Is your 2006 Chevrolet Uplander suffering from frustrating and unpredictable engine problems? A faulty Engine Control Module (ECM) is often the culprit behind issues like stalling, rough idling, a persistent check engine light, or even a no-start condition. Restore your vehicle’s reliability and performance with this direct-fit replacement ECM, part number 12590032. This isn’t just a part; it’s a complete solution. We program the module specifically to your vehicle’s VIN with the latest GM software updates before it ships, ensuring a straightforward installation process and optimal engine performance.
Understanding the Role of Your 2006 Uplander ECM
The Engine Control Module is the central computer, or ‘brain,’ of your vehicle’s engine management system. It constantly analyzes data from sensors throughout the engine to control critical functions like fuel injection timing, spark advance, transmission shifting, and emissions systems. When the ECM begins to fail, it can send incorrect commands, leading to a cascade of performance issues that can be difficult to diagnose. Replacing a faulty module with a properly programmed unit is essential to getting your Uplander running smoothly and efficiently again.
From the Diagnostic Bay
We once had a 2006 Uplander in the shop that had been to three other mechanics for a random stalling issue. The owner had replaced the fuel pump, spark plugs, and even the crankshaft sensor, but the problem persisted. After hooking up our professional scan tool, we noticed erratic data coming from the ECM itself. The internal processors were failing intermittently under heat. We installed a VIN-programmed ECM just like this one, and the van ran perfectly. It’s a powerful reminder that sometimes the issue lies with the computer that controls everything else.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light is illuminated, often with communication-related trouble codes (U-codes).
- ✔ Engine stalls unexpectedly or struggles to start.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough or erratic engine idling and hesitation during acceleration.
- ✔ Transmission shifting problems or harsh engagement.
- ✔ Misfires or poor engine performance with no other apparent cause.
- ✔ Complete failure to start the engine, with no spark or fuel delivery.

Frequently Asked Questions
Do I need to have this ECM programmed?
No. We handle all the programming for you before we ship the part. All you need to do is provide your vehicle’s VIN during or after checkout.
What happens if I forget to provide my VIN?
We cannot ship your order without the VIN. The module will not function in your vehicle without being programmed correctly. We will contact you to retrieve the VIN before processing your order.
Is this part difficult to install?
The physical installation is typically straightforward. On the 2006 Uplander, the ECM is located in the left-hand (driver’s side) engine compartment. After installation, you may need to perform a security relearn procedure, which usually involves a sequence of key turns. Instructions are readily available online or in service manuals.
Will this fix my check engine light?
If the check engine light is on due to a fault within the original ECM, this replacement part will solve the problem. However, if the light is caused by another failing sensor or component, you will still need to address that separate issue.
Is this a new or used part?
This is a high-quality, tested, and guaranteed functional used OEM part. It has been inspected and is ready for programming and installation in your vehicle.
