Cruise Main Indicator Light Circuit

DESCRIPTION

- When the hybrid vehicle control ECU detects a cruise control switch signal, it sends it to the combination meter through CAN communication. Then the CRUISE main indicator light turns on.
- The CRUISE main 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.
