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 (BPP) sensor. The BCM supplies a 10-volt reference through the brake sensor reference voltage circuit to the BPP sensor. The BPP sensor sends a variable voltage signal through the BPP sensor signal circuit to the BCM as the brake pedal is applied.
DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:

CONDITIONS FOR RUNNING THE DTC
The battery voltage must be between 9-16 volts.
CONDITIONS FOR SETTING THE DTC
- A short to ground in the BPP sensor signal circuit is present.
- A short to ground or an open in the 10-volt reference circuit of the BPP sensor.
- A malfunctioning BPP sensor.
ACTION TAKEN WHEN THE DTC SETS
The stop lamps may not function correctly.
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.
