System Outline

Detects the wheel speed of each of the four wheels.

Based on signals from the sensors, it judges the vehicle driving conditions and sends brake control signals to the brake actuator.

Lights up to alert the driver when the ECU detects a malfunction in the ABS system and stops the system.

Lights up simultaneously with the ABS warning light to alert the driver when the ECU detects a malfunction not only in the ABS but also in the EBD. If the brake warning light lights up by itself, then it is indicating that the ECU has detected a malfunction in the brake system.

Sends signals such as park/neutral position switch, TC, etc., to the skid control ECU assembly with actuator.
