Condition
Some customers may comment on an intermittent blank or flickering Driver Information
Center (DIC) display. They may also note that this only seems to occur when playing
songs via iHeart or Pandora.
Cause
The cause of the condition may be an instrument panel software concern.
Correction
If this concern is reported, check for DTCs. If DTCs are present, this bulletin does not
apply and normal SI diagnosis should be followed. If no DTCs are present, this is the only
concern, and it occurs intermittently, do not replace any parts. Reprogram the
P16 Instrument Cluster.
Service Procedure
Refer to P16 Instrument Cluster: Programming and
Setup in SI.
Note: Please ensure all steps of P16 Instrument
Cluster: Programming and Setup in SI are performed
including USB programming. For UDD clusters on
impacted vehicles, USB programming is performed
through the USB ports accessible in the center console.

Note: Stable battery voltage is critical during
programming. Any fluctuation, spiking, over voltage or
loss of voltage will interrupt programming. Install a GM
Authorized Programming Support Tool to maintain
system voltage. Refer to www.gmdesolutions.com for
further information. If not available, connect a fully
charged 12 V jumper or booster pack disconnected
from the AC voltage supply. DO NOT connect a battery
charger.

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.
