Is Your Saturn Relay Giving You Trouble?
Is your family’s Saturn Relay suddenly unreliable? Stalling at intersections, suffering from poor fuel economy, or displaying a stubborn check engine light can turn your go-to vehicle into a source of constant stress. These aren’t just annoyances; they’re signs that your vehicle’s brain, the Powertrain Control Module (PCM), may be failing. Don’t let a faulty computer keep you sidelined. We have the precise, cost-effective solution to get you back on the road with confidence.
Common Symptoms & Your Solution
A failing PCM can cause a wide range of confusing issues. If you’re experiencing any of the following, this pre-programmed module is your answer:
- Unexpected stalling or rough idling
- Complete no-start condition (engine cranks but won’t fire)
- Drastic decrease in fuel mileage
- Check Engine Light with Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0606
- Transmission shifting erratically or harshly
- Loss of communication with diagnostic scan tools
This genuine GM 2005-2006 Saturn Relay PCM is the definitive fix for these problems. Sourced from a salvaged vehicle and rigorously tested, it is professionally flashed with the latest official GM software updates, tailored specifically to your vehicle’s Vehicle Identification Number (VIN). This critical programming step ensures that it works seamlessly with your Relay’s specific systems right out of the box.

Expert Insight: We recently had a customer with a 2005 Chevy Uplander (a sibling to the Relay) that had a persistent ‘No Communication’ issue, leaving two different shops stumped. They feared a complex wiring problem. We recommended starting with the core component. After installing our VIN-programmed 2005-2006 Saturn Relay PCM, the van started instantly, and all diagnostic communication was restored. Sometimes, the most direct solution is the correct one—start with the brain.
Frequently Asked Questions
Do I need to do any programming myself?
Absolutely not. We handle all the programming before the part is shipped. It will arrive at your door ready to be installed, requiring no additional flashing or dealership visits.
How do I provide my VIN number?
After you complete your purchase, simply add your vehicle’s 17-digit VIN to the ‘notes’ section at checkout, or reply to your order confirmation email with the information. We cannot ship your part until we have your VIN.
Is this a new part?
No, this is a thoroughly tested, genuine OEM part that has been carefully removed from a salvaged vehicle. This allows us to provide a reliable, factory-correct part at a fraction of the cost of a new one.
Will this fix my check engine light?
If the check engine light is caused by a faulty internal processor or a software error within your original PCM (like a P0601 code), this unit is the correct fix. However, if the light is on for another reason (e.g., a bad oxygen sensor), that issue will need to be addressed separately.
What if my original part number is 12591856?
This PCM, part number 12591279, is the correct and updated replacement for part number 12591856. It is fully compatible and will work perfectly in its place.
What does ‘Plug & Play’ really mean?
It means the module arrives ready for installation without the need for special computerized tools or a trip to the dealer for programming. Once installed, you may need to perform a simple security relearn procedure, which can be done without any special tools and takes about 30 minutes. Instructions are readily available online.
