Front Radar Sensor Incorrect Axial Gap (C1A11,C1A14)
DESCRIPTION
When the system determines that the vehicle is driving straight ahead based on
signals from the yaw rate and acceleration sensor (airbag sensor assembly), etc.,
the millimeter wave radar sensor assembly performs self-diagnosis to check if the
sensor beam axis is misaligned.
