******GM installed this 12603530 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. We are also a 19+ year eBay member with an Excellent positive feedback score.

*******No computers are "plug and play" as described in misleading competitor ads.
Upon installation you will need to perform the security system relearn procedure (also known as +Passlock* relearn or the theft system relearn). 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 important to ensure specific vehicle programming and to guarantee flawless performance in your vehicle.

There is no core charge with this auction. This is a great opportunity to own a spare ECM. Buy now and save.
