CRUISE CONTROL SYSTEM Cruise Main Indicator Light Circuit

DTC Code DTC Name
Cruise Main Indicator Light Circuit

DESCRIPTION

  • When the ECM detects a cruise control main switch signal, it sends it to the combination meter assembly through CAN communication. Then the cruise control indicator light turns on.

  • The cruise control 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.

CAUTION / NOTICE / HINT

Note:

When replacing the combination meter assembly, make sure to replace it with a new one.
