So your 2003 Tahoe is acting up and you're pretty sure it's the computer?
We got you.
This is a remanufactured ACDelco ECM (that's the Engine Control Module, also known as a PCM or ECU) with the part number 12582605.

We don't just send you a box of parts and hope for the best.

We program it specifically to your truck's VIN before it ships, so it's truly plug-and-play.

You get it, install it in the front engine bay, and hopefully, that check engine light is a thing of the past.

It's been fully tested and refurbed, so it's solid.

Made right here in the USA, and it comes with a manufacturer warranty for your peace of mind.

Just pop it in, follow the simple instructions included, and get your Tahoe running right again.
