CRUISE CONTROL SYSTEM Cruise SET 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 SET indicator light turns on.

• The cruise control SET 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.
