Is Your Car Running Rough? It Could Be The Brains of the Operation.
If you’re dealing with a frustrating check engine light, poor fuel economy, stalling, or a no-start condition in your GM vehicle, the problem often traces back to a failing Engine Control Module (ECM).

You need a solution that is reliable, straightforward, and doesn’t require expensive dealership programming. This is the definitive fix you’ve been looking for.

Expert Diagnostic Tip
From over 20 years of experience, I’ve seen countless cases where these 2.2L GM vehicles exhibit strange, intermittent electrical issues that are nearly impossible to track down. The culprit is often a failing ECM with internal circuit board issues that don’t always set a clear trouble code. Mechanics can spend hours chasing phantom sensor faults, replacing perfectly good parts. Installing a known-good, correctly programmed 2002 Grand Am ECM 12210553 not only fixes the root cause but can save you hundreds of dollars in wasted diagnostic time and unnecessary parts.
Frequently Asked Questions
Do I need to program this module?
No. The main benefit of our service is that we program the ECM for you before shipping. All you need to do is provide us with your vehicle’s VIN at checkout, and the module will arrive ready to install.
What information do you need from me?
We only need your 17-digit Vehicle Identification Number (VIN). This allows us to load the exact correct software and calibrations for your car’s specific options and emissions.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then this part will resolve the issue. It’s crucial to ensure your vehicle has been properly diagnosed, as the light can be triggered by many other components. This module will fix all internal ECM-related fault codes.
Is a security relearn procedure required after installation?
Yes, but it’s simple and requires no special tools. On most of these GM vehicles, you can perform the security relearn by turning the key to the ‘ON’ position for 10-15 minutes, then turning it off, and then starting the car. We include simple, clear instructions to guide you through this process.
How do I confirm this is the right part number for my car?
The best way is to check the part number on your original ECM. This module, part number 12210553, is a direct replacement for several service numbers including 12218883, DBCM, DBCY, and more as listed in the compatibility chart. If your vehicle and engine match our fitment list, this is the correct part.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers any defects in the module itself. We stand behind our programming and the quality of our components to give you confidence in your repair.
