Is Your Family Minivan Suddenly Unreliable?
There’s nothing more stressful than a vehicle you can’t trust, especially when it’s the one you rely on for school runs, errands, and family trips. If your 2006 Buick Terraza is experiencing frustrating issues like a persistent check engine light, rough idling, stalling, or a complete failure to start, the problem often points directly to a failing Powertrain Control Module (PCM). Don’t let a faulty computer sideline your daily life. This is the reliable, straightforward solution you need to restore your vehicle’s performance and your peace of mind.
Common Symptoms & Your Solution
A failing PCM can manifest in numerous ways, often triggering Diagnostic Trouble Codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (PCM Processor Fault).

An Expert’s Note: We recently helped a customer with a 2006 Chevy Uplander, which uses the same platform as your Terraza. He was experiencing random stalling in traffic—a dangerous and stressful situation for any parent. The dealership quoted him over a thousand dollars for a new PCM and programming. He ordered our 2006 Buick Terraza PCM 12600928, provided his VIN, and installed it in his driveway in under an hour. The stalling vanished, and he was back to safely driving his kids to soccer practice the same day, saving himself significant time, money, and anxiety.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, we will send you a message requesting your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your exact vehicle.
Do I need to do anything after installation?
In most cases, the module is ready to go. However, some vehicles may require a simple security relearn procedure (also known as a CASE relearn) which can typically be done without special tools. Instructions are widely available online or in service manuals.
Is this the correct part for my vehicle?
This module fits several 2006 and 2007 GM models, including the Terraza, Uplander, Montana, Rendezvous, Equinox, Torrent, G6, and Malibu with the 3.5L engine. Please verify that your original module has the service number 12600928 or 19210070 to ensure perfect compatibility.
What’s the difference between a PCM and an ECM?
The terms are often used interchangeably. PCM (Powertrain Control Module) typically controls both the engine and transmission, while an ECM (Engine Control Module) just controls the engine. For your 2006 Buick Terraza PCM 12600928, it functions as the central computer for the entire powertrain.
Will this fix my check engine light?
If the check engine light is caused by a faulty internal processor or software in your original PCM (like codes P0601-P0606), then this part is the correct solution. It’s always best to have the codes scanned to confirm the diagnosis before ordering.
