These units were installed in Mercedes-Benz Actros MP4 trucks. A common cause of malfunction is a malfunction of the gas pedal, and thus the vehicle goes into emergency mode. But we also encountered a complete failure of CAN bus communication with other units in the vehicle.
The most common problems:

Accelerator Pedal Malfunction (DTC: AFFFEC, 3F0A08, 5B0008, 0DF0E3, 0BF0E3, 25F0E3, 24F0E3)

Vehicle emergency mode
DTC: ACFFEE and ADFFEE - Faulty control unit
DTC: EEF7ED - faulty parameters in the control unit
DTC: 460003 and 0F0E03 - CPC - short to positive
