Frequently Asked Questions
What information do you need from me after I order?
After you complete your purchase, we will need your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module with the correct GM software for your truck’s specific configuration.
Is this part difficult to install?
This PCM is designed for a straightforward installation. It is located under the battery on the driver’s side. While it is a plug-and-play unit, we always recommend disconnecting the battery before starting. In some cases, a simple security relearn procedure may be required, which can be done without special tools.
Will this computer fix my check engine light?
This module will correct issues directly caused by a failing PCM, including many communication codes and processor-related faults. However, it’s crucial to ensure your vehicle’s problem has been properly diagnosed. This part will not fix issues related to faulty sensors, wiring, or other mechanical components.
How does the VIN programming process work?
We use your VIN to access the official GM database and retrieve the exact calibration file for your truck. This file is then loaded onto the module, ensuring it controls the engine, transmission, and all related systems precisely as the factory intended.
Does this 2004 Silverado 2500 PCM 12586242 fit other vehicles?
Yes, absolutely. This PCM is a common module used across a wide range of 2004 GM trucks and SUVs, including the Sierra, Tahoe, Suburban, Yukon, Escalade, Hummer H2, and others. The key is to match the service number (like 12586242) to ensure compatibility.
