**This listing is for one 12605843 ECM (also known as Engine Computer, Powertrain Control Module, PCM, ECU, and VCM) that will arrive at your door ready to install with the proper calibration programmed to your specific vehicle. **\*\*\*\*\*\*GM installed this 12605843** **ECM** **in all of the above applications.** **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** **ECM** **from one vehicle to the next.** **With your purchase, we will** **program** **the** **ECM** **to your VIN (vehicle identification number) with matching software so it is ready to install.** ****\*\*\*\*\*\*This** **ECM** **is used and was removed from a running salvaged vehicle.   This** **ECM** **comes with a 1-year** **replacement guarantee** **.   We have been in the** **ECM** **business for 19+ 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 ECM from us?You will be purchasing a high quality used ECM.You get free Flash programming with your purchase. OBDII type computers have the “chip” embedded into the ECM and it is not removable.The calibration file per the application is “Flashed,” or reprogrammed using a software package and a pass through device.The “chip” is no longer removed for programming.Proper programming is essential when replacing a ECM whether it is a new, used or remanufactured ECM.A used GM computer will have the software installed that pertains to the original vehicle that it was removed from.In some cases, GM OBDII type computers will interchange with many different vehicles including those with different engine and transmission configurations.However, unless the computer is programmed with the correct software it won’t function properly upon installation.We will flash program the computer purchased from us with your specific VIN number with matching software for a correct match to your vehicle.   This is a great opportunity to own a spare ECM.   Buy now and save.** **\*The picture is of a representative of the 12605843 from our inventory.   Item will be of like finish guaranteed.** +Passlock is a registered trade mark of GM Corporation.  We are not associated in any way with GM Corporation.
