REMOVAL AND INSTALLATION


caution When the hydraulic unit (integrated with ASC-ECU) is replaced, after turning the ignition switch ON or OFF (vehicle information from ETACS-ECU is registered), always carry out the calibration of all sensors (steering wheel sensor, G and yaw rate sensor, and brake fluid pressure sensor) at one time (Refer to , and ).
note ASC-ECU is located in the hydraulic unit.
