Description: Motor Control Module Engine Hours Data Higher than Expected
Troubleshooting:
NOTE: The common powertrain controller (CPC) digital outputs have the same SPN as some
motor control module (MCM) faults. DDDL 7.X makes the distinction between the MCM and
CPC when diagnosing a fault.
POSSIBLE CAUSES:
1. MCM engine hours data higher than expected.
2. After reprogramming MCM.
3. After reprogramming CPC.
4. CPC or MCM internal clocks not matching.

Description: Under-Capacity in the High Pressure Circuit
Troubleshooting:
NOTE: The motor control module (MCM) monitors the rail pressure and when rail pressure
deviation is greater than 200 bar, the MCM sets the code.
POSSIBLE CASUES:
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 failure.
10. Faulty motor control module (MCM).

Description: Rail Pressure Level for Injection Enabling Not Reached
Troubleshooting:
NOTE: The motor control module (MCM) monitors the rail pressure and when rail pressure
deviation is greater than 200 bar, while under a load, the MCM sets the code.
POSSIBLE CAUSES:
1. External fuel leakage between the high pressure pump and fuel injectors.
2. Pressure limiting valve 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.
