Diagnostic Trouble Code (DTC) Information ECM-900D: Notes
Condition
The engine control module (ECM) checks that the signal from the brake pedal position sensor and the signal from the stop lamp switch are reliable. The diagnostic trouble code (DTC) is stored if the engine control module (ECM) registers a fault in the circuit for the brake pedal position sensor, the circuit for the stop lamp switch or in the CAN communication between the brake control module (BCM) and the engine control module (ECM), when the engine is running.
The diagnostic trouble code (DTC) can be diagnosed when the ignition is on and the brake pedal is depressed.
Substitute Value
Cruise control switched off.
Possible Source
- Fault trace the brake control module (BCM) and the central electronic module (CEM).
Fault symptom[s]
- Cruise control does not function at all.
