CAUTION / NOTICE / HINT

NOTICE:
·

Before replacing the main body ECU (multiplex network body ECU), refer to Service Bulletin.

·

When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle. As a result, a DTC may be stored.

·

When the forward recognition camera is replaced with a new one or the windshield glass is replaced or removed/installed, make sure to read Before Starting Adjustment, then perform optical axis alignment for the forward recognition camera and clear the vehicle control history for each system.

HINT:

Forward recognition camera axis alignment can be performed by using either One Time Recognition, Sequential Recognition or Driving Adjustment.

One Time Recognition: Click hereADAS / AD>ADVANCED DRIVER ASSISTANCE SYSTEM>FRONT CAMERA>TARGET ADJUSTMENT(ONE TIME RECOGNITION)

Sequential Recognition: Click hereADAS / AD>ADVANCED DRIVER ASSISTANCE SYSTEM>FRONT CAMERA>TARGET ADJUSTMENT(SEQUENTIAL RECOGNITION)

Driving Adjustment: Click hereADAS / AD>ADVANCED DRIVER ASSISTANCE SYSTEM>FRONT CAMERA>DRIVING ADJUSTMENT


·

Before performing troubleshooting, check that the low beam headlights and high beam headlights illuminate correctly.

·

When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.

·

If the forward recognition camera cannot operate due to high vehicle interior temperatures, bad weather (rain, fog, etc.) or fogged up or dirty glass, the automatic high beam system will not operate and the automatic high beam indicator will not illuminate.

·

Before performing troubleshooting, check that the front radar sensor system operates correctly.
