Whether low voltage malfunction of forward recognition camera exists or not

Not Low Voltage or Low Voltage

Not Low Voltage

If this item is "Low Voltage", the camera may have been temporarily unavailable

Front Recognition Camera High Voltage

Whether high voltage malfunction of forward recognition camera exists or not

Not High Voltage or High Voltage

Not High Voltage

If this item is "High Voltage", the camera may have been temporarily unavailable.

Front Recognition Camera Low Temperature

Whether low temperature malfunction of forward recognition camera exists or not

Not Low Temperature or Low Temperature

Not Low Temperature: Approximately -30°C (-22°F) or higher

Low Temperature: Approximately -30°C (-22°F) or less

  • If this item is "Low Temperature", it will display that the camera is temporarily unavailable.
  • If this item is "Low Temperature", X2016 is output in the vehicle control history.
