Circuit/System Verification

WARNING: This page is about a different variant/trim than selected.

Verify DTC P0641, P0651, P0697, or P06A3 is not set.
- If any of the DTCs are set
  Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
- If none of the DTCs are set
Ignition ON, transmission in Park, and service brake pedal released.
Verify that the scan tool BPP Sensor parameter is greater than 0.25 V.
- If 0.25 V or less
  Refer to Circuit/System Testing .
- If greater than 0.25 V
Verify the scan tool BPP Sensor parameter voltage changes as the brake pedal is applied and is less than 4.75 V when the brake pedal is fully applied.
- If the voltage does not change, or is greater than 4.74 V
  Refer to Circuit/System Testing .
- If the voltage changes and is less than 4.75 V
Verify the scan tool BPP Sensor Learned Position parameter is within 0.1 V of the BPP Sensor parameter when the brake pedal is fully released.
- If difference is greater than 0.1 V
  Perform the Brake Pedal Position Sensor Learn .
- If difference is 0.1 V or less
Verify the BPP Sensor parameter transitions smoothly without any spikes or dropouts when slowly applying and releasing the brake pedal.
- If parameter does not transition smoothly or has spikes or dropouts
  Refer to Circuit/System Testing .
- If parameter transitions smoothly and there are no spikes or dropouts
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
Verify the DTC does not set.
- If the DTC sets
  Refer to Circuit/System Testing .
- If the DTC does not set
All OK.
