Frequently Asked Questions
What exactly does an Engine Control Module do?
The ECM, or Engine Control Module, is the main computer that controls your vehicle’s engine. It takes data from sensors all over the engine to manage fuel injection, ignition timing, emissions systems, and transmission shifting to ensure optimal performance and efficiency.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we have this information to program the module correctly.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is straightforward. It typically involves disconnecting the car battery, unplugging the electrical connectors from the old ECM, unbolting it, and then installing the new one in its place. The most critical part is ensuring the battery is disconnected to prevent electrical damage.
Will I need to do anything after I install it?
In many GM vehicles, you will need to perform a security relearn procedure (also known as a VATS relearn) after installation. This process syncs the new ECM with your vehicle’s anti-theft system and keys. It’s a simple procedure that typically takes 30 minutes and does not require special tools.
Will this fix my check engine light?
If the check engine light is on due to a fault within the original ECM, this part is designed to be the solution. After installation, it’s always a good practice to clear any old codes with a standard OBD-II scanner to confirm the fix.
How can I be sure this fits my vehicle?
This module fits a very wide range of GM vehicles. Please review the detailed fitment list provided on this page. The most important step is to provide us with your VIN, which we use to confirm compatibility and program the 2006 Cobalt Engine Control Module specifically for your vehicle’s factory configuration.
