Cruise Main Indicator Light Circuit: Description

WARNING: This page is about a different variant/trim than selected.

When the cruise control system is turned on using the cruise control switch (ON-OFF button), the cruise control indicator light (vehicle-to-vehicle distance control mode) illuminates. The driving support ECU uses these and other indicators to indicate 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.

HINT:

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