DTC No. Detection Item DTC Detection Condition Trouble Area
C1A10 Front Radar Sensor 2 seconds after the power switch is turned on (IG), a signal from the millimeter wave radar sensor assembly indicating that there is an internal malfunction in millimeter wave radar sensor assembly is detected by the forward recognition camera 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 Learning.
