Restore Peak Performance to Your GM 3.6L Engine
Is your Pontiac Torrent, Chevy Equinox, or Cadillac CTS running rough, stalling, or displaying a persistent Check Engine Light? The Engine Control Module (ECM), often called the vehicle’s brain, is the central command unit for your engine’s performance, fuel economy, and emissions. When it begins to fail, it can cause a cascade of confusing and frustrating problems. This genuine, used ECM, part number 12619582, is the definitive solution to restore your vehicle’s factory performance and reliability. Sourced from a salvaged vehicle, each unit is meticulously inspected and then programmed specifically to your vehicle’s VIN, ensuring a seamless, plug-and-play installation.
From the Diagnostic Bay
We had a 2009 Chevy Equinox with the 3.6L V6 come into the shop that was giving the owner fits. It had a random, intermittent misfire on cylinder 3 that would only happen under load. The owner had already replaced the spark plug, ignition coil, and even the fuel injector for that cylinder, but the problem persisted. Standard diagnostic tools weren’t showing a clear culprit. We hooked up our scope and monitored the injector pulse for cylinder 3. Sure enough, we saw the signal drop out unpredictably when the engine was revved. The wiring was solid, which led us straight to the source: a failing injector driver inside the ECM. A new module would have cost a fortune and required a trip to the dealer for programming. We sourced a quality used unit, programmed it to the vehicle’s VIN, and installed it. The misfire was gone instantly. It’s a classic example of how a failing ECM can mimic other component failures, costing you time and money on unnecessary parts.
Symptoms of a Failing Engine Control Module
A faulty ECM can manifest in various ways, often mimicking other sensor or component failures. If you’re experiencing any of the following, your engine computer could be the culprit:
- ✔ Check Engine Light: The most common sign, often with codes related to sensors, communication errors (U-codes), or processor faults (P06xx codes).
- ✔ Engine Stalling or Misfiring: The engine may stall for no reason, run rough, or misfire on one or more cylinders.
- ✔ Poor Fuel Economy: A failing ECM can’t properly manage the air-fuel mixture, leading to a noticeable drop in MPG.
- ✔ No-Start Condition: The engine may crank but refuse to start if the ECM is not firing the injectors or ignition coils.
- ✔ Transmission Shifting Issues: The ECM works with the Transmission Control Module (TCM), and a fault can cause harsh shifting or erratic gear changes.
- ✔ Intermittent Problems: Issues that come and go with temperature changes are a classic sign of internal circuit board failure in the ECM.

Frequently Asked Questions
How do I provide my VIN for programming?
After completing your purchase, please send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive this information, as the programming is essential for the part to function in your vehicle.
Is any additional programming required after installation?
In most cases, no. Our VIN programming handles the engine and transmission operating software. However, on some GM vehicles, a Security Relearn or Crankshaft Position Sensor (CASE) relearn may be necessary. These procedures can often be done without a scan tool and instructions can be easily found online or we can provide guidance.
Is this a new part?
No, this is a genuine, used OEM part that has been sourced from a salvaged vehicle. Each unit is inspected and tested to ensure it is fully functional before being programmed and shipped.
What if I order the wrong part?
We strongly encourage you to match your original part number and check the fitment list provided. Programming is specific to your VIN. If you are unsure, please contact us with your VIN before ordering, and we will be happy to verify compatibility for you.
Where is the ECM located on my vehicle?
For the Pontiac Torrent and Chevy Equinox, the ECM is typically located in the engine compartment on the driver’s side (LH). For the Cadillac CTS and SRX, it is usually found in the engine compartment on the passenger’s side (RH). Always disconnect the vehicle’s battery before attempting to remove or install the module.
