C0283

DTC C0283

CIRCUIT DESCRIPTION
The body control module (BCM) applies a ground through the brake pedal position sensor reference low circuit to the brake pedal position sensor (BPPS). The BCM supplies a 10-volt reference through the brake pedal sensor reference voltage circuit to the BPPS. When the brake pedal is being applied, the brake pedal sensor then sends a variable voltage signal through the BPPS signal circuit to the BCM.

DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC C0283 Brake Pedal Position Sensor Circuit Low

CONDITIONS FOR RUNNING THE DTC
The battery voltage must be between 9.0-16.0 volts.

CONDITIONS FOR SETTING THE DTC
- An open or a short to battery positive voltage or ground on the low reference circuit is present.
- A short to ground or an open in the stop lamp switch signal circuit is present.
- A open or a short to ground in the 10-volt reference circuit of the brake pedal position sensor.
- A short to ground or a short to battery positive in the I/P dimmer control circuit.
- A malfunctioning brake pedal position sensor or BCM.

ACTION TAKEN WHEN THE DTC SETS
The stop lamps will turn on steady.

CONDITIONS FOR CLEARING THE DTC
- The DTC will clear on current status after the condition for setting the fault is corrected.
- A history DTC will clear after 100 consecutive ignition cycles without a fault present.
- A History or current DTC can be cleared using a scan tool.

DIAGNOSTIC AIDS
Perform a visual inspection for loose or poor connections at all related components.
