C0283
DTC C0283
CIRCUIT DESCRIPTION
The brake pedal position (BPP) sensor is a potentiometer. The electronic brake control module (EBCM) supplies a 5-volt reference circuit and low reference circuit to the BPP sensor. The BPP sensor signal circuit is a direct input to the EBCM. The EBCM determines the BPP based on the voltage from the BPP sensor. The EBCM converts the BPP 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.
DTC DESCRIPTOR
This diagnostic procedure supports the following DTC:
DTC C0283 Brake Pedal Position Sensor Circuit Low
CONDITIONS FOR RUNNING THE DTC
- The EBCM must be powered.
- This test is run continuously.
CONDITIONS FOR SETTING THE DTC
The BPP sensor voltage is less than 0.25 volt 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.
