Restore Peak Performance to Your GM Truck or SUV
Is your 2004 Silverado 1500, Sierra, or Tahoe running rough, shifting erratically, or displaying a persistent check engine light?

This professionally programmed PCM is the definitive, hassle-free solution to restore your vehicle’s factory performance and get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty PCM can cause a cascade of frustrating issues. If you’re experiencing poor fuel economy, a rough or unstable idle, harsh transmission shifting, or diagnostic trouble codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (PCM Processor Fault), it’s a clear sign your vehicle’s brain needs attention. Installing this pre-programmed 2004 Silverado 1500 PCM is the most effective way to resolve these problems at their source, providing a stable and reliable fix that restores proper engine and transmission operation.

Frequently Asked Questions
Do I need to program this computer after I receive it?
No. We program the computer to your vehicle’s VIN before it ships. It will arrive ready for a plug-and-play installation. In some cases, a simple security relearn procedure may be required, which can be done without any special tools.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will receive instructions on how to send us your VIN. We cannot ship your part until we receive this information, as it is essential for programming.
How can I be sure this fits my vehicle?
This PCM is a direct replacement for service number 12586242 and many others listed in the description. As long as your vehicle is listed and your original part number matches, this will be the correct fit. We use your VIN to confirm the exact calibration needed.
Will this fix my check engine light?
If your check engine light is caused by an internal failure of the original PCM (common codes include P0601, P0602, P0606), then this part is the correct solution. However, it’s always recommended to have your vehicle properly diagnosed to ensure the PCM is the root cause of the issue.
Where is the PCM located on my 2004 Silverado?
On most 2004 GM full-size trucks and SUVs like the Silverado, Sierra, and Tahoe, the PCM is located in the engine bay, on the driver’s side, under the battery tray or next to the airbox.
