Brake Fluid Pressure Sensor/Switch: Testing and Inspection

Brake Pressure Modulator Valve Pressure Sensor Calibration

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 Chassis
6. Select EBCM (Electronic Brake Control Module)
7. Select Programming
8. Select Brake Pressure Sensor Calibration and follow the scan tool directions to complete the calibration procedure.
9. Calibrate Brake Pressure Sensor? Press the Yes, soft key.
10. Programming successful! Press the Confirm, soft key.
11. Clear any DTCs that may be set.
