2015-16 Yukon Engine computer 12669318 ECU ECM PCM "Programmed to your VIN"

After you purchase the E.C.M. you will need to provide us with your V.I.N so that we can program the E.C.M. before we ship it to you. This computer is refurbished and tested for functionality. There is no core charge you keep your old E.C.M. There is a one year replacement warranty. **The vehicle may or may not start once the computer is installed.   If the vehicle does not start an antitheft password relearn procedure will have to be done.   Also, the vehicle may run for a period of time (weeks or months) and then will not start and may set a code P0633.   If this occurs the following procedure will have to be done so that the security password will be learned by the replacement ECM.   To avoid any inconvenience it is best to do this procedure at the time that you install the replacement ECM.   This requires a programming tool (J2534 interface tool or equivalent) and a subscription to acdelcotds****(cost to program one vehicle is $40.00)  A properly equipped auto repair shop, dealer or locksmith can do this procedure.** A crankshaft variation relearn will need to be performed once the vehicle is running. This will be evident if the check engine or service engine soon light comes on once the vehicle is running. You will need access to a scan tool capable of doing this procedure to do this and clear any related trouble codes (Code P0315). If this is not available to you a repair shop will have to perform this and clear the related trouble code. The vehicle will run normal but the ”service engine soon” light may come on and a trouble code will be stored until this is resolved. We will ship within one business day of payment. **Same day shipping if ordered by 2:00 P.M. EST (Mon-Fri).** \*\*\*If your vehicle is a flex fuel vehicle and there is any amount of E85 in the gas tank you will need to drain the tank and flush the lines first so that the new ECM can calibrate with gasoline\*\*\* **_Flashmasters does not use ACDelco Technical Delivery System (TDS) services for any module services.
