DESCRIPTION:Jake Brake stage 2 circuit failed low. MONITORED PARAMETER:Jake solenoid TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Engine Idle: One minute. PROBABLE CAUSES:1. Short to ground between pin 13 of the front two-piece fuel injector valve cover harness connector and pin 32 of the 120-pin ECM connection.2. Jake brake solenoid failure.

DESCRIPTION:The Motor Control Module (MCM) Monitors Rail Pressure After Engine Shut Down and Compares it to a Stored Learned Value. If the Leakage Rate has Increased Past the Learned Value Plus a Set Threshold with All Conditions Met for a Count of Five, this Code Will Log. MONITORED PARAMETER:Fuel rail pressure. TYPICAL ENABLING CONDITIONS:1. Ignition must be off for more than five minutes for MCM to reset for a new drive cycle.2. Prior to shutdown, engine must be above idle (Engine State = Torque Demand) for more than five minutes.3. Fuel Temperature is greater than 35°C (95°F) but less than...

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...

POSSIBLE CAUSES:1. External fuel leakage between the high pressure pump and fuel injectors.2. Pressure limiting valve (PLV) leakage (internal).3. Fuel filter integrity (loose caps, plugged filters).4. Fuel supply issues (fuel level, fuel aeration, leaking fuel lines, fuel restrictions).5. Intermittent loss of engine speed signal .6. High pressure pump internal failure.7. Fuel injector (amplifier or needle) leakage.8. Fuel contamination.9. Rail pressure sensor.10. Motor control module (MCM). PROBABLE CAUSES:1. External fuel leakage between the high pressure pump and fuel injectors.2. Pressure limiting valve leakage (internal).3. Fuel filter integrity.4. Fuel supply issue.5. Intermittent loss of engine speed signal.6. High pressure pump internal failure.7....
