DESCRIPTION

  1. The ECM detects a cruise control switch signal and sends it to the combination meter via CAN and BEAN. Then the CRUISE main indicator light comes on.
  2. The CRUISE main indicator light circuit uses CAN and BEAN for communication. If there is a malfunction in this circuit, check for DTCs in the CAN communication system and multiplex communication system before troubleshooting this circuit.

INSPECTION PROCEDURE

1.PERFORM ACTIVE TEST BY INTELLIGENT TESTER

  1. Connect the intelligent tester to the DLC3.

  1. Check the CRUISE main indicator light by using the Active Test.

    Combination meter: 
    Item
    		Test Details
    		Diagnostic Note
    Cruise Indic
    		CRUISE main indicator light is ON / OFF
    		-

    OK:
    Indicator light comes on / goes off.



NG
GO TO COMBINATION METER SYSTEM
OK


2.READ VALUE OF INTELLIGENT TESTER

  1. Connect the intelligent tester to the DLC3.

  1. Turn the engine switch on (IG) and turn the intelligent tester main switch ON.

  1. Check the Data List for proper functioning of the CRUISE main indicator light.

    ECM (Cruise control): 
    Item
    		Measurement Item / Display (Range)
    		Normal Condition
    		Diagnostic Note
    CCS Indicator M
    		CRUISE main indicator signal (Main CPU) / ON or OFF
    		ON: "CCS READY" ON
    OFF: "CCS READY" OFF
    		-

    OK:
    When cruise control main switch operation is performed, the result will be same as above.
