Restore Peak Performance to Your Vehicle’s Engine
Is your Chevrolet Uplander or other GM vehicle suffering from perplexing engine issues? A flashing check engine light, rough idling, stalling, or a sudden drop in fuel economy are common signs that the brain of your engine—the Engine Control Module (ECM)—is failing. This replacement ECM, part number 12607096, is the definitive solution to restore your vehicle’s reliability, power, and efficiency. As the central command center, the ECM manages everything from fuel injection and ignition timing to emissions control and transmission shifting. When it falters, the entire vehicle’s performance suffers. Don’t let a faulty computer keep you off the road.
From the Diagnostic Bay
We had a 2008 Chevy Impala come into the shop with a persistent P0300 random misfire code. The owner had already replaced all the spark plugs, wires, and even the coil packs, but the check engine light and rough running condition wouldn’t go away. After hours of chasing our tails checking fuel pressure and vacuum leaks, we finally hooked up a scope to the injector drivers at the ECM. We found that the signal for cylinder 3 was erratic. A quick swap with one of our tested and programmed modules, like this one, solved the problem instantly. The customer had spent hundreds on parts they didn’t need when the core issue was the computer itself. It’s a classic reminder to always consider the ECM when multiple, unrelated codes or strange electrical issues appear.
Is Your Engine Control Module Failing?
A failing ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your engine computer could be the culprit:
- ✔ Check Engine Light is illuminated, often with communication-related or random misfire codes.
- ✔ Your vehicle fails to start or starts intermittently.
- ✔ Noticeable decrease in fuel efficiency for no apparent reason.
- ✔ The engine stalls, stutters, or hesitates during acceleration.
- ✔ Rough or erratic idling.
- ✔ Automatic transmission shifts harshly or at the wrong times.
- ✔ Loss of power and poor overall engine performance.
The Plug-and-Play Solution: A Programmed 2006 Uplander ECM
Replacing an ECM isn’t just about swapping hardware. Modern vehicles require the module to be programmed specifically to the car’s Vehicle Identification Number (VIN) and its unique options. Our service eliminates the need for an expensive trip to the dealership. When you order, simply provide us with your vehicle’s VIN. Our technicians will flash this module with the latest, most stable GM factory software for your exact vehicle. This ensures that all systems communicate correctly, anti-theft systems are properly configured, and your engine operates exactly as the manufacturer intended. This is a direct-fit replacement, making installation straightforward for a DIY mechanic or your trusted shop.
This module is a direct replacement for a wide range of service numbers, including 12590032, 12602044, 12603530, 12605843, 12607096, 12630457, and 19210737, ensuring broad compatibility across dozens of GM models from Buick, Chevrolet, Cadillac, Pontiac, Saturn, GMC, and more. Please verify the fitment list to confirm it matches your specific vehicle.
Frequently Asked Questions
How does the VIN programming service work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the correct GM factory software for your specific make, model, year, and options. We then flash this software onto the module before shipping it to you. This makes the unit ready for installation upon arrival.
Will I need to do any additional programming after installation?
In most cases, no additional programming is needed. However, many GM vehicles of this era require a simple “security relearn” or “CASE relearn” procedure after the ECM is installed. This can typically be done without special tools and involves a sequence of key turns. Instructions for this procedure are widely available online or in service manuals.
Is this a new or used part?
This is a high-quality, genuine OEM component that has been thoroughly tested to ensure it meets or exceeds original factory specifications. We guarantee its functionality and performance when programmed for your vehicle.
How can I be sure the ECM is the actual problem?
While the symptoms listed are strong indicators, it is always best to have a proper diagnosis performed by a qualified technician. Common issues like bad grounds, wiring problems, or faulty sensors can sometimes mimic ECM failure. A full diagnostic scan checking for communication codes (U-codes) and confirming power and ground at the ECM connector is the best way to be certain.
What happens if I provide the wrong VIN?
Providing the correct VIN is critical. An incorrect VIN will result in the wrong software being loaded, which will cause starting issues, system malfunctions, and warning lights. Please double-check your VIN from your driver’s side dashboard plate or door jamb sticker before sending it to us.
