Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM) is your vehicle’s main computer. It controls critical functions like fuel injection, ignition timing, and transmission shifting to ensure the engine runs efficiently and smoothly. When it fails, it can cause a wide variety of performance issues.
Is this ECM difficult to install?
For someone with basic mechanical skills, the installation is typically straightforward. The module is usually located in the engine bay and is secured with a few bolts and electrical connectors. Since we pre-program the unit, no special computer tools are needed for the installation itself. However, some vehicles may require a security or anti-theft relearn procedure, which can often be done without special tools. We recommend consulting a repair manual for your specific model.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your ECM without it. The VIN is typically found on your vehicle’s dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Will this fix my specific problem?
This ECM is a direct solution for issues caused by a faulty module. While it resolves the most common electronic engine problems, it’s essential to have your vehicle properly diagnosed to confirm the ECM is the point of failure. This part will not fix problems related to other bad sensors or mechanical issues.
What happens after I install it?
Once installed, the vehicle should start and run. As mentioned, some GM vehicles may require a simple key-relearn procedure to sync with the anti-theft system. This process is often detailed in your owner’s manual or can be found online and typically involves turning the key on and off in a specific sequence.
Is this a new part?
No, this is a high-quality, genuine used ECM that has been sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested before being programmed with the latest GM software for your vehicle, offering a reliable and affordable alternative to a new part.
