NOTICE: Paint the new sensor(s) with base coat and one coat of clear. Excessive paint film buildup may result in incorrect sensor
operation.
Using the scan tool, verify that the parking aid sensor PIDs read no object present, and that the parking aid sensor attenuation PIDs read
between 0.8-1.6 ms. If the parking aid sensor attenuation PIDs do not read between 0.8-1.6 ms, the paint is too thick on the sensor(s) and it
will be necessary to repaint the sensor(s) as required.
