Master cylinder pressure sensor is connected to the skid control ECU in the brake actuator assembly.

DTC C1281/81 can be deleted when the master cylinder pressure sensor sends a master cylinder pressure signal or the Test Mode ends. DTC C1281/81 is output only in the Test Mode.

If a DTC of the motor line is stored, the ABS MOTOR1 (fail safe) relay cuts off the power supply to the ABS MOTOR2 relay and performs fail safe.

While any of the ABS, TRC, VSC, or BA is operating, the skid control ECU (housed in the actuator assembly) turns the ABS MOTOR2 relay on and activates the pump motor in the brake actuator.

If a malfunction is detected in the power supply circuit, the skid control ECU (housed in the actuator assembly) outputs the DTC and prohibits operation with the fail safe function.

This DTC is stored when the IG1 terminal voltage deviates from the DTC detecting condition due to a malfunction in the power supply or charging circuit such as the battery or alternator circuit, etc.

The DTC is cancelled when the IG1 terminal voltage returns to normal.

These solenoids turn on when signals are received from the skid control ECU and control the pressure acting on the wheel cylinders to control the braking force.

The speed sensor detects wheel speed and sends the appropriate signals to the skid control ECU. These signals are used for the ABS control system. This speed sensor contains a sensor IC, which consists of 2 MREs (Magnetic Resistance Element). The speed sensor rotor, which consists of 48 sets of N and S poles that are arranged in a circle, is integrated with the inner race of the hub bearing.
