Condition
Some customers may comment that the 360° camera option (RPO UVS) will lose all camera views when the tailgate is removed.
This is commonly done by customers who use slide in campers or a low clearance tailgate when pulling fifth wheel trailers
Cause
The cause of the condition may be that the camera system alerts the customer to a rear camera issue by disabling all camera views if the rear camera is disabled.
Correction
Important: This repair is a costumer pay alteration.
All work and payment, authorization must come from the customer.
For customers who remove the rear tailgate for use with a slide in camper or for clearance for a 5th wheel trailer, a jumper can be installed that will provide usage of the side and front camera. The rear camera view will be blacked out. The following steps must be performed to re-enable the remaining camera views without the tailgate/camera being presently installed.
Service Procedure
Dealers can order a tailgate harness (P/N 84679989) and camera (P/N 84676845) that plug into the vehicle harness. This will provide the rear camera input that the system needs to activate the front and side cameras The camera on the jumper harness will need to have the lens blocked by black paint and electrical tape so the view will not provide a false image to the driver (see pictures).
The harness will need to be plugged into the vehicle harness, bundled and stowed under the bed with zip ties and electrical tape (see picture).
Note: When the jumper is installed the customer will not have the gridlines when in reverse and may notice an hourglass on the top corner of the screen. Below are examples of camera views with the tailgate equipped normally and tailgate removed with camera covered.
When the tailgate is reinstalled, the tailgate harness must be reinstalled and the jumper must be removed to provide 360 camera views.

service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
