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 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, replace the front HVAC user interface control
module and reprogram the body control module. In addition, Traverse vehicles will require the HVAC
control module programming and some Silverado HD and Sierra HD vehicles may require replacement
of the AM/FM stereo radio control.

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).
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.

Service Procedure
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.
IMPORTANT: FOR SILVERADO AND SIERRA ONLY - MULTIPLE PART NUMBERS MAY SHOW IN THE
ELECTRONIC PARTS CATALOG. ORDER THE PART THAT DOES NOT INCLUDE RPO 00V IN THE USAGE
COLUMN IN THE EPC.
2.

Record the serial number of the new seat heater vent control module (see instructions above).

3.

Install the new service front seat heater vent control module. Refer to Front Seat Heater Vent Control Module
Replacement in SI.

4.

Sierra HD and Silverado HD Only. In order to replace the heater and air-conditioning user interface control, it is
first necessary to install the correct radio control assembly. Refer to Radio Control Assembly Replacement in SI.

5.

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.

or ownership, through November 30, 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 November 30, 2025, you must take the steps necessary to be sure the program correction has been made before
selling or releasing the vehicle.
