Restore Peak Performance to Your GM Vehicle
Is your 2008-2009 Cadillac SRX, CTS, or Pontiac G8 suffering from perplexing issues like a persistent check engine light, rough idling, stalling, or a complete no-start condition? These are often hallmark signs of a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle’s powertrain, meticulously managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it falters, the entire system’s performance and reliability are compromised. This listing offers a direct, reliable solution: a genuine, used OEM Engine Control Module, part number 12619582 (interchangeable with 12623327 and 12614423), fully programmed to your vehicle’s specific Vehicle Identification Number (VIN).
From the Diagnostic Bay
We recently had a 2008 Cadillac CTS with the 3.6L engine come into the shop. The owner had already replaced the spark plugs, ignition coils, and even a fuel injector trying to chase down an intermittent misfire and poor fuel economy. The codes were all over the place, pointing to different cylinders on different days. After hours of diagnostics, we hooked up our scope to the injector driver circuits directly at the ECM connector. We discovered the control signal from the ECM was erratic and weak, causing the misfire. A new, programmed ECM fixed the issue instantly. This story highlights how a faulty ECM can send you down a rabbit hole of replacing perfectly good parts. Always consider the vehicle’s computer when symptoms are inconsistent and widespread.
Is a Failing 2008-2009 SRX ECM Causing Your Problems?
A malfunctioning engine computer can manifest in numerous ways, often mimicking other component failures. By replacing your faulty module with our pre-programmed unit, you can resolve these complex issues and get your vehicle running smoothly again. This part is the key to restoring the precise calculations needed for optimal engine function.
Common Symptoms of a Faulty ECM
- ✔ Persistent and illuminated Check Engine Light (CEL)
- ✔ Engine stalling or shutting off unexpectedly while driving
- ✔ Rough or erratic engine idle
- ✔ Noticeable decrease in fuel efficiency
- ✔ Difficulty starting the engine or a no-start condition
- ✔ Hesitation or stumbling during acceleration
- ✔ Communication errors with diagnostic scan tools
- ✔ Seemingly random warning lights on the instrument cluster
A Simple, Plug-and-Play Solution
We take the guesswork and high dealership costs out of replacing your engine computer. This is not a generic, one-size-fits-all module. When you purchase from us, you provide your vehicle’s VIN. Our technicians then use that information to flash the module with the latest, most stable GM-approved software for your exact vehicle configuration. This ensures that the ECM communicates perfectly with your engine, transmission, anti-lock brake system, and all other onboard modules right out of the box. While the module is plug-and-play, some GM vehicles may require a simple security relearn procedure (often called a Passlock or Passkey relearn), which can typically be done without special tools and takes about 30 minutes. Instructions are readily available online for this common procedure.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before the part is shipped. You simply need to provide us with your vehicle’s 17-digit VIN during or after checkout. The module will arrive ready for installation.
Is this a new part?
No, this is a genuine used OEM part that has been sourced from a salvaged vehicle. Each unit is carefully inspected and tested to ensure it is fully functional before being programmed and shipped.
Will I need to have my keys reprogrammed?
In most cases, you will not need to reprogram your keys. However, you may need to perform a security relearn procedure, which syncs the new ECM to your vehicle’s anti-theft system. This procedure typically takes 30-40 minutes and does not require a scan tool.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific car. It contains information about the make, model, year, and factory-installed options. We use the VIN to load the exact software and calibrations your vehicle requires for proper operation.
What if the part doesn’t fix my problem?
While a faulty ECM is a common cause for many engine issues, proper vehicle diagnosis is crucial. We guarantee that you will receive a functional, correctly programmed module. If the part does not resolve your issue, it’s possible the problem lies with another component. We recommend consulting with a qualified technician for a complete diagnosis.
