DESCRIPTION
The driving support ECU assembly turns on the SET indicator light by sending indicator output demand signals to the combination meter assembly via CAN communication.
The cruise control SET indicator light illuminates when the dynamic radar cruise control system is controlling vehicle speed.
The cruise control SET indicator light circuit uses CAN communication. If the cruise control SET indicator light is not functioning correctly, check for CAN communication DTCs before troubleshooting this circuit.
CAUTION / NOTICE / HINT
Note
When replacing the driving support ECU assembly, always replace it with a new one. If a driving support ECU assembly which was installed to another vehicle is used, the information stored in the driving support ECU assembly will not match the information from the vehicle. As a result, a DTC may be stored.
When replacing the combination meter assembly, make sure to replace it with a new one.
