Expert Insight: The Critical Role of VIN Programming

Our process ensures your new Programmed 2003 GMC Savana 1500 PCM is a true digital clone of your original, but with the benefit of the latest software updates. It’s the key to a successful, long-lasting repair that gets you back to work without complications.
Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, you will receive instructions to reply with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Is this part difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the module. After installation, you will need to perform a simple security relearn procedure (often called a Passlock or VATS relearn) which takes about 30 minutes and does not require special tools. We can provide instructions for this process.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM (with codes related to internal failure or communication), this part is the correct solution. However, it will not fix codes related to other failing sensors or mechanical parts. It’s crucial to properly diagnose your vehicle’s issues before ordering.
What if my original part number isn’t listed?
The part numbers listed are the most common service numbers. If your number is different, please contact us with your VIN before ordering. We can verify compatibility to ensure you receive the correct module for your vehicle.
What does the warranty cover?
This unit is backed by our one-year replacement warranty, which covers any defects in the module itself. It does not cover issues caused by improper installation or other failing parts on the vehicle.
