Restore Your Terraza’s Performance and Reliability
Is your 2006 Buick Terraza running rough, stalling unexpectedly, or showing a persistent check engine light? A failing Engine Control Module (ECM) can be the source of immense frustration, making your family’s vehicle unreliable and unpredictable. Put an end to the guesswork and restore your minivan’s dependability with our professionally programmed ECM. This is the definitive, plug-and-play solution designed to get you back on the road with confidence and peace of mind.
Common Symptoms & Your Solution
A faulty ECM can manifest in numerous ways, often mimicking other sensor or component failures. If you’re experiencing any of the following, your engine’s computer may be the culprit:
- Persistent Check Engine Light (CEL) with codes like P0601, P0602, or P0606

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used ECM from a salvage yard. This almost never works. Modern GM vehicles use a sophisticated anti-theft system (VATS/Passlock) that links the ECM to other modules like the Body Control Module (BCM) and ignition key. Without proper VIN programming, these components can’t communicate, and your vehicle simply will not start. Our service eliminates this critical roadblock, delivering a component that is electronically matched to your Terraza, saving you time, money, and the headache of a no-start situation.
By choosing our pre-flashed 2006 Buick Terraza ECM 12590032, you are not just buying a part; you are investing in a reliable repair that restores your vehicle’s original functionality and your confidence as a driver. Don’t let a faulty computer keep your family van sidelined.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. We handle all the programming for you before shipment. All we need is your vehicle’s 17-digit VIN. The module will arrive ready for you to install.
What information do you need from me after I order?
After you complete your purchase, please send us your vehicle’s VIN. This allows us to program the 2006 Buick Terraza ECM 12590032 with the correct software and calibration for your specific vehicle.
Is this a difficult part to install?
For most individuals with basic mechanical skills, this is a straightforward installation. It typically involves disconnecting the vehicle’s battery, unplugging the electrical connectors from the old ECM, removing a few mounting bolts, and then installing the new one in the reverse order. In some cases, a security relearn procedure may be required, which can be done without special tools and instructions can easily be found online.
How can I be sure my ECM is the actual problem?
While the symptoms listed above are strong indicators of a failing ECM, we always recommend a proper diagnosis by a qualified mechanic. This ensures you are replacing the correct part and avoids unnecessary expenses. Common diagnostic trouble codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error) are a definitive sign of ECM failure.
Will this fix my check engine light?
If the check engine light was caused by an internal failure of the ECM, then yes, this part will resolve the issue and allow the light to be cleared. However, if the light is on due to other failing sensors or components on the vehicle, those issues will still need to be addressed separately.
What other vehicles does this ECM fit?
This ECM, identified by service number 12590032 and its interchanges, fits a very wide range of General Motors vehicles from the mid-2000s, including models from Chevrolet, Buick, GMC, Pontiac, Cadillac, Saturn, and more. Please verify the part number or use the fitment chart to confirm compatibility with your specific vehicle.
