DESCRIPTION
The power management control ECU turns on the cruise control indicator light by sending indicator output demand signals to the combination meter sub-assembly using CAN communication.
The cruise control indicator light illuminates in green when the cruise control system has been turned on using the ON-OFF switch. If a malfunction is detected, the cruise control indicator light changes to amber (w/o multi-information display), or the cruise control indicator light goes out and a warning message is displayed (w/ multi-information display).
The cruise control indicator light circuit uses CAN communication. If the cruise control indicator light is not functioning correctly, check for CAN communication DTCs before troubleshooting this circuit.
