DTC C0241-C0254 or C041-C054





Circuit Description
The system relays are energized when the ignition is ON and the vehicle speed is greater than 6 km/h (4 mph). The system relay supplies voltage to the solenoid valves and to the pump motor. This voltage is referred to as the system voltage. The EBCM controls the solenoid valves by grounding the control circuit.

Conditions for Running the DTC
^ The ignition is ON.
^ The vehicle speed is greater than 6 km/h (4 mph).
