Involved Region or Country
North America and N.A. Export Regions
Additional Options (RPOs)
Equipped with RPO UVC and any of the model/RPO combinations in the table above.
Condition
Some customers may report that the Rear View Camera (RVC) guidelines are temporarily
not available at times but the RVC will remain on during the concern. Additionally, no
related DTCs will be found if this bulletin applies. One example of when this concern may
be observed is if a customer quickly starts the car and immediately places the shifter in
Reverse while the infotainment system is still in the initial boot up process.
Cause
This is a result of the RVC image being provided via an alternate robust RVC feed from
the Video Bypass Module (NGI systems) or from the radio (BYOM2 and Info 3.0
systems). This alternate robust RVC feed is provided in the event that the primary RVC
feed is not available for any reason just to ensure that the RVC image is always present
when in reverse.
Correction
If this concern is experienced and no related codes are present, DO NOT replace any
parts as it is normal for the RVC guidelines not to be present when the RVC image being
displayed is from the alternate robust RVC feed. If this occurs after quickly starting the
vehicle and immediately placing the shifter in Drive, the RVC guidelines can be displayed
again in most cases if they are really needed by safely coming to a stop, placing the
transmission in Park for a moment, and then shifting to Reverse again.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
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
information.
