Is Your Vehicle Experiencing Mysterious Electrical or Performance Problems?
The Engine Control Module (ECM), often called the engine’s brain, is the central command center for your vehicle’s performance, fuel economy, and emissions. When it begins to fail, it can cause a cascade of confusing and frustrating issues, from a simple check engine light to a car that won’t start at all. If you’re dealing with poor engine performance, erratic behavior, or diagnostic codes that point to a faulty computer, you’ve found the definitive solution. This ECM, part number 12602044, is a direct-fit replacement, ready to restore your vehicle’s factory performance and reliability.
We had a 2008 Chevy Impala come into the shop that was a real head-scratcher. The owner complained of intermittent stalling at stoplights and occasional hard shifting, but there were no consistent trouble codes. Other shops had replaced the throttle body and transmission solenoids with no luck. After hooking up our professional scan tool and monitoring live data, we noticed the fuel trim and ignition timing values would occasionally drop out completely for a split second. This pointed to a processing error inside the ECM. We installed a VIN-programmed module just like this one, performed the security relearn, and the car ran perfectly. The customer was thrilled to finally have a reliable car again after months of chasing ghosts.
Diagnosing a Failing Engine Control Module
A failing ECM doesn’t always die suddenly. It often shows signs of intermittent failure that can be mistaken for other component issues. By replacing your faulty unit with our pre-programmed module, you are addressing the root cause of these problems and preventing further component damage. This is especially critical for maintaining the complex systems in modern GM vehicles.
Common Symptoms of a Bad 2006 Solstice Engine Module
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Engine stumbling, misfiring, or running rough.
- ✔ A noticeable decrease in fuel efficiency.
- ✔ Problems with the automatic transmission shifting, such as harsh or delayed shifts.
- ✔ The engine cranks but refuses to start.
- ✔ Complete loss of communication with diagnostic scan tools.
- ✔ Stalling for no apparent reason while driving or idling.
The Critical Advantage: VIN-Specific Programming
Don’t settle for a generic, off-the-shelf computer that requires an expensive trip to the dealership for programming. We take the hassle and expense out of the equation. Before this module ships, our technicians will flash it with the latest, most stable software release from General Motors, specifically matched to your vehicle’s unique Vehicle Identification Number (VIN). This ensures that all factory settings for the engine, transmission, and anti-theft system are correct from the moment you install it. This process makes our 2006 Solstice Engine Module a true plug-and-play solution for most vehicles, getting you back on the road faster.
This module is a direct replacement for a wide range of GM vehicles and is interchangeable with the following service numbers: 12590032, 12602044, 12603530, 12605843, 12607096, 12630457, and 19210737. Please verify fitment for your specific make and model using the compatibility list.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After completing your purchase, please send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without this information. You can typically find your VIN on your vehicle’s registration, insurance card, or on the driver’s side dashboard visible through the windshield.
Is any additional programming required after installation?
Our ECM comes fully programmed to your VIN. However, on many GM vehicles, you may need to perform a simple security relearn procedure (also known as a CASE relearn or Passlock relearn). This procedure can typically be done without any special tools and involves a series of key cycles. Instructions are widely available online for your specific model.
What if my original part number isn’t 12602044?
No problem. This ECM is a direct replacement for several service numbers, including 12590032, 12603530, 12605843, 12607096, 12630457, and 19210737. As long as your original part number is on this list, this module will function correctly in your vehicle once programmed to your VIN.
Do I need to send my old ECM back?
No core charge or return is required for this part. You can keep or responsibly dispose of your old module.
How long does the programming and shipping process take?
Programming is typically completed within one business day of receiving your VIN. After that, the module is shipped out via the method you select at checkout. We strive to get your vehicle back on the road as quickly as possible.
