Restore Your Minivan’s Reliability and Performance
Is your 2008 or 2009 Pontiac Montana suffering from frustrating and unpredictable engine problems? A persistent check engine light, rough idling, stalling, or poor fuel economy can disrupt your family’s daily routine and create unnecessary stress. These issues often point directly to a failing Engine Control Module (ECM), the central computer of your vehicle. This replacement module is the definitive, hassle-free solution to get your trusted family vehicle running smoothly and safely again.
Common Symptoms & Your Solution
A failing ECM can cause a wide range of issues that are often misdiagnosed. If you’re experiencing any of the following, a faulty computer is the likely culprit:
- Persistent Check Engine Light (CEL)
- Diagnostic Trouble Codes (DTCs) like P0601, P0606, or other communication errors
- Unexplained engine stalling or hesitation
- Noticeable decrease in fuel mileage
- Rough or erratic engine idle
- Transmission shifting problems or harsh shifts
- Failure to pass emissions testing
This unit is your direct solution. We take a genuine GM module and program it specifically to your vehicle’s unique Vehicle Identification Number (VIN) before it ever leaves our facility. This critical step ensures that all systems communicate perfectly, resolving the root cause of your problems and restoring your vehicle to its factory specifications.

A Technician’s Insight: As a tech with over 20 years on the job, I’ve seen countless families frustrated by ECM issues. The most common mistake is installing a used, un-programmed unit from a junkyard. It simply won’t work because the vehicle’s anti-theft system (VATS/Passlock) won’t recognize it. Our process of programming the Pontiac Montana ECM 12607096 to your specific VIN *before* shipping eliminates this headache. It’s the closest you can get to a true plug-and-drive repair, saving you time, money, and the stress of a tow to the dealer.
Frequently Asked Questions
Do I need to do any programming after I install it?
No programming is required. We handle the main programming to your VIN before shipping. However, on most GM vehicles, you will need to perform a simple security relearn procedure after installation. This can typically be done in your driveway with just the key and takes about 30 minutes. We include instructions to guide you through this easy process.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the module to work in your vehicle.
Is this compatible with other vehicles besides the Pontiac Montana?
Yes. This ECM, service number 12607096, is compatible with a very wide range of GM vehicles. The provided fitment list shows many of the compatible models. The key is to match the service number from your original part to one of the numbers listed to ensure compatibility.
What if the part number on my old ECM is different?
That’s very common. GM uses many interchangeable service numbers for the same computer. As long as the number on your original module is included in our cross-reference list (e.g., 12590032, 12602044, 12630457, etc.), this part will be a correct replacement for your vehicle.
What tools are needed for installation?
Installation is typically straightforward. You will usually only need basic hand tools, such as a socket set and a screwdriver. The most important first step is to disconnect the vehicle’s battery before you begin.
