Restore Peak Performance to Your C6 Corvette
Is your 2008 or 2009 Corvette suffering from mysterious electrical issues, a persistent check engine light, or poor engine performance? The Engine Control Module (ECM), often called the Powertrain Control Module (PCM), is the central computer of your vehicle. It manages everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, it can cause a wide range of frustrating and difficult-to-diagnose problems. This replacement ECM, part number 12622141, is the definitive solution to get your Corvette back on the road and running like the high-performance machine it was designed to be.
This isn’t just a part in a box. We provide a crucial service that makes this a true plug-and-play solution. Upon purchase, you will provide us with your vehicle’s VIN. Our technicians will then program the module with the latest, most stable software directly from GM, ensuring it is perfectly matched to your Corvette’s specific configuration. This vital step eliminates the need for an expensive trip to the dealership for programming, saving you both time and money.
From the Diagnostic Bay
We had a 2008 Corvette Z06 come in with a complaint of intermittent stalling and a random misfire code that mechanics couldn’t pin down. They had replaced plugs, wires, and even a coil pack. After hours of diagnostics, we traced the issue to a failing driver circuit inside the original ECM. It would heat up and intermittently fail, causing the misfire. Installing a correctly programmed replacement ECM like this one solved the problem instantly. The owner was thrilled to have his car’s legendary performance restored after chasing ghosts for weeks.
Symptoms of a Failing 2008-2009 Corvette Engine Control Module
A failing ECM can manifest in numerous ways. If you’re experiencing any of the following, a faulty module could be the culprit:
- ✔ Check Engine Light (CEL) is illuminated with various trouble codes.
- ✔ Engine cranks but refuses to start.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough idling, stalling, or hesitation during acceleration.
- ✔ Misfire codes (e.g., P0300-P0308) that don’t resolve with new plugs or coils.
- ✔ Transmission shifting issues or harsh engagement.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Intermittent electrical problems that seem to have no other cause.
The Importance of VIN Programming
Modern vehicles like the C6 Corvette have complex systems that are interconnected. The ECM must communicate with the Body Control Module (BCM), Transmission Control Module (TCM), and anti-theft system (Pass-Key/VATS). Simply installing a used, unprogrammed module will result in a no-start condition. Our VIN programming service ensures that this module is a direct replacement, recognized by all other systems in your vehicle. It arrives ready for installation, with only a simple security relearn procedure potentially required, which can often be done without special tools.
This module is a direct replacement for part numbers 12622141, 12612384, and 12617568 and fits a wide variety of GM vehicles beyond the Corvette, including select models of the Sierra, Silverado, Tahoe, Suburban, Escalade, and more. Please verify the part number and consult the fitment list to ensure compatibility with your specific vehicle.
Frequently Asked Questions
Do I need to have this module programmed?
No. This module comes pre-programmed to your vehicle’s specific VIN. After you place your order, you will need to provide us with your VIN so we can flash the unit with the latest GM software before shipping.
What is a security relearn or CASE relearn?
A security relearn syncs the new ECM with your vehicle’s anti-theft system. A CASE (Crankshaft Angle Sensor Error) relearn syncs the ECM with the crankshaft position sensor. Depending on your vehicle, one or both of these quick procedures may be required after installation. Many can be performed at home, while some may require a scan tool.
Is this a plug-and-play part?
Yes, because we handle the programming, it is designed to be a direct-fit, plug-and-play installation. Once installed, you may only need to perform the security/CASE relearn procedures mentioned above.
How do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
Will this fix my car’s specific problem?
This module will correct issues directly caused by a faulty ECM. While the symptoms listed are common indicators of ECM failure, we always recommend a proper diagnosis by a qualified technician to confirm the ECM is the root cause before ordering.
