BRAKE FLUID PRESSURE SENSOR CALIBRATION
cautionWhen the ASC-ECU has been replaced, carry out the calibration to make ASC-ECU learn the neutral point of all sensor (steering wheel sensor, G and yaw rate sensor, and brake fluid pressure sensor).
note"All sensor calibration" can perform calibration of G and yaw rate sensor, steering wheel sensor, and brake fluid pressure sensor collectively.
cautionPerform "Steering wheel sensor calibration" , carry out the following two operations:
  • Alignment adjustment <Front>
  • Column switch assembly (integrated with steering wheel sensor) replacement, removal, installation
caution
  • Before performing the calibration, check if the brake fluid pressure sensor-related DTC is set in ASC-ECU.
  • When the DTC other than C2002 is set, carry out inspection according to each troubleshooting procedure.
  • Always perform the calibration with the brake pedal released (stoplight switch is turned off).
1. Park the vehicle on a level surface.
2.
cautionBefore connecting or disconnecting the scan tool (M.U.T.-IIISE), turn the ignition switch to the "LOCK" (OFF) position.
Turn the ignition switch to the "LOCK" (OFF) position. Then connect the scan tool (M.U.T.-IIISE) to the data link connector.
3. Turn the ignition switch to the "ON" position.
4. Select "ABS/ASC/ASTC/WSS."
5. Select "Special function."
6. Select "Sensor calibration."
7. Select "Master cylinder pressure sensor calibration."
8. Turn the ignition switch to the "LOCK" (OFF) position.
9. Turn the ignition switch to the "ON" position.
10. Check whether the DTC is set.
11. Turn the ignition switch to the "LOCK" (OFF) position. Then disconnect the scan tool (M.U.T.-IIISE) to the data link connector.
