VEHICLE STABILITY CONTROL SYSTEM

PRECAUTION

NOTICE: When disconnecting the cable from the negative battery terminal, initialize this system after the cable is reconnected.





CAUTION:
^ When there is a malfunction in the contact point of the terminals or installation problems with parts, removal and installation of the suspected problem parts may return the system to the normal condition either completely or temporarily.
In order to determine the malfunctioning area, be sure to check the conditions at the time the malfunction occurred, such as by DTC output and freeze frame data output, and record it before disconnecting each connector or removing and installing parts.
Since the vehicle stability control system may be influenced by malfunctions in other systems, be sure to check for DTCs in the other systems.
Be sure to remove and install the brake actuator, the skid control ECU and each sensor with the ignition switch OFF unless specified in the inspection procedure.
When removing and installing the brake actuator, the skid control ECU and each sensor, be sure to check that the normal display is output in test mode inspection and DTC output inspection after installing all the parts.
^ After replacing the yaw rate sensor and/or the skid control ECU, make sure to perform yaw rate sensor and deceleration sensor zero point calibration.
^ Since the CAN communication line has its own length and route, it cannot be repaired temporarily with the bypass wire, etc.
