DYNAMIC RADAR CRUISE CONTROL SYSTEM Cruise SET Indicator Light Circuit

DESCRIPTION

• When the ECM detects a cruise control switch on signal from the cruise control 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.
