CRUISE CONTROL SYSTEM Cruise Main Indicator Light Circuit

DESCRIPTION

• The ECM turns on the cruise control indicator light by sending indicator output demand signals to the combination meter assembly using CAN communication.

• The cruise control indicator light illuminates when the cruise control system has been turned on using the cruise control main switch (ON/OFF). If a malfunction is detected, the cruise control indicator light goes off and a warning message is displayed.

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