DYNAMIC RADAR CRUISE CONTROL SYSTEM Cruise SET Indicator Light Circuit

DESCRIPTION

The power management control ECU illuminates the cruise SET indicator by sending indicator output demand signals to the combination meter assembly via CAN communication. The cruise SET indicator illuminates when the dynamic radar cruise control system is controlling vehicle speed. The cruise SET indicator light circuit uses CAN communication. If the cruise SET indicator is not functioning correctly, check for CAN communication DTCs before troubleshooting this circuit.
