Restore Peak Performance to Your Vehicle’s Engine
Is your Chevrolet Uplander, or another compatible GM vehicle, suffering from erratic behavior, poor fuel mileage, or a persistent Check Engine Light? The Engine Control Module (ECM), often called the engine’s brain, is the central command unit responsible for managing everything from fuel mixture and ignition timing to transmission shifts and emissions. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems. This replacement Engine Control Module, service number 12630457, is the definitive solution to restore your vehicle’s reliability and drivability.
Unlike a standard part from a salvage yard, this module is not just a component; it’s a complete, ready-to-install solution. We take the guesswork and extra expense out of the repair by programming the module specifically for your vehicle using your VIN. This critical step ensures that the ECM communicates flawlessly with all other onboard systems, just as it did from the factory. It arrives loaded with the latest GM software updates, often correcting underlying issues you didn’t even know were present.
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 ECM could be the culprit:
- ✔ Check Engine Light: The light is on, and you may have codes related to sensor circuits, module communication, or random misfires.
- ✔ Engine Performance Issues: Noticeable loss of power, hesitation during acceleration, rough idling, or stalling.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG is a common symptom as the ECM can no longer efficiently manage the fuel delivery.
- ✔ Transmission Problems: The ECM works with the transmission controller, and a failure can lead to harsh shifting, getting stuck in gear, or incorrect shift points.
- ✔ No-Start Condition: The engine may crank but will not start because the ECM is not firing the ignition coils or fuel injectors.
- ✔ Intermittent Stalling: The vehicle may run fine for a while and then suddenly shut off, often without warning.

What information do you need from me?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). This allows us to load the correct factory software and calibrations for your exact vehicle.
Where is the ECM located on a 2006 Chevy Uplander?
On the 2006 Uplander, the Engine Control Module is typically located in the left-hand (driver’s side) engine compartment. Always disconnect the battery before attempting to remove or install any electronic modules.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s essential to properly diagnose the vehicle first, as the light can be triggered by many other failing components. This module will fix issues stemming from an internal computer failure.
Is this part compatible with other vehicles besides the Uplander?
