Collision Avoidance and Parking Assist Systems: Description and Operation

Park Assist Display:

Park Assist Display Location:

The Park Assist Display is located in the rear of vehicle, over the rear window in the headliner. It is a molded plastic unit housing Light Emitting Diodes (LED's) and a chime module. Located in the rear of the vehicle for easy visual reference when the driver is backing up.

The display is used to alert the driver of any obstacles detected in the rear of the vehicle. The chime or audible signal also comes from the display unit.

when the ignition is put in the RUN position, all the Light Emitting Diodes (LED's) will illuminate for approximately one second. This will be interrupted if the system senses an obstacle.

The ready status will be sensed by the outermost two yellow LED's being illuminated at 50% intensity. As the obstacle is sensed, the yellow LED's will start illuminating inward until the object is approximately 40 cm (16 in.) away and then the inner red LED will light.

The display is sensitive to which side of the rear of the vehicle that the object is detected. If on the left rear, the left segments will light and the same for the right side of the vehicle.

Correlation Of Led Segments To Distance:

There will be an audible tone when the object gets within 40 cm (16 in.) from the rear of the vehicle.

To diagnose and test the Park Assist System, use a scan tool and the appropriate diagnostic information.
