Is Your 2008 Silverado Running Rough?
If you’re experiencing frustrating issues like a persistent check engine light, poor fuel economy, stalling, or erratic engine behavior, the problem might be the very brain of your truck’s engine: the Engine Control Module (ECM). The ECM is the central command center, responsible for managing everything from fuel injection and ignition timing to transmission shifts and emissions control. When it fails, the performance and reliability of your Silverado 1500 can be severely compromised.
Don’t let a faulty computer keep your truck off the road. This is a direct-fit replacement Engine Control Module for your 2008 Chevrolet Silverado 1500, part number 12612384. The most significant benefit we offer is that this module arrives at your door fully programmed with the latest GM software updates, specifically matched to your truck’s unique Vehicle Identification Number (VIN). This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
Common Symptoms of a Failing ECM
- โ Check Engine Light is on with various, often inconsistent, trouble codes.
- โ Engine stalling, stumbling, or misfiring for no apparent reason.
- โ Noticeable decrease in fuel efficiency.
- โ Difficulty starting the engine, or the engine won’t start at all.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive an email with instructions. You can simply reply to that email with your 17-digit VIN, or include it in the ‘notes to seller’ section during checkout. We cannot ship your part until we receive the VIN.
Is this ECM difficult to install?
Installation is straightforward for someone with basic mechanical skills. The ECM is typically located in the engine bay under the battery tray. You will need to disconnect the battery, unplug the electrical connectors, and unbolt the module. Since our module is pre-programmed, no special tools are needed for the electronic setup.
Will I need to perform a security relearn procedure?
In many cases, yes. Most GM vehicles of this era require a security relearn (also known as a CASE relearn or Passlock relearn) after the ECM is replaced. This procedure can typically be done without a scan tool and involves a sequence of key cycles. We include instructions for this simple process with your order.
What if my original part number is different?
This module is a direct replacement for part numbers 12612384, 12622141, and 12617568. As long as your original module is one of these numbers and your vehicle is on the fitment list, this part will function correctly once programmed to your VIN.
Is this a new or used part?
This is a high-quality, tested, and inspected used OEM part. Each module is thoroughly checked for functionality before being programmed with the latest GM software for your specific vehicle, ensuring reliability and proper operation.
