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:

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
