Restore Peak Performance to Your C6 Corvette
There’s nothing more frustrating than when your high-performance machine, like a 2006-2007 Corvette, starts acting up. Unexplained stalling, a persistent check engine light, poor fuel economy, or a dreaded no-start condition can sideline your vehicle and your driving enjoyment. As a technician with over two decades of experience under the hood, I’ve seen these exact issues countless times. The culprit is often a failing Engine Control Module (ECM)—the computer that serves as the brain of your engine’s operations.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take a genuine GM Engine Control Module (interchangeable with part numbers 12589297, 12597121, 12603892, and 19210738) and professionally program it with the latest GM software updates specifically for your vehicle. All we need is your Vehicle Identification Number (VIN) at checkout. This critical step ensures that when the module arrives, it communicates flawlessly with your Corvette’s specific systems, from the transmission to the anti-lock brakes, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay: The Ghost in the Corvette
I recall a 2007 Corvette that came into the shop with a truly maddening problem. The owner complained of random no-start conditions. Sometimes it would fire right up, other times it would just crank endlessly. We’d get intermittent communication loss codes (U0100) and a history code for internal processor failure (P0601). We spent hours checking wiring, grounds, and power feeds, but everything tested fine. The issue was a hairline fracture on the ECM’s internal circuit board. It would expand and contract with temperature, causing the intermittent failure. We installed one of our pre-programmed ECMs, and the ‘ghost’ was gone. The car started reliably every single time, restoring both its function and the owner’s peace of mind.
Signs Your Corvette’s Brain is Failing
A faulty ECM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your engine computer needs attention. Replacing your failing 2006-2007 Corvette ECM is the most reliable way to solve these problems for good.
- ✔ Check Engine Light is on with codes like P0601, P0606, or U-series communication codes.
- ✔ The engine cranks but refuses to start.
- ✔ Stalling or hesitation, especially after the engine has warmed up.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Poor or erratic automatic transmission shifting.
- ✔ Misfires or rough idling that can’t be traced to plugs, coils, or injectors.
- ✔ Loss of communication with other vehicle modules.
Your C6 Corvette ECM Installation Roadmap
Installing your new ECM is a straightforward process that a confident DIYer can handle. This module is located in the right-hand (passenger side) engine compartment on the Corvette. Always consult a service manual for your specific vehicle, but here are the general steps:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On the 2006-2007 Corvette, find the ECM mounted in the engine bay on the passenger side, near the front of the vehicle.
- Disconnect Wiring: Carefully release the locking tabs on the electrical connectors and gently pull them straight out from the module. Do not force them.
- Remove the Old ECM: Unbolt the old module from its mounting bracket. Keep the hardware as you will reuse it.
- Install the New ECM: Mount your new, pre-programmed ECM onto the bracket and secure it with the original hardware.
- Reconnect Wiring: Plug the harness connectors firmly into the new module. You should hear or feel a ‘click’ as they lock into place.
- Power Up: Reconnect the negative battery terminal.
- Security Relearn: You may need to perform a simple security relearn procedure. This typically involves turning the key to the ‘ON’ position for 10-15 minutes. Your vehicle’s security light should turn off, indicating the system has recognized the new ECM.

Frequently Asked Questions
Frequently Asked Questions
What exactly does this Engine Control Module do?
The ECM is your vehicle’s main computer. It controls critical engine functions like fuel mixture, ignition timing, and emissions systems to ensure optimal performance, fuel economy, and reliability. When it fails, these systems can become erratic.
Do I need to do any special programming myself?
No. That’s the key benefit of our service. We program the module to your specific vehicle using the VIN you provide. It arrives ready for installation, saving you a trip to the dealer and additional programming fees.
Where is the ECM located on my 2006-2007 Corvette?
On the C6 Corvette, the ECM is located in the engine compartment on the right-hand (passenger) side, near the front of the vehicle. For other GM models, the location can vary (e.g., under the battery or in the air cleaner box).
How do I find and provide my VIN?
Your 17-digit VIN can be found on your vehicle’s registration, insurance card, or on the driver’s side of the dashboard visible through the windshield. Please provide this number to us after your purchase so we can program your module correctly.
Will this part fix my check engine light?
If the check engine light is caused by an internal ECM failure (common codes P0601, P0606, etc.), then yes, this part will resolve the issue. However, you should always have your codes scanned to ensure the problem isn’t with a different sensor or component.
Is this module compatible with other part numbers?
Yes, this ECM, part number 12589297, is a direct replacement for several other GM part numbers, including 12597121, 12603892, and 19210738. We ensure the programming matches your vehicle’s original specifications.
