  • 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 (SEQUENTIAL RECOGNITION) [06/2018 - 08/2021]

  • Before performing troubleshooting, check that the low beam headlights and high beam headlights illuminate correctly.
  • When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly 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.
  • If the forward recognition camera cannot operate due to high vehicle interior temperatures, bad weather (rain, fog, etc.) or fogged up or dirty glass, the automatic high beam system will not operate and the automatic high beam indicator will not illuminate.
  • Before performing troubleshooting, check that the front radar sensor system operates correctly.

    Refer to HOW TO PROCEED WITH TROUBLESHOOTING [06/2018 - 08/2021]
