Involved vehicles are marked “Open” on the Investigate Vehicle History screen in GM Global Warranty Management
system. This site should always be checked to confirm vehicle involvement prior to beginning any required inspections
and/or repairs.
Condition

Correction

Due to the industry-wide semiconductor shortage, the side blind zone alert feature is not functional on
certain 2022 model year vehicles listed above, built beginning June 28, 2022. The affected vehicle
owners should have been made aware of the condition at sale, and notified that once parts are
available, they would be eligible for a no additional cost retrofit to enable the feature.
Dealers are to perform a configuration and setup on the instrument cluster, install side object sensing
alert modules, and replace the outside rear view mirror glass.

Important: * To avoid warranty transaction rejections, carefully read and follow the instructions below:
•

The Warranty Claim Code must be accurately entered in the “Warranty Claim Code” field of the transaction.

•

When more than one Warranty Claim Code is generated for a programming event, it is required to document all
Warranty Claim Codes in the “Correction” field on the job card. Dealers must also enter one of the codes in the
“Warranty Claim Code field of the transaction, otherwise the transaction will reject. It is best practice to enter the
FINAL code provided by SPS2.

Warranty Claim Code Information Retrieval
If the Warranty Claim Code was not recorded on the Job Card, the code can be retrieved in the SPS2 system as
follows:
1.
2.
3.
4.

Open TLC on the computer used to program the vehicle.
Select and start SPS2.
Select Settings.
Select the Warranty Claim Code tab.

The VIN, Warranty Claim Code and Date/Time will be listed on a roster of recent programming events. If the code is
retrievable, dealers should resubmit the transaction making sure to include the code in the SPS Warranty Claim Code
field.
Service Procedure
Note: The rear obstacle detection module wiring is wire tied to the brackets and the connectors have caps installed. Cut
and dispose of the wire ties and remove and discard the connector caps.
1.

Install the left and right-side obstacle detection control modules. Ensure the correct part number is installed in the
correct left-right position. Refer to Side Obstacle Detection Control Module Replacement in SI. The brackets and
fasteners are already installed on the vehicle. Only remove the rear bumper fascia enough to install the modules, it
is not necessary to completely remove the assembly. When programming the modules, only the left module requires
programming.

Important: When removing the mirror glass, rotate the wiring harness (purple and black/white circuit) electrical connector
while gently pulling on the harness. There is a step on the connector that catches on the opening and rotating the harness
will release the connector. Do not apply excessive pull to the harness, the connector will be damaged.

N222381840 Side Blind Zone Alert Retrofit
2.

Remove and discard the existing left and right outside rearview mirror glass. Refer to Outside Rearview Mirror Glass
Replacement in SI.

3.

Install the new left and right side outside rearview mirror glass. Refer to Outside Rearview Mirror Glass Replacement
in SI.

Note: Carefully read and follow the instructions below.

•

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 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.

•

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.

Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. A
copy of the customer letter is provided in this bulletin for your use in contacting customers. Program follow-up cards
should not be used for this purpose, since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this program enters your vehicle inventory or is in your facility for service
through May 31, 2026, you must take the steps necessary to be sure the program correction has been made before
selling or releasing the vehicle.

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 tools, equipment, 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 dealer for information on whether your
vehicle may benefit from the information.
