Condition
Some customers may comment on software related issues with the CLUSTER.
Continuous improvement software updates for the INSTRUMENT CLUSTER are being
released with improvements made in several areas.
Cause
The cause of the condition may be software anomalies in the CLUSTER.
Correction
A new cluster software update, version 162.1, was released to service for vehicles
equipped with Cluster system RPO UDV only. In addition to providing general
robustness and stability enhancements, this update includes all enhancements from
previous software version releases. Along with the vehicles mentioned above, vehicles in
unconnected markets, and fleet customers may need the dealer to reprogram the
instrument cluster with the new software package.
162.1 Most Notable Improvements in the CLUSTER
Important: Improvements will vary by model, build
configuration, system, and sales region. Not all
vehicles have all features.
Most notable improvements contained in this release
may include but not limited to:
• Cluster sets U053B00 Invalid data received from
external object calculating module – Adaptive
Cruise may not function.
• Drive Mode Control Animations, Cluster - Drive
mode animations mismatch intermittently on
shutdown and may be visible to the customer.
Service Procedure
Important: Service agents must comply with all
International, Federal, State, Provincial, and/or
Local laws applicable to the activities it performs
under this bulletin, including but not limited to
handling, deploying, preparing, classifying,
packaging, marking, labeling, and shipping
dangerous goods. In the event of a conflict between
Copyright 2023 General Motors LLC. All Rights Reserved.
the procedures set forth in this bulletin and the
laws that apply to your dealership, you must follow
those applicable laws.
Caution: Before downloading the update files, be sure
the computer is connected to the internet through a
network cable (hardwired). DO NOT DOWNLOAD or
install the files wirelessly. If there is an interruption
during programming, programming failure or control
module damage may occur.
• Ensure the programming tool is equipped with the
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
Page 2

charged 12 V jumper or booster pack
disconnected from the AC voltage supply. DO
NOT connect a battery charger.
• Follow the on-screen prompts regarding ignition
power mode, but ensure that anything that drains
excessive power (exterior lights, HVAC blower
motor, etc) is off.
• Clear DTCs after programming is complete.
Clearing powertrain DTCs will set the Inspection/
Maintenance (I/M) system status indicators to NO.
Important: The service technician always needs to
verify that the VIN displayed in the TLC left side drop
down menu and the top center window match the VIN
plate of the vehicle to be programmed prior to using
Service Programming System 2 (SPS2) for
programming or reprogramming a module.
• For the TLC application, service technicians need
to always ensure that the power mode (ignition) is
“ON” before reading the VIN from the vehicle’s
VIN master module and that they do not select a
VIN that is already in the TLC application memory
from a previous vehicle.
Bulletin No.: 22-NA-253
•
If the VIN that shows up in the TLC top center
window after correctly reading the VIN from the
vehicle does not match the VIN plate of the
vehicle, manually type in the VIN characters from
the vehicle VIN plate into the TLC top center
window and use these for programming or
reprogramming the subject module with the
correct vehicle VIN and software and/or
calibrations.
• The Engine Control Module (ECM) is the master
module (for VIP vehicles) that TLC reads to
determine the VIN of the vehicle. If the VIN read
from the vehicle by TLC does not match the VIN
plate of the vehicle, the ECM also needs to be
reprogrammed with the correct VIN, software and
calibrations that match the vehicle’s VIN plate.
• The Body Control Module (BCM) is the master
module (for GEM vehicles) that TLC reads to
determine the VIN of the vehicle. If the VIN read
from the vehicle by TLC does not match the VIN
plate of the vehicle, the BCM also needs to be
reprogrammed with the correct VIN, software and
calibrations that match the vehicle’s VIN plate.
Caution: Be sure the VIN selected in the drop down
menu (1) is the same as the vehicle connected (2)
before beginning programming.

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.
