C0283

DTC C0283

CIRCUIT DESCRIPTION
The brake pedal position sensor is a potentiometer. The electronic brake control module (EBCM) supplies a 5-volt reference circuit and low reference circuit to the brake pedal position sensor. The brake pedal position sensor signal circuit is a direct input to the EBCM. The EBCM determines the brake pedal position based on the voltage from the brake pedal position sensor. The EBCM converts the brake pedal position sensor feed back voltage to a digital signal and puts it on the class 2 communication bus. If the voltage is less than 0.25 volts, then DTC C0283 will set.

CONDITIONS FOR RUNNING THE DTC
- The EBCM control module must be powered.
- This test is run continuously.

CONDITIONS FOR SETTING THE DTC
The brake pedal position sensor voltage is less than 0.25 volts for a consecutive period of 610 milliseconds.

ACTION TAKEN WHEN THE DTC SETS
When DTC C0283 is set the following will occur:
- The engine drive control is disabled.
- The panic brake assist is disabled.
- The traction control system is disabled.
- The vehicle stability enhancement system is disabled.
- The service vehicle soon lamp will illuminate.

CONDITIONS FOR CLEARING THE DTC
- The current DTC will clear when the fault is no longer present.
- A history DTC clears after 100 consecutive ignition cycles in which no faults have occurred.
- Clear the DTC with a scan tool.
