from GM Customer Care and Aftersales. The
calibration numbers required for this update
procedure are programmed into control modules
via a Multiple Diagnostic Interface (MDI) with the
calibration update. If you cannot access the
calibration, call the Techline Customer Support
Center and it will be provided.
DO NOT program a control module unless
directed to by a service procedure or a service
bulletin. If the control module is not properly
configured with the correct calibration software,

latest software and is securely connected to the
data link connector. If there is an interruption
during programming, programming failure or
control module damage may occur.

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.

on the vehicles battery such as; interior lights,
exterior lights (including daytime running lights),
HVAC, radio, etc.
• During the programming procedure, follow the
SPS prompts for the correct ignition switch
position.
• Refer to Radio Programming and Setup for
additional information on programming.
Important: For every vehicle that needs to be updated
through USB, be sure to download the files through
TIS2WEB on a USB drive each time for each vehicle.
DO NOT use the same files downloaded from a
previous vehicle. Use a USB 3.0 drive formatted to
FAT32 with a minimum size of 4 gigabytes, however,
16 gigabytes is preferable.
Important: Before downloading the USB update files,
be sure the computer is connected to the internet
through a network cable (hardwired). DO NOT

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.
