Some customers may comment that a 'Park Assist Off' message is appearing on the Driver Information center (DIC) at times.
There are several factors listed below that can cause this message to appear. A Tech 2 can be used to access the latest entry into the Park Assist Module history buffer to help determine a cause.
Inhibit Modes | Description |
|---|---|
Manual Disable | Customer disabled via On/Off switch or Vehicle Menu. |
Parking Brake | Parking brake engaged. |
Attached Object | Any object detected by the system such as a trailer, trailer hitch receiver, bike rack, or lowered tailgate. |
Reverse Overspeed | Vehicle driven in reverse gear over 8 km/h (5 mph). |
Inhibit | Loss or invalid GMLan signal(s). |
Sensor Disturbance | Ultrasonic noise from another vehicle with Park Assist, a jackhammer, or the compression of air brakes on a very large truck. |
Sensor Ring Time | Sensors are dirty, covered with snow, ice or slush, or paint on sensor membrane is too thick after a repaint. |
Engineering has received multiple inhibited Rear park Assist Modules through warranty parts return with attached object stored in the latest history buffer. If a vehicle has a trailer hitch installed into the trailer hitch receiver, it is possible for the rear park assist to be disabled. Once the trailer hitch is removed, the message should go away. Other possible causes may be dirty sensors. Keep the rear bumper free of mud, dirt, snow, ice and slush.
Important: Please note that any object that is installed in the receiver hitch, extending from the rear of the vehicle, or blocking the sensors can disable the Parking Assist, resulting in the message 'Park Assist Off'. Please remove the object or obstruction from the vehicle to re-enable the system.
This is normal operation of the system.
