The driving support ECU assembly uses the millimeter wave radar sensor assembly to detect objects in front of the vehicle.

Based on this signals from the millimeter wave radar sensor assembly, the driving support ECU assembly sends pre-collision system control operation signals.

If the driving support ECU assembly receives an internal malfunction signal from the millimeter wave radar sensor assembly, it stores DTC C1A10.

  • 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. As a result, a DTC may be stored.

  • When the millimeter wave radar sensor assembly is replaced with a new one, adjustment of the radar sensor beam axis must be performed.
