Restore Your Vehicle’s Brain and Get Back on the Road
Is your 2004 GM truck or SUV suffering from frustrating and intermittent issues?

Our service ensures the module provides a perfect digital handshake with your vehicle’s existing systems, just as it did when it left the factory.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
Is this really a plug-and-play part?
Yes. Because we program the PCM to your specific VIN before shipping, it will be ready to install and operate your vehicle without any additional programming or dealer intervention. In some rare cases, a security relearn procedure may be necessary, which can be done without special tools.
How can I be sure this fits my vehicle?
This PCM fits a wide variety of 2004 GM trucks and SUVs. The best way to confirm is to match the service number on your current computer to one of the numbers listed, such as 12586242, YFXP, YFKX, etc. Providing your VIN during checkout allows us to perform a final compatibility check.
Where is the PCM located on my 2004 Suburban?
On most GM trucks and full-size SUVs from this era, including the Suburban, Tahoe, and Silverado, the PCM is located in the engine bay on the driver’s side, under the battery tray or next to the airbox.
What if I order the wrong part?
We strongly encourage you to verify your part number before ordering. Because these units are programmed to a specific VIN, they are not easily returned. If you are unsure, please contact us with your VIN, and we will be happy to verify the correct part for your vehicle.
