Condition

Correction

General Motors has decided to conduct a Voluntary Emission Recall on certain 2015-2016 model year
Chevrolet Silverado HD and GMC Sierra HD vehicles equipped with a 6.6L diesel (LML) engine and
dual fuel tanks (N2N). Under certain driving conditions, fuel may not be transferred from the rear fuel
tank to the front fuel tank at a sufficient rate. If this occurs, the diagnostic trouble code (DTC) P2636
will set, the malfunction indicator lamp will illuminate, the fuel gauge will display empty, and the transfer
pump will be disabled until serviced. If the vehicle continues to be driven, it will run out of fuel in the
front tank and stall.
Dealers are to replace fuel line connections to allow the rear tank, in addition to the front tank, to directly
supply fuel to the engine. The engine control module (ECM) will also be reprogrammed with calibrations
necessary to support this new connection.

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.
