Condition
Some customers may comment that the RSI screens power off, coinciding with the
closing of a door or liftgate with the fob outside the vehicle and intermittently when the fob
is inside the vehicle.
Cause
The cause of the condition may be that the RSI is powered by the iRAP feed. When the
vehicle’s PEPs module searches for the key transmitter, it momentarily powers down the
iRAP feed to clear possible radio frequency interference. This causes the RSI screens to
power off.
Correction
This condition is normal operation and is described in the Rear Seat Infotainment owner’s
manual, page 5. To mitigate the concern, refer to the steps below.
• On some vehicles with push button start (keyless ignition), if you turn on the headrest
monitor, and then close all doors/ hatch while standing outside the vehicle with the
remote keyless entry/ignition FOB in your possession, the monitor will shut off. To
avoid this issue, leave a door ajar until the driver takes the FOB back inside the
vehicle.
• On some vehicles with push button start (keyless ignition) AND a wireless charging
system, if you turn on the headrest monitor, and remain in the vehicle with the remote
keyless entry/ignition FOB in your possession, the monitor will shut off if it is close to
the wireless charger upon closing of all doors/ hatch. To avoid this issue, keep the
FOB away from the wireless charging system.

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.
