Detroit Diesel

NOTE: The motor control module (MCM) monitors the rail pressure and when a leakage rate is greater than 150 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 leakage (internal). NOTE: The MCM monitors the rail pressure and when a leakage rate is greater than 150 l/h this code is set. PROBABLE CAUSES:1. External fuel leakage between the high pressure pump and fuel injectors.2....

NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE:If codes for battery voltages are present, repair those first. NOTE: If code 625-9 present, repair that first. NOTE: Otherwise, the only reason that this code would appear would be because of improper prgrogramming in the ECM.
