Condition

Correction

General Motors has decided to conduct a Voluntary Emissions Recall on certain 2022 Chevrolet Malibu
vehicles with a 1.5L engine. It is possible the Engine Control Module (ECM) in these vehicles could set
a Diagnostic Trouble Code (DTC) for the engine’s high pressure fuel pump when there is no actual
malfunction. If this were to occur, the vehicle could be unnecessarily placed into a reduced engine power
mode.
Dealers are to reprogram the ECM.

Parts
No parts are required for this repair.

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
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 the procedures set forth in this bulletin and the laws that apply to your dealership, you must follow
those applicable laws.

Coordination Incorrect Breakpoint
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 recall 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, dealer-traded,
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 recall at no charge to customers, regardless of mileage, age of vehicle,
or ownership, from this time forward.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer
information indicated on the dealer 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. Recall 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 field action enters your vehicle inventory you must take the steps
necessary to ensure the program correction has been made before selling the vehicle. In addition, for vehicles entering
your facility for service, you are required to ensure the customer is aware of the open field action and make every
reasonable effort to implement the program correction as set forth in this bulletin prior to releasing the vehicle.
***THE FOLLOWING 2 PARAGRAPHS ARE NOT FOR CANADA OR EXPORT***
When a California emissions recall is completed by a GM dealer, the dealer must provide the vehicle owner a “Proof of
Correction Certificate” which the owner may need to present to the California Department Of Motor Vehicles (DMV) when
renewing their vehicle registration. Without this correction certificate, the owner may be unable to renew their vehicle
registration.
Additional Certificates can be obtained, at no charge, from the 1Store application in GlobalConnect. Request GM Item
Number 1825 when ordering.

August 2022
This notice applies to your vehicle, VIN: _____________________________________
Dear General Motors Customer:
This notice is sent to inform you that General Motors is conducting a voluntary emission recall that includes your
vehicle.
Reason For This Recall: Your 2022 model year Chevrolet Malibu vehicle, equipped with a 1.5 Liter 4 Cylinder engine,
may be equipped with an improperly functioning on-board emission-related diagnostic system that violates California
and Federal standards and regulations. It is possible the Engine Control Module (ECM) in these vehicles could set a
Diagnostic Trouble Code (DTC) for the engine’s high pressure fuel pump when there is no actual malfunction. If this
were to occur, the vehicle could be unnecessarily placed into a reduced engine power mode.
What Will Be Done: Your GM dealer will reprogram the ECM. This service will be performed for you at no charge.
Eligibility for this service will not be denied solely due to your Chevrolet Malibu vehicle having non-GM parts or repairs
performed by outlets other than a GM franchised dealer.
How Long Will The Repair Take? Because of service scheduling requirements, it is likely that your dealer will need
your vehicle longer than the actual service correction time of approximately 35 minutes.
What You Should Do: Please contact your GM dealer as soon as possible to arrange a service date. Instructions for
making this correction have been sent to your dealer. Please ask your dealer if you wish to know how much time will be
needed to schedule, process, and repair your vehicle.
If you have any questions or need any assistance, just contact your dealer or the appropriate Customer Assistance
Center at the number listed below.
For the hearing or speech impaired, please contact our Customer Assistance Center using the Telecommunication
Relay Service by dialing 711 then providing the appropriate Customer Assistance Center number for your vehicle.

Emission Law Information: In order to ensure your full protection under the emission warranty made applicable to
your vehicle by state and federal law, and your right to participate in future recalls, it is recommended that you have
your vehicle serviced as soon as possible. Failure to do so could legally be determined to be lack of proper
maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection if this recall is not
accomplished.
IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS
The California Air Resources Board (CARB) requires vehicle emission recalls be completed prior to California
registration renewal. Uncorrected emission recalls will result in the inability to renew your California vehicle registration.
At the time of emission recall completion, your California dealer will issue a "Proof of Correction Certificate". Keep this
certificate and, if required, present it to the Department of Motor Vehicles when renewing your California registration as
proof of recall completion.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued
satisfaction with our products.
