CRUISE CONTROL SYSTEM Cruise Main Indicator Light Circuit

DESCRIPTION

• The ECM detects a cruise control switch signal and sends it to the combination meter via the CAN communication line. Then the cruise control indicator light comes on.

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