted by PerDiezel Solutions on
NOTE: The motor control module (MCM) monitors the rail pressure and when a leakage rate is greater than 100 1/h, the MCM sets the code. There is no fault reaction (limp home mode) associated to this code. POSSIBLE CAUSES:1. External fuel leakage between the high pressure pump and fuel injectors.2. High pressure pump (pumping elements).3. Fuel injector (amplifier or needle) leakage.4. Pressure limiting valve (PLV) leakage (internal). PROBABLE CAUSES:1. If any other codes present, fix those first.2. Clear code and road test. If it doesn’t come back, return vehicle to customer.3. Check for internal and external high pressure fuel system...
