NOTE: The object used in this system check can be fabricated from 9 cm O.D. (3 in I.D.) in diameter plastic pipe 100 cm (39 in) length (available as PVC pipe, or similar from a hardware or plumbing supply).

NOTE: The following system check should be carried out with the vehicle on a level surface.

NOTE: The parking aid system will default to on when the ignition key is cycled from off to on.

Turn the ignition to the ON position, engine off.
Set the parking brake on.
Place the gear shift in reverse.
Verify that the parking aid system detects the specified object when placed within the 5 specified locations (P1, P2, P3, P4, P5). These zones are shown in the illustration ideally and are not absolute. Pipe should be inside of locations.
- The sounder should beep slowly when objects are detected on the outer edges of the detection zone, and increase as the object is moved closer to the vehicle. When the object is with in 46 cm (18 in) of the rear bumper, the sounder should be on continuously.
Using the scan tool, monitor the parking aid distance PID. The distance PID reads between 0 and 255 cm (0 and 8 ft) on a correctly functioning system.
