Front Radar Sensor Incorrect Axial Gap (C1A11)
DESCRIPTION
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.
If the millimeter wave radar sens ...
