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

Cruise Main Indicator Light Circuit

DESCRIPTION

- The hybrid vehicle control ECU detects a cruise control main switch signal and sends it to the combination meter through CAN. The CRUISE main indicator light then 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 the circuit.
