Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions to send us your vehicle’s 17-digit VIN. We cannot program or ship your module until we receive this information.
Is this part difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the module. However, some GM vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn) after installation, which can be done with specific key-on/key-off cycles or a capable scan tool. We recommend consulting a service manual for your specific model.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of your original ECM (as indicated by codes like P0601 or P0606), this part is the correct solution. It’s always best to have a professional diagnosis to confirm the ECM is the root cause before ordering.
What does the ECM actually do?
The Engine Control Module is your vehicle’s central computer. It processes information from sensors all over the engine to control fuel injection, spark timing, emissions systems, and more. A functioning ECM is essential for your engine to run smoothly and efficiently.
