Grand Prix 2005 3.8L Engine Computer PCM ECM 12591278 - Programmed to your VIN #

 We can't ship your computer until we receive your 17 digit VIN.**** ****\*\*\*\*\*\*GM installed this 12591278 PCM in the above application as well as several other GM models.  This was possible because each of these models received their specific programming from the factory.   In other words, you can't simply swap a used PCM from one vehicle to the next.** **With your purchase, we will** **program** **the PCM to your VIN (vehicle identification number) with matching software.**** ****\*\*\*\*\*\*This PCM is used and was removed from a running salvaged vehicle.   This PCM comes with a 1-year** **replacement guarantee** **.   We have been in the PCM business for 16+ years.  The security relearn is an on vehicle relearn to your specific vehicle and is what allows the vehicle to accept the replacement computer and start the vehicle.  It is an on vehicle relearn so it is not something that can be programmed outside the vehicle. It doesn't require any special tools and is essentially turning the ignition key on and off in a sequence.  I supply you with the step by step instructions on how to complete this.**** **Once the vehicle starts you would need to complete any other on vehicle relearn procedures necessary for your vehicle. This may include but not limited to an idle relearn, drive cycle relearn, or CKP relearn(crank position relearn P0315/ / P1336).  The CKP relearn requires the use of a shop level scan tool.** ****If you are not clear on the complete removal and installation process for the computer for your vehicle please check the service repair manual for your vehicle or allow a certified technician to install the computer for you** **.**** **Other info:** **Why buy your spare PCM from us?You will be purchasing a high quality used PCM.You get free Flash programming with your purchase.
