Brake Pedal Position Sensor Learn

Brake Pedal Position Sensor Learn is a procedure for the ECM to determine the position of the brake pedal position (BPP) sensor when the brake pedal is in the released position.

Note: The Brake Pedal Position Sensor Learn procedure is required when the following service procedures have been performed:

* An Engine Control Module Replacement

* A BPP Sensor Replacement

* Any repair procedure that effects the BPP Sensor alignment

1. Ignition ON, Engine OFF. Verify with the scan tool, that no DTCs are set in the ECM or other control modules on the vehicle. If other DTCs are set, repair those DTCs first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.

2. Clear the ECM of all DTCs.

3. Ignition OFF for 2 minutes. Open and close the driver's door.

4. Perform the following procedure twice:

Note: Do not allow your foot to rest on the brake pedal in the fully release position when performing the following steps.

1. Ignition ON, Engine OFF, transmission in Park, brake pedal in the fully released position.

2. Depress the brake pedal fully. Release the brake and wait 10 seconds.

3. Again, depress the brake pedal fully for a second time and release the brake pedal.

4. Ignition OFF for 2 minutes. Open and close the driver's door.

5. After performing the steps for a second time, the brake pedal sensor should be at the true minimum learned position.

6. Ignition ON, Engine OFF. Verify with a scan tool, the brake pedal position sensor learned release position parameter value does not change values, after several brake pedal applications.

7. Perform the Body Control Module (BCM) brake pedal position sensor calibration. Refer to Brake Pedal Position Sensor Calibration Brake Pedal Position Sensor Calibration.
