Is your 2006 Buick Terraza suffering from perplexing issues like stalling, poor fuel economy, a persistent check engine light, or even a no-start condition? These are common signs of a failing Engine Control Module (ECM), the central computer responsible for managing your vehicle’s engine performance. Don’t let a faulty computer keep your van off the road. This direct-fit Engine Control Module, service number 12590032, is the reliable and straightforward solution to restore your vehicle’s peak performance and drivability.
The ECM is the brain of your engine, constantly analyzing data from sensors to control fuel injection, ignition timing, and emissions systems. When it fails, it can cause a cascade of problems that are often difficult to diagnose. Replacing it with a generic, non-programmed unit from a parts store often leads to more headaches, requiring expensive trips to the dealership for programming. We eliminate that step entirely. Upon purchase, simply provide us with your vehicle’s VIN, and our technicians will program this module with the latest, most stable software updates from General Motors. This ensures perfect compatibility and optimal function right out of the box.
From the Diagnostic Bay
We had a 2006 Terraza come into the shop with a complaint of intermittent stalling at stoplights and a check engine light that would come and go. The owner had already replaced the spark plugs and an oxygen sensor with no luck. Our scan tool showed communication errors with the ECM. Instead of spending hours chasing phantom electrical gremlins, we identified the ECM as the root cause. A quick swap with one of our VIN-programmed modules had the van running perfectly in under an hour. The customer was thrilled to have their reliable family vehicle back without the massive bill and wait time from a dealership.

Your Vehicle Identification Number (VIN) allows us to load the exact GM-specified software for your vehicle’s engine, transmission, and options. This ensures the module works perfectly upon installation without needing a trip to the dealer.
Is this a plug-and-play part?
Yes, this module is shipped ready to be installed. In most cases, you will simply need to perform a straightforward security relearn procedure, which can be done without special tools and typically takes 10-30 minutes. We include instructions for this process.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty ECM, this replacement will resolve the issue. It’s crucial to ensure that the problem has been correctly diagnosed and is not related to other sensors or components.
Where is the ECM located on a 2006 Buick Terraza?
On the 2006 Terraza, the Engine Control Module is typically located in the LH (driver’s side) engine compartment. Always disconnect the battery before attempting removal or installation.
What if I have a different GM vehicle from the fitment list?
The process is the same. This ECM is compatible with all the vehicles listed. Just provide the VIN for the specific vehicle you are installing it in, and we will program it accordingly.
