DESCRIPTION
When the pre-collision system is operating, the millimeter wave radar sensor assembly sends brake control signals to the skid control ECU (master cylinder solenoid)*1 or skid control ECU (brake actuator assembly)*2.
If the millimeter wave radar sensor assembly receives a vehicle stability control system malfunction signal from the skid control ECU (master cylinder solenoid)*1 or skid control ECU (brake actuator assembly)*2 via CAN communication, DTC C1A50 will be stored.

Wireless Charger Illumination Circuit
DESCRIPTION
When the light control switch is turned to the tail or head position, this circuit
sends an illumination signal to the mobile wireless charger cradle assembly. Based
on this signal, the mobile wireless charger cradle assembly dims the indicator lights
(green and amber).
