CRUISE MAIN INDICATOR LIGHT CIRCUIT

DESCRIPTION



The ECM detects a cruise control switch signal and sends it to the combination meter via CAN. Then the
CRUISE main indicator light comes on.



The CRUISE main indicator light circuit uses CAN for communication. If there is a malfunction in this
circuit, check for DTCs in the CAN communication system before troubleshooting this circuit.

INSPECTION PROCEDURE

1. PERFORM ACTIVE TEST BY TECHSTREAM (CRUISE MAIN INDICATOR LIGHT)

a. Using the Techstream, perform the Active Test.
