The millimeter wave radar sensor assembly performs self-diagnosis to check for misalignment of its beam axis. If misalignment is detected, the millimeter wave radar sensor assembly stores DTC C1A1100.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | DTC Output from | Priority |

When replacing the millimeter wave radar sensor assembly, always replace it with a new one. If a millimeter wave radar sensor assembly which was installed to another vehicle is used, the information stored in the millimeter wave radar sensor assembly will not match the information from the vehicle and a DTC may be stored.
When the millimeter wave radar sensor assembly has been replaced with a new one, it is necessary to perform millimeter wave radar sensor assembly beam axis alignment and to clear the vehicle control history. Before performing the Driving Adjustment, make sure to read Before Starting Driving Adjustment.
Beam axis alignment of the millimeter wave radar sensor assembly can be performed using either Triangle Target, Flat Surface Target or Driving Adjustment.
