Restore Peak Performance to Your Vehicle
Is your vehicle suffering from frustrating issues like a persistent check engine light, poor fuel economy, unexpected stalling, or a complete no-start condition? These are common signs of a failing Engine Control Module (ECM), the central computer responsible for managing your engine’s performance. This direct-fit replacement ECM, part number 12630457, is the definitive solution to restore your vehicle’s reliability and drivability. We take the guesswork and hassle out of the repair by programming the module specifically to your vehicle’s VIN before it ships, ensuring a seamless integration process.
From the Diagnostic Bay
We recently had a 2008 GMC Envoy come into the shop with an intermittent stalling problem that had stumped two other mechanics. The owner had already replaced the fuel pump and crankshaft position sensor to no avail. The vehicle would run fine for days, then suddenly die at a stoplight. After extensive testing, we hooked up an oscilloscope and monitored the 5-volt reference signal from the ECM. We discovered the voltage would momentarily drop, causing the sensors to lose power and the engine to shut down. A failing internal component in the original ECM was the culprit. Installing a new, properly programmed module like this one solved the problem for good, saving the customer from further expensive and incorrect repairs.
Symptoms of a Failing Engine Control Module
- ✔ Persistent Check Engine Light (CEL)
- ✔ Engine stalling or misfiring unexpectedly
- ✔ Difficulty starting the engine or a no-start condition
- ✔ Noticeable decrease in fuel efficiency
- ✔ Poor engine performance, hesitation, or rough idling
- ✔ Automatic transmission shifting problems
- ✔ Communication errors with diagnostic scan tools
The Critical Solution: A Pre-Programmed 2006 Solstice Engine Module
The Engine Control Module is more than just a part; it’s the brain of your vehicle’s powertrain. It processes information from dozens of sensors to control fuel injection, ignition timing, emissions systems, and transmission shifting. When it fails, the entire system is compromised. Our service eliminates the most difficult part of the replacement process: programming. Dealerships often charge hundreds for this service alone. We use the latest GM-certified software to flash this module with your vehicle’s unique VIN and all factory software updates. This ensures that all vehicle-specific options and security systems communicate correctly from the moment of installation.
This module is a direct replacement for a wide range of GM vehicles and is interchangeable with service numbers 12590032, 12602044, 12603530, 12605843, 12607096, 12630457, and 19210737. Simply provide your VIN after purchase, and we’ll handle the rest, delivering a part that is ready for installation.
Frequently Asked Questions
Is this part difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. Since we program the unit to your VIN, the complex software side is already handled. However, some vehicles may require a simple security relearn procedure or a Crankshaft Variation (CASE) relearn, which can often be done without specialized tools. We recommend consulting a service manual for your specific vehicle’s procedure.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have this information, as the programming is essential for the part to function in your vehicle.
Why is programming to my VIN so important?
Programming the ECM to your VIN ensures it works correctly with your vehicle’s specific options, engine calibration, transmission type, and, most importantly, the anti-theft system (PassLock/VATS). An unprogrammed module will not allow the vehicle to start.
My original part number is different. Will this still work?
Yes, as long as your original part number is one of the listed interchangeable service numbers (e.g., 12590032, 12602044, etc.). Manufacturers often update part numbers over time. This module is a verified replacement for all the numbers listed in the description.
Do I need to send my old module back?
No, there is no core charge for this part. You can keep or recycle your old module without needing to return it to us.
