Restore Your Vehicle’s Brain and Get Back on the Road
Is your Cadillac or Buick suffering from erratic engine behavior, stalling, poor fuel economy, or a persistent Check Engine light that just won’t go away? A failing Engine Control Module (ECM) can bring your daily drive to a frustrating halt. It’s the central computer of your vehicle, and when it falters, everything from engine timing to transmission shifting can be affected. This fully tested, genuine OEM Programmed 12592124 ECM is the direct-fit solution to restore your vehicle’s performance and get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty ECM can manifest in numerous ways, often mimicking other sensor failures and leading to costly, incorrect repairs. If you’re experiencing any of the following, this module is your definitive solution:
- No-Start or Hard-Start Conditions: The engine cranks but refuses to start, or takes an excessively long time to turn over.
- Rough Idle & Stalling: Your vehicle idles erratically or stalls unexpectedly at stops.
- Reduced Power & Poor Acceleration: A noticeable loss of power and sluggish response from the engine.
- Check Engine Light with Specific Codes: Often triggers Diagnostic Trouble Codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error), P0606 (ECM/PCM Processor Fault), or various communication (U-prefix) codes.
- Erratic Transmission Behavior: Harsh or delayed shifting as the ECM fails to communicate properly with the transmission control module.

Expert Insight: The Critical Role of VIN Programming
A common mistake DIYers and even some shops make is installing a used ECM without proper programming. These mid-2000s GM vehicles have a sophisticated anti-theft system (VATS/Passlock) that is inextricably linked to the vehicle’s VIN stored in the original computer. Simply swapping the module will result in a no-start condition, as the security systems won’t recognize each other. Our professional programming service handles this critical step for you, synchronizing the module to your car’s specific configuration before it even leaves our facility. This isn’t just a part; it’s a complete, ready-to-install solution that saves you time, money, and headaches.
By choosing our Programmed 12592124 ECM, you are not just buying a part; you are investing in a reliable fix that restores the heart of your vehicle’s electronics. We take the guesswork out of the repair, providing a module that is tested, verified, and pre-configured for your exact car. Simply provide your VIN upon checkout, and let us handle the technical complexities. Get your Cadillac or Buick running right again.
Frequently Asked Questions
Do I need to do any additional programming after I receive this ECM?
No. We pre-program the module to the VIN you provide, so it is ready to be installed. In some cases, a simple 10-30 minute security relearn procedure (turning the key on and off) may be required, which does not need any special tools. We include instructions for this easy process.
How do I provide you with my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is essential.
Is this a new part?
No, this is a high-quality, tested, and guaranteed used OEM part that has been sourced from a salvaged vehicle. This allows us to provide a reliable and affordable solution compared to a new dealership part.
My original ECM has a different part number. Will this still work?
Yes, this module is a direct replacement for several service numbers, including 12581144, 12588472, and 19260507. As long as your vehicle’s year, make, and model are on our compatibility list, this Programmed 12592124 ECM will function correctly.
Will this fix my car’s problem for sure?
This ECM is the solution for a wide range of electronic and drivability issues. However, it is crucial that your vehicle has been properly diagnosed. If you have confirmed through diagnostic testing that the ECM is the point of failure, then this part is the correct fix.
