The vehicle information from the main body ECU (multiplex network body ECU) and that stored in the forward recognition camera do not match.

  • Front radar sensor system
  • Main body ECU (Multiplex network body ECU)
  • Forward recognition camera

CAUTION / NOTICE / HINT

NOTICE:

  • 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.
