DESCRIPTION

When the cruise control main switch is turned on, the cruise main indicator and "Radar Ready" come on. This indicates the control condition (presence or absence of a vehicle in front, vehicle-to-vehicle distance, and set vehicle speed) and fail-safe state through the CAN communication system. The master warning light and cruise main indicator come on and vehicle-to-vehicle distance information is displayed on the combination meter assembly as the alarm buzzer sounds. Items such as "Dynamic Radar Cruise Sensor Needs Cleaning", "Dynamic Radar Cruise Not Available" and "Check Cruise Control System" are displayed on the multi-information display on the combination meter assembly when the ECM detects signals from each sensor and actuator and sends them to the combination meter assembly via CAN.

HINT:

If the vehicle in front in the same lane significantly decreases vehicle speed or another vehicle moves in front of your vehicle, adequate deceleration cannot be applied and the vehicle-to-vehicle distance will shorten. At this time, the system sounds the buzzer to warn the driver. Each indicator in the dynamic radar cruise control uses CAN for communication. Therefore, if there are any malfunctions in this circuit, check for DTCs in the CAN communication system before troubleshooting this circuit.
