The brake pressure sensor does not require calibration often. Calibration of the brake pressure sensor might be required after certain service procedures are performed. Some of these procedures are as follows:

    • Electronic brake control module (EBCM) replacement
    • Brake pressure modulator valve assembly replacement

The Brake Pressure Sensor Calibration procedure can be completed with a scan tool using the following steps:

  1. Apply the parking brake, or set the transmission in the P position.
  2. Release the brake pedal.
  3. Install the scan tool to the data link connector.
  4. Ignition ON, engine OFF
  5. Select Brake Pressure Sensor Calibration in the EBCM Module Setup list.
  6. Follow the scan tool directions to complete the calibration procedure.
  7. Clear any DTCs that may be set.
