Get Your Vehicle Running Right Again
Is your family’s Buick Terraza or GM vehicle suffering from frustrating and unpredictable issues? A persistent Check Engine Light, rough idling, poor fuel economy, or even a no-start condition can sideline your daily driver and cause immense stress. These are classic signs of a failing Engine Control Module (ECM), the critical computer that manages your engine’s performance. Instead of facing a costly trip to the dealership for diagnostics and programming, this is your direct, hassle-free solution. This genuine GM ECM arrives at your door fully programmed to your vehicle’s specific VIN, making the repair as simple as plug-and-play.
Common Symptoms & Your Solution
A failing ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a faulty module is a likely culprit:
- Persistent Check Engine Light (CEL) with codes like P0601, P0602, P0606, or other communication errors.
- Engine Stalling or Misfiring for no apparent reason.
- Noticeable Drop in Fuel Efficiency as the engine runs too rich or too lean.
- Difficulty Starting the Vehicle or a complete no-start situation.
- Transmission Shifting Problems or erratic behavior.

We take a genuine GM module and flash it with the latest, most stable factory software update matched specifically to your car using the VIN you provide.

An Expert’s Note on ECM Replacement
As a technician with over 20 years on the shop floor, I’ve seen the headaches ECM replacements can cause. In the past, you’d buy a used computer from a junkyard with an unknown history, tow your car to a dealer, and pay them a premium for programming—hoping it would all work. It was a gamble. This process changes everything. By programming the module before we ship it, we eliminate the biggest hurdle. You’re not just buying a part; you’re buying a complete, reliable solution that gets your family’s vehicle safely back on the road with minimal fuss.
Frequently Asked Questions
Do I need to have this ECM programmed?
No. The main benefit of our service is that we program the ECM for you before it ships. You just need to provide us with your vehicle’s 17-digit VIN during or after checkout. It will arrive ready for installation.
What is a VIN and where do I find it?
The VIN (Vehicle Identification Number) is your car’s unique 17-digit serial number. You can typically find it on a tag on the driver’s side of the dashboard (visible through the windshield), on your vehicle’s registration, or on your insurance card.
Is this a difficult part to install?
For most DIYers with basic tools, this is a straightforward installation. The ECM is typically located in the engine bay. The process involves disconnecting the battery, unplugging the electrical connectors from the old ECM, unbolting it, and then installing the new one in the reverse order. We always recommend consulting a repair manual for your specific vehicle’s procedure.
Will this fix my car’s problem for sure?
While this programmed 2006 Buick Terraza ECM 12607096 is the correct solution for a failed module, it’s essential that your vehicle has been properly diagnosed. This part will not fix issues caused by faulty sensors, wiring problems, or other mechanical failures. We recommend a thorough diagnosis by a qualified mechanic to confirm the ECM is the root cause.
Does this part require a ‘CASE relearn’ or other security procedures?
In many GM vehicles, a security relearn procedure (often called Passlock or Passkey) may be required after installation. This is a simple process you can typically do yourself in about 30 minutes with just the ignition key. A Crankshaft Variation Relearn (CASE relearn) may also be needed to turn off the check engine light, which requires a compatible scan tool. Please check your vehicle’s service manual for specific post-installation steps.
