HINT:
If the vehicle ahead in the same lane significantly decreases its speed or another vehicle moves in front of this vehicle, adequate deceleration cannot be applied and the vehicle-to-vehicle distance will shorten. At this time, the system sounds the buzzer and the master warning light blinks to inform the driver. This circuit uses CAN communication. Therefore, if there are any malfunctions in the communication circuit, one or more CAN communication system DTCs are stored.
