A Note From Our Technicians: Many customers ask if they can just grab a PCM from a salvage yard. While tempting, it’s a recipe for frustration. GM modules from this era are ‘locked’ to the original vehicle’s anti-theft system (VATS). Installing a used module without proper programming will result in a no-start condition every time. Our service eliminates this entire headache. By programming the module to your VIN before it ships, we ensure it communicates seamlessly with your vehicle’s other systems, making the installation process as smooth as possible.
Frequently Asked Questions
Where do I provide my VIN?
After placing your order, please include your 17-digit Vehicle Identification Number in the ‘notes’ section during checkout. You can also reply to your order confirmation email with the VIN. We cannot ship your part until we receive this information.
Is any additional programming required after installation?
Our VIN programming handles the engine and transmission calibration. However, on most GM vehicles, you will need to perform a simple security relearn procedure so the module recognizes your specific keys. This process takes about 30 minutes and does not require any special tools.
Do I need to send my old PCM (core) back?
No. There is no core charge or core return required for this part, saving you time and return shipping costs.
How do I confirm this part is correct for my vehicle?
Please match your vehicle’s year, make, and model to the compatibility list provided. The most accurate way to ensure a match is to check the service number on your original module. This Programmed 2003 S10 PCM 12570557 replaces a long list of compatible service numbers, including 12581565, 12576106, and 89017733.
What does ‘flashed with the latest GM updates’ mean?
It means we install the most current and stable version of the factory software for your specific vehicle. This can resolve drivability issues and improve performance over the original calibration that came with your truck from the factory.
What is the warranty on this part?
This unit is backed by our one-year replacement warranty.
