Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we receive this information, as the programming is essential for it to work in your car.
Is this part difficult to install?
For someone with basic mechanical skills, installation is straightforward. The ECM is typically located in the engine bay or under the dash. After swapping the part, you will need to perform a simple security relearn procedure (often called a ‘key-on/key-off’ procedure) which takes about 30 minutes and requires no special tools. Instructions can be easily found online for your specific model.
Is this a new part?
No, this is a high-quality, tested computer that has been sourced from a salvaged vehicle. Each unit is inspected and professionally programmed to ensure it functions correctly and provides a long service life.
Will I need to do anything else after I install it?
Besides the security relearn procedure, no further programming is needed. It is a plug-and-play solution. We recommend disconnecting your battery before starting the installation for safety.
What if this doesn’t fix my problem?
While this 2003-2004 Alero 2.2L ECM is the solution for the symptoms listed, we always recommend proper diagnostics. If you have any questions before purchasing, please contact us. Our one-year replacement warranty covers the part itself in case of failure.
