Monitor Description

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

When the vehicle is being driven, if the value of the speed sensor which is outputting the lowest vehicle speed is significantly lower than the values of the other speed sensors, or the value of the speed sensor which is outputting the lowest vehicle speed is 0 km/h (0 mph), the No. 2 skid control ECU (brake actuator assembly) judges that the speed sensor is malfunctioning and illuminates the MIL and stores this DTC.

Also, when a wheel speed is being output (the wheel is not locked), if the output values of the speed sensors for 2 wheels are stuck at 0 km/h (0 mph), the No. 2 skid control ECU (brake actuator assembly) judges that a speed sensor is malfunctioning and illuminates the MIL and stores this DTC.
