To:
All General Motors Dealers
This bulletin has been revised to update the correction statement, add
additional labor codes, and update the parts information section and
procedure. This has been done to accommodate a small number of vehicles
that may require the heater and air conditioning user interface control. Please
discard all copies of bulletin N212354520-03.
Please hold all warranty transactions for these new labor codes until
December 21, 2022.
Part availability for the 2022 model year Buick Envision is still limited at this
time. However, a portion of the impacted VINs have been moved to an Open
status. The Open VINs are prioritized by cold weather region. It is imperative
that IVH is verified prior to performing repairs. We estimate the remaining
2022 model year Buick Envisions will be eligible in Q1 of 2023.
N212354520-04 retrofits vehicles that require parts and programming for the
front heated/ventilated seats or front-heated seats.
Due to limited initial parts availability, dealers should not order parts included
in this field action for use as shelf stock. Parts should only be ordered when
the dealer has confirmed and validated the customer has a scheduled
appointment with the service department. Specific VINS will be required to
determine the correct part to order in the Electronic Parts Catalog (EPC).
The Heated Vented Seat retrofit will be executed under six separate bulletins
(N212354520 to N212354525). Please see chart below.
•
The six bulletins are separated by the parts and programming required
by trim level and model.
•
•
•
Based on parts availability, some of the six bulletins will launch in
phases by model.
Each VIN requiring a Heated Vented Seat retrofit will be included in one
of the six bulletins.
It is critical to verify the VIN in IVH to confirm the correct retrofit bulletin
is followed prior to ordering parts or performing repairs.

Description
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 front heated/ventilated seats, front heated seats,
or rear heated seats are not functional on certain 2022-2023 model year vehicles listed above, built
beginning November 15, 2021. 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 replace the front seat heater control module, reprogram the body control module and on
some vehicles, reprogram the HVAC control module and heater and air conditioning user interface
control. Note: Some vehicles may also require an additional retrofit of the Left and Right Front Seat
Cushion Ventilation Blower in order to restore full functionality of the ventilated seats. Vehicles built
with this condition can be identified by RPO 04O. Use IVH to verify if the vehicle is currently eligible in
the Front Seat Cushion Vent Blowers Retrofit bulletin N222378560. If so, both retrofits should be
performed at the same time.

N212354520 Heated Vented Seats Retrofit - Front Seats Only
Important: * To avoid warranty transaction rejections, carefully read and follow the instructions below:
6125814
•
The Warranty Claim Code from the programming event 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
6125774
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 (1).
Select the Warranty Claim Code tab (2).
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.
Required - Front Seat Heater Vent Control Module Serial Number Recording for all markets except Canada, US,
and Mexico
IMPORTANT: * (TECHNICIAN and WARRANTY ADMINISTRATOR) SERIAL NUMBER
RECORDING REQUIREMENT. The replacement Front Seat Heater Vent Control Module serial numbers must be
captured by the technician and recorded on the job card. The Warranty Administrator MUST enter the replacement
Front Seat Heater Vent Control Module serial numbers in GWM (Global Warranty Management) or in DMS (Dealer
Management System). Enter the serial number of the replacement Front Seat Heater Vent Control Modules in the
‘General Comments’ comments section. Failure to enter this serial number will cause the claim to reject.

5906148
Required – Front Seat Heater Vent Control Module Number Recording for Canada, US, and Mexico
The replacement front seat heater vent control module requires the serial number be recorded. A new process called
Replacement Part Traceability (RPT) is being used with this retrofit/Cust Satisfaction Program.
Overview of RPT
Replacement Part Traceability (RPT) is a new dealer process to document and track critical part serial numbers via the
Certified Service Mobile Toolbox (CSMT) application. A field action, service bulletin, or other communication will be issued
any time there is a request for technicians to complete an RPT submission. Only critical parts will require an RPT, not
every part replacement.
Submitting an RPT request is done using the RPT tool within the CSMT app. Technicians simply scan the VIN of the
vehicle and the traceability barcode (barcode or QR code) of the new part being installed on the vehicle. Once scanned,
the information is submitted through the CSMT app and stored in a GM database. That’s the end of the process.
The free CSMT app, which also includes the Field Product Reporting and Pre-Repair Authorization tools, is available on
the Google Play Store (Android devices) and the App Store (Apple devices).
Page 4 of 10
Customer Satisfaction Program
N212354520 Heated Vented Seats Retrofit - Front Seats Only
By scanning critical part numbers using the Replacement Part Traceability function, GM will be able to reference replaced
parts in the future. The exact parts that are on a vehicle will be known, even after a service part replacement.
The RPT process also simplifies the repair and claim submission processes. It eliminates the need of having technicians
write down the 16-character serial number on the job card and for warranty administrators to input the serial number into
GWM or DMS.
Refer to TSB 22-NA-070 for specific information on downloading the App to your mobile phone, how to use/submit the
new part serial number/QR code information and other related Q and A.
IMPORTANT: A new version (3.6) of the Certified Service Mobile Toolbox (CSMT) app for Replacement Part
Traceability (RPT) will be available to download on August 8, 2022. This update includes enhanced QR/barcode
scanning functionality and minor bug fixes. If you do not have your device programmed to automatically update apps,
you must download the latest version no later than August 22, 2022. All users must perform this update to be able to
continue to use the tools provided in the application.
HOW TO CHECK THE VERSION OF YOUR OPERATING SYSTEM
•
•
Apple: Settings/General/About/Software Version
Android: Settings/About Phone/Software Information/Android Version
6098077
If the App is already loaded to your phone, simply:
1.
2.
3.
Scan the VIN (door pillar QR code or windshield VIN barcode) and
Scan the new part (QR code) and
Check the information and if correct then, Submit.
Failure to submit this serial number by RPT may cause the claim to reject.
Service Procedure
Important: Some vehicles may also require an additional retrofit of the Left and Right Front Seat Cushion
Ventilation Blower in order to restore full functionality of the ventilated seats. Vehicles built with this condition
can be identified by RPO 04O. Use IVH to verify if the vehicle is currently eligible in the Front Seat Cushion
Vent Blowers Retrofit bulletin N222378560. If so, both retrofits should be performed at the same time.
1.
Remove the existing front seat heater vent control module. Refer to Front Seat Heater Vent Control Module
Replacement in SI. Discard the remove module.
Warning: To avoid potential personal injury and/or part damage, the Electronic Parts Catalog (EPC) and VIN
MUST BE USED to order the correct part.
2.
Record the serial number of the new seat heater vent control module (see instructions above).
Page 5 of 10
Customer Satisfaction Program
N212354520 Heated Vented Seats Retrofit - Front Seats Only
3.
Install the new service front seat heater vent control module. Refer to Front Seat Heater Vent Control Module
Replacement in SI.
4.
If required, replace the heater and air-conditioning user interface control. Refer to Heater and Air Conditioning User
Interface Control 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.

Dealer Responsibility
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers' possession
and subject to this program must be held and inspected/repaired per the service procedure of this bulletin before
customers take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealertraded, released to auction, used for demonstration, or any other purpose.
All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System
(CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting
an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified
for sale within the CPOIS system, or once again be used in the CTP program.
Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle,
or ownership, through December 31, 2025. Customers who have recently purchased vehicles sold from your vehicle
inventory, and for which there is no customer information indicated on the involved vehicle listing, are to be contacted by
the dealer. 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 followup 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 December 31, 2025, you must take the steps necessary to be sure the program correction has been made before
selling or releasing the vehicle.
Dealer Reports – For USA & Export
For dealers with involved vehicles, a listing has been prepared and will be available through GM GlobalConnect Maxis
Field Action Reports or sent directly to export dealers. The Inventory tab of the dealer reports will contain VINs that
apply to this field action. This information is intended to assist dealers with the PROMPT COMPLETION of these
vehicles. The Customer In-Service tab will contain customer names and addresses from Motor Vehicle Registration
Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete
this field action may be a violation of law in several states.
Courtesy Transportation – For USA & Canada
Courtesy transportation is available for customers whose vehicles are involved in a product program and still within the
warranty coverage period. See General Motors Service Policies and Procedures Manual for courtesy transportation
program details.
Customer Notification
USA & Canada - General Motors will notify customers of this program on their vehicle (see copy of customer letter included
with this bulletin).
Export - Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor
Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample letter.
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.
