Important: Techline Connect and TIS2WEB screens
shown above.
Important: If the Same Calibration/Software Warning
is noted on the TLC or SPS Summary screen, select
OK and follow on-screen instructions. The system will
generate a warranty claim code (WCC) for
documentation purposes only. Perform service
information (SI) diagnostics to determine the cause of
the condition. Use the applicable labor operation code
when submitting a warranty claim. Do NOT use the
WCC with the warranty claim submission.
Important: When programming a module in GM’s new
Vehicle Intelligence Platform, or VIP, the power mode
(ignition) needs to be off or errors may occur. This
involves the 2020 Chevrolet Corvette, Cadillac CT5 and
CT4, as well as the upcoming full-size Chevrolet, GMC,
Cadillac SUVs and Buick Envision. Serial Data
Message Authentication also needs to have the
ignition off.
Tip: Remove any customer installed USB devices from
the USB ports before inserting the USB drive
containing the software.
1. Reprogram the Instrument Cluster. Refer to P16
Instrument Cluster: Programming and Setup in SI.
2. Access the Service Programming System (SPS)
and follow the on-screen instructions.
Page 3
3. On the SPS Supported Controllers screen, select
P16 Instrument Cluster – Setup and Configuration
and follow the on-screen instructions.
• The USB File Transfer procedure requires the
use of a USB memory stick. The radio must be
on during this procedure. The USB File Transfer
procedure is not required for vehicles with UDC.
• Software currently loaded on the USB Drive will
be verified and if files are incorrect they will be
deleted and correct files will be loaded. If files
residing on the USB Drive are correct for the
vehicle being serviced, the Techline terminal
will not delete those files and allow the drive to
be re-used.
• The USB File Transfer procedure is normally
performed with the Ignition ON/Vehicle in
Service Mode. If USB File Transfer fails in
Ignition ON/Vehicle in Service Mode, attempt
USB File Transfer again with the engine
running.
Note: Setup and Configuration is not required for this
field action programming event.
4. On the SPS Supported Controllers screen, select
P16 Instrument Cluster – USB File Transfer and
follow the on-screen instructions.
5. At the end of programming, choose the “Clear All
DTCs” function on the SPS screen.

second attempt, then contact the Techline Customer
Support Center.

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.
