A Mercedes Actros MP4 with intermittent accelerator-pedal response, starting or driveability issues, or no communication with related control units may have a Common Powertrain Controller (CPC3) fault. The CPC is a key HGV control unit. It must be diagnosed by a competent commercial-vehicle technician; do not replace electronic modules solely from a code description.
Reported Actros MP4 CPC3 fault codes
Codes reported in connection with Mercedes CPC3 faults include ADFFEE, ACFFEE and EEF7ED, which identify the A3 driving-control unit/CPC as defective. Other related reports can include 0DF0E4, 0BF0E4, CF040E, 580604, 3F0A08 and 5B0002. The full diagnostic context is essential, particularly where pedal, power supply or CAN wiring faults are also present.
Symptoms to investigate
- Accelerator pedal stops responding intermittently
- Vehicle struggles to accelerate or exhibits driveability concerns
- ECU does not respond to diagnostic equipment
- No communication with the ESP ECU is reported
- CAN or foot-control circuit faults stored
Checks before sending a CPC3
Record all codes, inspect power and earth supplies, and test the relevant pedal and CAN wiring. Some stored codes specifically reference a short circuit, interruption or component fault. Eliminating an external wiring or component issue first helps ensure the correct repair decision.
