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 perform beam axis adjustment for the forward recognition camera and clear the vehicle control history for each system.

    HINT: 

    Forward recognition camera adjustment can be performed by using either One Time Recognition or Sequential Recognition. When clearing vehicle control history, refer to the following links:

    One Time Recognition: Refer to ADJUSTMENT (ONE TIME RECOGNITION) [07/2020 - ]

    Sequential Recognition: Refer to ADJUSTMENT (SEQUENTIAL RECOGNITION) [07/2020 - ]

  • When replacing the hybrid vehicle control ECU, refer to Registration.

    Refer to REGISTRATION [12/2018 - ]
