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
General Motors has decided to conduct a voluntary emissions recall involving certain 2019 Chevrolet
Silverado 4500HD/5500HD/6500HD vehicles equipped with a diesel engine. The engine control module
(ECM) in these vehicles does not properly diagnose malfunctions of Exhaust Gas Temperature Sensor
#5. If engine control system diagnostic tests determine that this temperature sensor is not performing
as expected, the control system becomes locked in a pending fault state. When this happens, the system
cannot illuminate the Malfunction Indicator Lamp (MIL) or clear the pending fault state, even when normal
temperature sensor performance is confirmed. While in the pending fault state, other diagnostic tests
may not run, and exhaust braking performance capability may be reduced.
Dealers are to reprogram the engine control module with modified software.
Parts
No parts are required for this repair.

•
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.
•
Turn OFF or disable systems that may put a load on the vehicles battery such as; interior lights, exterior lights
(including daytime running lights), HVAC, radio, etc.
•
Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M)
system status indicators to NO.

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 recall enters your vehicle inventory, or is in your dealership for service in
the future, you must take the steps necessary to be sure the recall correction has been made before selling or 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.
Dealer Reports
For dealers with involved vehicles, a listing with involved vehicles has been prepared and will be provided to U.S. and
Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. The listing may
contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor
vehicle registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in
several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to
complete this recall.
Customer Notification
USA & Canada - General Motors will notify customers of this recall on their vehicle (see copy of customer letter included
with this bulletin.
In order to ensure full protection under the emission warranty, and the right to participate in future recalls, the customer
notification letter recommends that customers have their vehicles serviced as soon as possible. It also advises that failure
to do so could legally be determined to be lack of proper maintenance. The vehicle may fail a state or local emission
inspection test if the recall work is not completed.
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.
In order to ensure full protection under the emission warranty, and the right to participate in future recalls, the customer
notification letter recommends that customers have their vehicles serviced as soon as possible. It also advises that failure

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.

Product Emission Recall
N192213720 Medium Duty Exhaust Gas Temperature (EGT) Sensor
Position 5 On Board Diagnostic (OBD) Performance Fault
October 2019
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 2019 Chevrolet Silverado Medium Duty 4500HD/5500HD/6500HD vehicle, equipped
with a 6.6L Diesel engine may have an engine control module (ECM) that does not properly diagnose malfunctions of
Exhaust Gas Temperature Sensor #5. If engine control system diagnostic tests determine that this temperature sensor
is not performing as expected, the control system becomes locked in a pending fault state. When this happens, the
system cannot illuminate the Malfunction Indicator Lamp (MIL) or clear the pending fault state, even when normal
temperature sensor performance is confirmed. While in the pending fault state, other diagnostic tests may not run, and
exhaust braking performance capability may be reduced. Your vehicle is equipped with an improperly functioning onboard emission-related diagnostic system that violates California and Federal standards and regulations.
What Will Be Done: Your GM dealer will reprogram the ECM with modified software. This service will be performed
for you at no charge. Eligibility for the ECM reprogramming will not be denied solely due to your vehicle having nonGM parts or repairs performed by outlets other than GM franchised dealers.
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 23 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.

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.
