DYNAMIC RADAR CRUISE CONTROL SYSTEM Cruise Main Indicator Light Circuit

DESCRIPTION

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

• The cruise control indicator illuminates when the dynamic radar cruise control system has been turned on using the ON/OFF. If a malfunction is detected, the cruise control indicator goes out and a warning message is displayed.

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