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 |
|---|---|---|---|
| C1A1100 | Front Radar Sensor Optical Axis Misalignment Malfunction | When the ignition switch is ON, the millimeter wave radar sensor assembly detects beam axis misalignment | ·

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 is replaced, be sure to adjust the millimeter wave radar sensor assembly beam axis, perform front radar acceleration sensor calibration, and clear the vehicle control history for each system.
Perform millimeter wave radar sensor assembly beam axis adjustment.
