Caution / Notice / Hint

NOTE:
  • 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 it will not match the information from the vehicle and a DTC may be stored.
  • When the forward recognition camera is replaced with a new one, make sure to read Before Starting Adjustment, then perform optical axis alignment for the forward recognition camera and clear the vehicle control history (RoB) 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:

    Refer to TARGET ADJUSTMENT(ONE TIME RECOGNITION) [10/2022 - ]

    Sequential Recognition:

    Refer to TARGET ADJUSTMENT(SEQUENTIAL RECOGNITION) [10/2022 - ]

    Driving Adjustment:

    Refer to DRIVING ADJUSTMENT [10/2022 - ]

  • When the forward recognition camera is replaced, update the ECU security key.

    Refer to UPDATE ECU SECURITY KEY [06/2020 - ]
