Precautions in Sensor Calibration

ESP® control module stores calibration points data of yaw rate/G sensor assembly and master cylinder pressure sensor. Steering angle sensor stores calibration point data of itself.

Traction control system, stability control system, hill descent control (if equipped) and hill hold control (if equipped) use these sets of data. When the following operation is done, calibration should be performed since the original calibration points are deleted.

Sensor	Procedures required calibration
Steering angle sensor	Power is not supplied to steering angle sensor. (battery and/or fuse is removed.) Steering angle sensor is replaced. Power is not supplied to ESP® control module. (battery, fuse and/or connector is removed.) ESP® hydraulic unit/control module assembly is replaced.
Master cylinder pressure sensor	ESP® hydraulic unit/control module assembly is removed or replaced.
Yaw rate/G sensor assembly	Yaw rate/G sensor assembly is removed or replaced. ESP® hydraulic unit/control module assembly is replaced.

Perform sensor calibration according to SENSOR CALIBRATION OF ESP® COMPONENTS .
