Cruise Main Indicator Light Circuit

DESCRIPTION

1. The hybrid vehicle control ECU 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
