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.

HINT:
Using the Techstream to read the Data List allows the values or states of switches,
sensors, actuators and other items to be read without removing any parts. This non-intrusive
inspection can be very useful because intermittent conditions or signals ...
