DYNAMIC RADAR CRUISE CONTROL SYSTEM Cruise SET Indicator Light Circuit

DESCRIPTION

• The ECM turns on the cruise control SET indicator by sending indicator output demand signals to the combination meter assembly using CAN communication.

• The cruise control SET indicator illuminates when the dynamic radar cruise control system is controlling vehicle speed.

• The cruise control SET indicator circuit uses CAN communication. If the cruise control SET indicator is not functioning correctly, check for CAN communication system before troubleshooting this circuit.
