Subject: N222375790 - Customer Satisfaction Program
Park Assist Retrofit
Models: 2022 – 2023 Chevrolet Corvette
To:
All General Motors Dealers
General Motors is pleased to announce the first phase of the Park Assist
retrofit process and is releasing Customer Satisfaction Program N222375790
today. The total number of U.S. vehicles involved is 7,101. Please see the
attached bulletin for details.
As parts become available for additional makes and models involved in this
retrofit, we will communicate the revised bulletin in an upcoming message.
PART ORDERING INFORMATION
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.
Dealers will need to place orders CSO (Customer Service Order) and upgrade
to a SPAC, all CSO without a SPAC will be cancelled daily. All orders will
require a unique VIN for each order. If a VIN is not provided with the order, or
has already been used, those orders will be cancelled. This change in process
is due to limited parts availability and to assure we have ample stock for
customers requiring the retrofit.
The Park Assist Retrofit will be executed under 2 separate bulletins:
N222375790 will cover Vehicle Intelligence Platform (VIP) Electrical
Architecture
N222375791 will cover Global A Electrical Architecture
The remaining retrofit Customer Satisfaction Programs, beyond the Park
Assist Retrofit, will occur in phases over the next several months once parts
become available. You will receive notification when they begin.
Customer Letter Mailing
The customer letter mailing will begin mid-March 2023.
Global Warranty Management (GWM)
The Required Field Action section on the Investigate Vehicle History (IVH) screen will
be updated February 22, 2023. A Stock VIN list is not included as our records show
there are no vehicles in dealer new inventory. Please hold all warranty transactions
until IVH has been updated.

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 park assist feature is not functional on certain 2022
and 2023 model year vehicles listed above, built beginning December 2, 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 park assist control module and setup the serial data gateway module to restore
the Park Assist feature.

Parts required to complete this recall are to be obtained from General Motors Customer Care and Aftersales (GMCCA).
Please refer to your “involved vehicles listing” before ordering parts. Parts for this Retrofit will be on Order Writing control
initially and all DRO’s (Daily Replenishment Orders) may cancel. Dealers should place orders CSO (Customer Special
Order) and upgrade to SPAC with a VIN. All orders will be reviewed prior to being filled. All CSO may be cancelled
daily. Only SPAC orders with a valid VIN associated with the vehicle listing will be released while on the order
writing control. Due to order writing control orders will not ship as OVN. Please take this into consideration in
shipping if not coming from your Admin PDC.
Reminder: Parts will be removed from SPRINT, they are non-returnable and may be removed from Retail Inventory
Management (RIM). Dealers should review the affected parts to confirm RIM managed status. Parts may have quantity
limiters in effect.
For Export: Please contact CCA’s Export Order Fulfillment group to place the order on your behalf.

•
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.
Service Procedure
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.
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 March 31, 2026. 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 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 March 31, 2026, 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.
