CRUISE CONTROL SYSTEM Cruise Main Indicator Light Circuit

DESCRIPTION

• The ECM turns on 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 switch (ON/OFF button). If a malfunction is detected, the cruise control indicator goes off and a warning message is displayed.

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