FORWARD RECOGNITION CAMERA SYSTEM, Diagnostic DTC:C1A0A

DTC Code DTC Name
C1A0A Front Radar Sensor Region Code Mismatch

DESCRIPTION

The forward recognition camera receives necessary information from the millimeter wave radar sensor assembly.

When the forward recognition camera judges that a millimeter wave radar sensor assembly which is not compatible with the vehicle has been installed, DTC C1A0A is stored.

DTC No. Detection Item DTC Detection Condition Trouble Area
C1A0A Front Radar Sensor Region Code Mismatch After the engine switch is turned on (IG) for 3 seconds or more, the forward recognition camera detects that a millimeter wave radar sensor assembly which is not compatible with the vehicle is installed for 5 seconds or more.

  • Millimeter wave radar sensor assembly

  • Forward recognition camera

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 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.
