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 swapping a used computer from another vehicle will almost never work. Modern vehicles use a complex communication network (CAN bus) where every module is coded to the original VIN. Our VIN programming service isn’t just a convenience; it’s a critical step that ensures the PCM can properly control the engine, communicate with the transmission, and integrate with the anti-theft and ABS systems. Ordering a Programmed 12570558 PCM from us eliminates these compatibility headaches and ensures your repair is done right the first time.
Frequently Asked Questions
What information do you need from me?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module correctly before shipping.
Is this part truly ‘plug and play’?
Yes. Because we program the module to your VIN, it is ready for installation upon arrival. In most cases, no further programming is required. However, some vehicles may require a simple security relearn procedure, which can be done without special tools and typically takes 10-15 minutes. Instructions can be easily found online for your specific model.
My old part has a different service number on it. Will this work?
Yes. Part number 12570558 is the base number, but GM uses many different service numbers for the same hardware. This module is a direct replacement for all the compatible service numbers listed in the description, including 12581565, 12570557, 89017733, and others.
Where is the PCM located on my vehicle?
On most trucks and SUVs like the Suburban, Silverado, and Sierra, the PCM is located in the engine bay, on the driver’s side, often under or near the battery tray. On Express and Savana vans, it is typically found in the rear of the engine compartment on the driver’s side.
How do I find my VIN?
Your VIN can be found on a metal plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
