Our process gives you a fully updated, VIN-matched computer that you can install in your own driveway. It’s the smartest, most efficient way to solve the problem correctly the first time.”

Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive the VIN, as the programming is specific to your exact vehicle.
Is any additional programming required after installation?
This module comes fully programmed for your engine and transmission. However, on most GM vehicles of this era, you will need to perform a simple security relearn procedure (often called a CASE relearn or anti-theft relearn). This procedure can be done without any special tools and typically involves a sequence of turning the key in the ignition. Instructions are readily available online or in service manuals.
How do I know if this part number is correct for my car?
This unit is a direct fit for the vehicles listed: 2005-2006 Cobalt, 2006 HHR, and 2005-2006 Pursuit with the specified 2.2L engine. It replaces a range of original service numbers, including 12599714, 12589998, and 12597329. Providing your VIN ensures we program and send the perfect match.
What is the difference between a PCM and an ECM?
The terms are often used interchangeably. PCM stands for Powertrain Control Module and typically controls both the engine and transmission. ECM stands for Engine Control Module. For your 2005-2006 Cobalt PCM, it functions as the central computer for the entire powertrain.
What does the one-year replacement warranty cover?
This unit is backed by our one-year replacement warranty. This covers any defects in the module itself. If the unit fails within one year of the purchase date, we will provide a replacement part.
