NOTE:
  • Before replacing the hybrid vehicle control ECU assembly, refer to Registration.

    Refer to REGISTRATION [08/2019 - 07/2021] , or refer to REGISTRATION [07/2021 - ]

  • 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.
  • If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera adjustment.

    HINT: 

    Forward recognition camera adjustment can be performed by using either One Time Recognition or Sequential Recognition.

    One Time Recognition: Refer to ADJUSTMENT (ONE TIME RECOGNITION) [08/2019 - ]

    Sequential Recognition: Refer to ADJUSTMENT (SEQUENTIAL RECOGNITION) [08/2019 - ]
