Monitor Description

WARNING: This page is about a different variant/trim than selected.

The No. 2 skid control ECU (brake actuator assembly) monitors the acceleration sensor zero point calibration for successful completion. When the vehicle is being driven, if the acceleration sensor 1 or acceleration sensor 2 zero point range is outside the normal range, the No. 2 skid control ECU (brake actuator assembly) judges that the acceleration sensor zero point calibration is abnormal and illuminates the MIL and stores this DTC.
