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.
