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 stopps 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.
