Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM) is your vehicle’s main computer, often called its “brain.” It controls critical functions like fuel injection, spark timing, idle speed, and emissions systems to ensure the engine runs efficiently and reliably.
Is this part ready to install when it arrives?
Yes, this ECM is pre-programmed to the VIN you provide, making it ready for installation. In some cases, your vehicle may require a simple “security relearn” procedure after installation, which pairs the new module to your keys. This procedure can typically be done without special tools and instructions are widely available online.
How do I give you my vehicle’s VIN?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is essential for the part to work correctly.
Will this fix my car’s problem for sure?
This module will resolve any issues directly caused by a faulty ECM. However, it’s crucial that your vehicle has been properly diagnosed. Symptoms like misfires or stalling can also be caused by other failing parts, such as sensors or fuel system components. We recommend confirming the diagnosis before ordering your 2003-2005 Grand Am ECM 12576162.
Is this a new part?
No, this is a high-quality, used ECM that has been carefully removed from a salvaged vehicle. Each unit is inspected and tested to ensure it is fully functional before being programmed and shipped to you.
