CRUISE CONTROL SYSTEM Cruise Main Indicator Light Circuit

DESCRIPTION

• When the ECM detects a cruise control switch signal, 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.
