DYNAMIC RADAR CRUISE CONTROL SYSTEM Cruise SET Indicator Light Circuit

DESCRIPTION

• The driving support ECU assembly turns on the SET indicator light by sending indicator output demand signals to the combination meter assembly via CAN communication.

• The cruise control SET indicator light illuminates when the dynamic radar cruise control system is controlling vehicle speed.

• The cruise control SET indicator light circuit uses CAN communication. If the cruise control SET indicator light is not functioning correctly, check for CAN communication DTCs before troubleshooting this circuit.
