MONITOR DESCRIPTION
The skid control ECU (brake actuator assembly) has a speed sensor circuit self-diagnosis function.
When the vehicle is stopped, the speed sensor supply voltage exceeds a certain value, and the self-diagnosis function detects an incorrectly installed speed sensor, the skid control ECU (brake actuator assembly) illuminates the MIL and stores this DTC.
