C004082 (Engine Control Module - ECM)

Diagnostic trouble code (DTC) information ECM-C004082

Condition
The control module is continuously supplied with information about the position and status of the brake pedal switch from the brake control module (BCM) via CAN communication.
The control module checks the communication with the Brake control module (BCM).
The diagnostic trouble code (DTC) is stored if the control module detects that:
- No communication with the Brake control module (BCM).
- The brake light switch position and brake position switch position (via CAN) do not match.
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
- Cruise control is disengaged when the fault is active.

Possible source
- 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]
- Cruise control does not operate
