Restore Peak Performance to Your 2008 GMC Savana 2500
Is your work van running rough, stalling, or displaying a persistent check engine light? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine, transmission, and emissions systems. A faulty ECM can lead to poor fuel economy, erratic shifting, and even a no-start condition, leaving you stranded and costing you valuable time. This replacement Engine Control Module, part number 12622141, is the definitive solution to get your 2008 Savana 2500 back to factory-spec operation.
Unlike generic modules that require expensive trips to the dealership for programming, this unit arrives at your door ready for installation. We take the hassle out of the repair by pre-programming the module to your van’s specific Vehicle Identification Number (VIN). This ensures that all factory settings, security information (anti-theft), and powertrain parameters are perfectly matched to your vehicle’s original configuration. The process is simple: place your order, provide us with your VIN, and we handle the complex flashing process with the latest GM-certified software updates. This means a smoother installation and a more reliable, long-term repair.

This critical step prevents compatibility conflicts that can cause even more problems than the original faulty part. By installing a module flashed with the latest GM software, you’re not just replacing a part; you’re ensuring your vehicle’s systems operate with the most current logic for optimal efficiency and performance.
This module is a direct replacement for part numbers 12622141, 12612384, and 12617568, and fits a wide array of GM trucks, vans, and SUVs from the 2008 model year and beyond. Please verify the part number and consult the detailed fitment list to confirm compatibility with your specific vehicle and engine option.
Frequently Asked Questions
Do I need to do anything after installing this ECM?
While our programming handles the engine and transmission software, you may need to perform a security relearn procedure (also known as a Passlock or anti-theft relearn). This procedure is simple, requires no special tools, and typically involves a sequence of turning the key on and off. Instructions are readily available online or in your vehicle’s service manual.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive and validate your VIN, as this is essential for the programming process.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part. Each unit is verified to be fully functional before being programmed with the latest software for your specific vehicle, ensuring reliability and perfect fitment.
Where is the ECM located on my 2008 Savana 2500 Van?
On the 2008 Savana 2500 with a gasoline engine, the Engine Control Module is typically located in the engine compartment, on the left-hand (driver’s) side, often near the rear of the engine bay. Always disconnect the battery before attempting to remove or install the module.
Will this fix my specific problem?
This module will correct issues directly caused by a faulty ECM. While the symptoms listed are common indicators of ECM failure, we always recommend a thorough diagnosis by a qualified mechanic to rule out other potential causes, such as wiring, sensor, or fuel system problems.
