CRUISE CONTROL SYSTEM Cruise Main Indicator Light Circuit

DESCRIPTION

• When the ECM detects a cruise control main switch ON signal from the cruise control main switch, it sends it to the combination meter assembly through CAN communication. Then the cruise control indicator light turns on.

• The cruise control indicator light circuit uses CAN communication. If there is a malfunction in this circuit, check for DTCs in the CAN communication system before troubleshooting this circuit.
