DESCRIPTION
When the pre-collision system is operating, the millimeter wave radar sensor assembly sends brake control signals to the skid control ECU (brake actuator assembly).
When the millimeter wave radar sensor assembly receives a VSC system malfunction signal from the skid control ECU (brake actuator assembly) via CAN communication, DTC C1A50 is stored.
