The brake pedal load sensing switch is turned on when the brake pedal is depressed with force exceeding a predetermined level.

The skid control ECU detects if the brake pedal is depressed or not via this circuit.

If a malfunction in the engine control system is detected, the operations of VSC and TRC are prohibited by the fail safe function. When the signals from the engine are input normally, the fail safe is cancelled and the DTC is not stored.

The ABS solenoid relay supplies power to the ABS solenoid and TRC solenoid.

The solenoid relay is turned on 1.5 seconds after the engine switch is turned on (IG), and is turned off if an open or short in the solenoid is detected by self diagnosis performed when the vehicle starts running.

The ABS solenoid relay is housed in the skid control ECU in the actuator assembly.

The skid control ECU (housed in the actuator assembly) inputs the stop light switch signal and the condition of brake operation.

The skid control ECU has an open detection circuit, which outputs this DTC when detecting an open in the stop light input line while the stop light switch is OFF.
