DESCRIPTION The driving support ECU assembly uses the millimeter wave radar sensor assembly to detect objects in front of the vehicle. When it is determined that the vehicle is being driven in a straight line or on a gradual curve based on signals from the yaw rate sensor, the millimeter wave radar sensor assembly performs self-diagnosis to check if the sensor beam axis has deviated. When the millimeter wave radar sensor assembly beam axis is misaligned, the driving support ECU assembly stores DTC C1A11. After installing a new millimeter wave radar sensor assembly, if sensor beam axis adjustment is not performed, DTC C1A14 is stored.
PROCEDURE
HINT: If DTC C1A11 or C1A14 is output by the dynamic radar cruise control system, perform troubleshooting for the pre-collision system. Click here
