U210787 (Engine Control Module - ECM)

Diagnostic trouble code (DTC) information ECM-U210787

Condition
Engine control module (ECM) uses signals from Forward Sensing Module (FSM) and from Central electronic module (CEM) to provide brake support in case of collision risk (included in adaptive cruise control function).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- One of the input signals from Forward Sensing Module (FSM) is lost.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.

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
- None.

Possible source
- Fault-trace the Forward Sensing Module (FSM).
- Open-circuit in the communication cable.
- Short-circuit to ground in the communication cable.
- Short-circuit to supply voltage in the communication cable.
- Contact resistance or oxidation in the terminals.
- Open-circuit in terminals.
- Short-circuit in connections.

Fault symptom[s]
- Text window and warning symbol/Text message
