Caution / Notice / Hint

NOTE:
  • Recognition code registration is necessary when replacing the main body ECU (multiplex network body ECU).
  • If the main body ECU (multiplex network body ECU) is replaced, refer to Registration.

    Refer to REGISTRATION [10/2015 - 08/2019]

  • 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 Learning.

    Refer to ADJUSTMENT [10/2015 - 08/2019]

HINT: 

This DTC is stored when the forward recognition camera cannot store the country specification information received from the main body ECU (multiplex network body ECU). If the forward recognition camera or main body ECU (multiplex network body ECU) has been replaced, check if a forward recognition camera or main body ECU (multiplex network body ECU) from another vehicle was used.
