2012 Buick Enclave Engine Computer ECM 12643248 *VIN Programmed

**This ECM fits the following: 2012 Buick Enclave 3.6L** You must exactly match the service number 12643248 with the sticker from your Original Computer. **\*\*If the number is not an exact match it will not work\*\*** **When you order send us a message with the VIN Number** **The computer will NOT ship until we have the VIN** This is a re-manufactured unit that is tested. No core is required you keep your old unit. The computer has a 6 month warranty. If you want to avoid having to do a 30 minute relearn procedure so that your car will start as soon as you install the replacement computer, we can clone your original ECM so that you will receive a fully functioning replacement computer that will be a duplicate of your vehicle's original computer.   You must mail to us your original computer.   Your computer must still communicate so that we can transfer the data to the replacement computer, and it must not be tuner locked.   We will ship back both your original computer and the replacement computer from us. Otherwise, two things may have to be done after you install your ECM.   First an anti-theft relearn may have to be performed.   If this is the case the vehicle will not start. **Instructions will be included in the box.** This procedure requires that either a battery charger be connected to the vehicle or jumper cables be connected to another vehicle that should be left running the whole time.   On some vehicles this procedure may not work, if that is the case refer to the paragraph below. \*\*This computer may require a theft deterrent relearn that must be performed with a  programming scan tool through an online subscription with ACDelcoTDS before it will start the vehicle **(does not apply if you are cloning the ECM)**.    A dealer or properly equipped repair shop can do this (charges will vary).\*\* A crankshaft variation relearn will need to be performed once the vehicle is running **(does not apply if you are cloning the ECM)**. 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 will come on and a trouble code will be stored until this is resolved. The photo in this listing is a stock image, and will not look exactly like the computer you get. We will ship your item within 1-2 business days of receiving a cleared payment. _Module Medics does not use ACDelco Technical Delivery System (TDS) services for any module services.
