U010407 (Engine Control Module - ECM)

Diagnostic trouble code (DTC) information

Condition
The control module is continually supplied with necessary information from the Forward Sensing Module (FSM) via CAN communication. The control module checks the communication with the Forward Sensing Module (FSM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- No communication with the Forward Sensing Module (FSM).
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Engine running.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Substitute value
The cruise control function is disabled.
Cruise control cannot be activated.

Possible source
- Fault-trace the Forward Sensing Module (FSM).
- Open-circuit in the control area network (CAN) wiring
- Short-circuit between the control area network (CAN) wiring
- Short-circuit to ground in the communication cable.
- Short-circuit to supply voltage in the communication cable.
- Contact resistance, oxidation or open-circuit in the terminals.

Hint: If several diagnostic trouble codes for communication errors with other control modules in the high-speed network are stored in the Central electronic module (CEM), this indicates some common problem in the CAN-network (see wiring diagram).

Fault symptom[s]
- AQ, Cruise control/Does not engage
