Circuit/System Verification

Verify that DTC C0277, C0297, or B3445 is not set.
- If DTC is set, refer to Diagnostic Trouble Code (DTC) List - Vehicle .
Ignition ON, observe the scan tool EBCM BPP Signal parameter. The reading should be Released and change between Applied and Released when pressing and releasing the brake pedal.
- If not within the specified value, perform the scan tool BCM BPP Sensor Calibration procedure.Refer to Brake Pedal Position Sensor Calibration . If the DTC resets, replace the BPP sensor.
Ignition ON, observe the scan tool EBCM Brake pressure Sensor Input Voltage parameter. The reading should be 0.3-0.6 volts when the pedal is Released, and change between 0.3-4.5 volts when Applied.
- If not within the specified value, replace the BPMV. If the DTC resets, replace the EBCM.
