The solenoid turns on when signals are received from the skid control ECU (master cylinder solenoid) and controls the pressure acting on the wheel cylinders, thus controlling braking force.

Refer to DTCs C1401 and C1402 ().

The skid control ECU (master cylinder solenoid) receives signals from the yaw rate sensor assembly via the CAN communication system.

After replacing the skid control ECU (master cylinder solenoid) or clearing the system information stored in the skid control ECU (master cylinder solenoid), the system information must be stored in the skid control ECU (master cylinder solenoid) again. The system information is automatically stored in the skid control ECU (master cylinder solenoid) when the system enters test mode. If the system information is not stored in the skid control ECU (master cylinder solenoid), DTC C120A is stored.

Refer to DTCs C1401 and C1402 ().

The circuit is used to send control information from the skid control ECU (master cylinder solenoid) to the ECM, and engine control information from the ECM to the skid control ECU (master cylinder solenoid) via the CAN communication system.

Refer to DTCs C1401 and C1402 ().

If a malfunction is detected in the engine control system, the ECM sends a malfunction signal to the skid control ECU (master cylinder solenoid). The skid control ECU (master cylinder solenoid) stores this DTC and prohibits the following controls:
