CRUISE CONTROL SYSTEM Cruise Main Indicator Light Circuit

DESCRIPTION

The hybrid vehicle control ECU illuminates the cruise control indicator by sending indicator output demand signals to the combination meter assembly via CAN communication. The cruise control indicator illuminates when the cruise control system is turned on using the cruise control main switch (ON-OFF button). If a malfunction is detected, the cruise control indicator turns off and a warning message is displayed. The cruise control indicator circuit uses CAN communication. If the cruise control indicator is not functioning correctly, check for CAN communication DTCs before troubleshooting this circuit.
