Description
- When the brake pedal is depressed, ICC brake switch is turned OFF and stop lamp switch is turned ON.
- ICC brake switch signal is inputted to ECM. ECM transmits the data to the ICC sensor integrated unit with CAN communication.
- Stop lamp switch signal is inputted to ECM and the ABS actuator and electric unit (control unit). ECM and the ABS actuator and electric unit (control unit) transmit the data to the ICC sensor integrated unit with CAN communication.
