Frequently Asked Questions
Do I need to program this module after I receive it?
No. We program the module to the VIN you provide before we ship it to you. It will arrive ready for installation, with no additional dealer programming required.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a message or note to the seller during checkout or reply to your order confirmation email.
Will this fix my check engine light?
If the check engine light is on due to an internal failure of the original ECM (as diagnosed by a qualified mechanic), then this part will solve the problem. It is essential to ensure the ECM is the root cause of the issue before ordering.
Is this part difficult to install?
On the 2008-2009 Impala, the ECM is typically located in the lower part of the air cleaner box, making it relatively accessible.

We recommend consulting a service manual or professional technician if you are unsure.
