Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before we ship the part. It will arrive ready to be installed in your vehicle. All you need to provide is your VIN.
What is a VIN and where do I find it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your vehicle. You can typically find it on a sticker inside the driver’s side door jamb, on your vehicle’s registration, or on your insurance card.
Will this fix my check engine light?
If the check engine light is on due to a fault with the original PCM, this part will resolve the issue. However, if there are other mechanical or electrical problems with the vehicle, the light may remain on until those are addressed as well.
Is a security relearn procedure required after installation?
For most 2004 GM trucks and SUVs, a simple security relearn procedure is necessary to sync the new PCM with your keys. This typically takes about 10-15 minutes and involves turning the key in the ignition. We include straightforward instructions to guide you through this easy process.
How do I confirm this is the right part for my vehicle?
The best way is to match the service number from your original computer to one of the numbers listed in our description (e.g., 12586242, YFKD, etc.). You can also use the comprehensive fitment list provided on this page to confirm your make, model, and engine.
What if I order the wrong part?
We strongly encourage you to verify your part number before ordering. Because these units are programmed to a specific VIN, it’s crucial to get it right the first time. If you have any doubts, please contact us with your VIN, and we will be happy to verify compatibility for you.
