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.
