Restore Peak Performance to Your GM Vehicle
Is your vehicle suffering from frustrating issues like a persistent check engine light, poor fuel economy, stalling, or erratic shifting? These are common indicators of a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission function. When it falters, the entire vehicle’s performance and reliability are compromised. This genuine GM Engine Control Module, part number 12607096, is the definitive solution to get your car, truck, or SUV running smoothly again.
The Critical Advantage: VIN Programming Included
Don’t settle for a generic, unprogrammed module that will cause more headaches than it solves. We take the guesswork and expense out of the repair process. Before this module ships, our technicians will flash it with the latest official GM software updates, precisely matched to your vehicle’s unique Vehicle Identification Number (VIN). This crucial step ensures that the ECM communicates flawlessly with your vehicle’s other systems, including the anti-theft system (Passlock/Passkey), transmission, and instrument cluster. This means no expensive trips to the dealership for programming are required. It’s designed for a straightforward installation, getting you back on the road faster.
From the Diagnostic Bay
We once had a 2008 Chevy Trailblazer come in with a complaint of intermittent stalling and a check engine light for a random misfire. The owner had already replaced the spark plugs, ignition coils, and even a fuel injector based on advice from forums. The problem persisted. After hooking up our professional scan tool and monitoring the live data, we noticed the fuel trim and ignition timing commands from the ECM were erratic and inconsistent. The sensors were all reading correctly, but the ECM was making poor decisions. We installed a VIN-programmed ECM, performed the security relearn, and the truck ran perfectly. It’s a classic case of chasing symptoms when the root cause lies within the vehicle’s central computer.
Is Your Vehicle Showing Signs of ECM Failure?
A failing engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a faulty Programmed GM ECM could be the culprit:
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling or shutting off unexpectedly while driving.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Rough idling or engine misfires.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Harsh or unpredictable automatic transmission shifting.
- ✔ Loss of power and poor acceleration.
- ✔ Communication errors with diagnostic scan tools.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. The main benefit of our service is that this Programmed GM ECM arrives at your door already flashed with the correct GM software for your specific VIN. This saves you the time, cost, and hassle of a dealership visit.

We cannot ship the module until we receive your VIN. The programming is essential for the part to function correctly in your vehicle. We will contact you after your purchase to remind you, but providing it during checkout will ensure the fastest possible processing and shipping.
Is any additional setup required after I install it?
In many cases, you may need to perform a simple security relearn procedure, also known as a Passlock or Passkey relearn. This procedure can typically be done without any special tools and involves a sequence of key turns. Instructions are widely available online for specific models, or you can consult your vehicle’s service manual.
How can I be sure my old ECM is the problem?
While the symptoms listed are strong indicators, it is always best to have a proper diagnosis performed by a qualified technician. This involves checking for trouble codes, testing sensor inputs and outputs, and verifying power and ground connections to the ECM. This ensures you are replacing the correct part.
Will this part fit my vehicle?
