Brake Fluid Pressure Sensor/Switch: Testing and Inspection

BRAKE FLUID PRESSURE SENSOR CALIBRATION

CAUTION:
Before performing calibration, check that the brake fluid pressure sensor-related diagnosis code is not set.

CAUTION:
After the next operation has been completed, carry out the calibration to make TCL/ASC-ECU learn the neutral position of the brake fluid pressure sensor.
