Cruise Main Indicator Light Circuit

CRUISE CONTROL: CRUISE CONTROL SYSTEM: Cruise Main Indicator Light Circuit

Cruise Main Indicator Light Circuit

DESCRIPTION

- 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.
- 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

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM
(a) Connect the Techstream to the DLC3.
(b) Check the CRUISE main indicator light by using the Active Test.
Combination meter:






OK:
Indicator light comes on / goes off.
NG -- GO TO COMBINATION METER SYSTEM
OK -- Continue to next step.
2. READ VALUE USING TECHSTREAM
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG) and turn the Techstream main switch ON.
(c) Check the Data List for proper functioning of the CRUISE main indicator light.

ECM (Cruise control):





OK:
When cruise control main switch operation is performed, the result will be same as above.
NG -- REPLACE ECM
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
