DESCRIPTION The forward recognition camera uses the millimeter wave radar sensor assembly to detect obstacles in front of the vehicle. When the vehicle is determined to be driving in a straight line or on a gradual curve based on signals from the yaw rate sensor etc., the millimeter wave radar sensor assembly performs self diagnosis to check if the sensor beam axis has deviated from the vehicle movement direction. When the millimeter wave radar sensor assembly beam axis has deviated, the forward recognition camera detects this, and 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 front camera system, perform troubleshooting for the pre-collision system. Click here
