CRUISE CONTROL SYSTEM Cruise SET Indicator Light Circuit

DESCRIPTION

The hybrid vehicle control ECU assembly illuminates the cruise control SET indicator by sending an indicator output request signal to the combination meter assembly via CAN communication. The cruise control SET indicator illuminates when the cruise control system is controlling vehicle speed. The cruise SET indicator light circuit uses CAN communication. If the cruise control SET indicator is not functioning correctly, check for CAN communication DTCs before troubleshooting this circuit.
