System Outline

1. Speed Sensor 

   Detects the wheel speed of each of four wheels.

2. Skid Control ECU 

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

3. ABS Warning Light 

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

4. Brake Warning Light 

   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. Single light-up of the brake warning light alerts the driver when the ECU detects a malfunction in the brake system.

5. Engine Control Computer 

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