DESCRIPTION
The hybrid vehicle control ECU assembly turns on the cruise control indicator by sending indicator output demand signals to the combination meter assembly using CAN communication.
The cruise control indicator illuminates when the cruise control system has been turned on using the cruise control switch (ON/OFF button). If a malfunction is detected, the cruise control indicator goes off and a warning message is displayed.
The cruise control indicator circuit uses CAN communication. If the cruise control indicator is not functioning correctly, check for CAN communication DTCs before troubleshooting this circuit.
CAUTION / NOTICE / HINT

Before replacing the hybrid vehicle control ECU assembly, refer to Service Bulletin.
