Expert Insight: The Critical Role of Correct Programming
As a technician with over two decades of experience, I’ve seen countless vehicle issues caused by improperly matched control modules. Simply installing a used computer from another vehicle is a recipe for disaster. Systems like the anti-theft (Passlock/VATS), transmission controls, and emissions equipment will not function correctly. Our process eliminates that risk. By programming the module to your exact VIN, we ensure it has the correct software, calibrations, and security information to integrate seamlessly with your vehicle. This is the ‘get it right the first time’ approach that saves you from headaches and additional diagnostic costs down the road.
Don’t let a faulty computer keep your vehicle off the road. This Programmed 12570558 PCM is the most dependable and efficient way to restore your GM vehicle’s brainpower. After your purchase, simply provide us with your VIN, and we’ll handle the complex programming so you can focus on the simple installation.
Frequently Asked Questions
What exactly does a PCM do?
The Powertrain Control Module, or PCM, is the central computer of your vehicle. It controls all aspects of the engine and transmission, including fuel injection, ignition timing, emissions systems, and shift points, to ensure optimal performance, fuel efficiency, and reliability.
How does the VIN programming process work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. We use this number to access the official GM database and load the exact software and calibrations that your specific vehicle requires. The module arrives at your door ready to be installed with no further programming needed.
Do I need to perform a security relearn procedure after installation?
In most cases with GM’s Passlock/VATS security systems of this era, a simple security relearn procedure is required after installation. This process typically takes about 30 minutes and involves cycling the ignition key. It does not require any special tools, and we can provide instructions if needed.
Is this the correct part for my truck/van?
This module is compatible with a wide range of GM vehicles listed in the compatibility chart. The best way to confirm fitment is to match the service number on your original module to one of the numbers listed (e.g., 12570558, 12581565, etc.). Providing your VIN during the programming step serves as a final verification.
What if I order the wrong part?
We strongly encourage you to verify the part number on your existing module before ordering. Because this is a custom-programmed electronic part, it’s crucial to ensure compatibility first. If you have any doubts, please contact us with your VIN, and we’ll be happy to help you confirm the correct part for your vehicle.
