Ground reflection verification and sensor coverage pattern.
The parking aid system must be checked to assure that the system does not see signals from ground reflections.
The following system check should be carried out with the vehicle on a 4.8 metres wide by 3.00 metres deep smooth concrete surface, free of all obstacles. The area should be free of noise from fans and pneumatic tools.
Turn the ignition switch to position II.
Apply the parking brake.
Place the gear shift in reverse.
NOTE:No audible tones should be heard. If audible alerts are heard, check to make sure the bumper is properly installed and is not tilted downward so the sensor is pointing toward the ground.
