2006-2007 Corvette ECM 12597121 Programmed Engine Control Module

Restore Your Corvette’s Heartbeat with a Precision-Programmed ECM

As a technician with over two decades of experience under the hood, I know the frustration that comes with a failing Engine Control Module (ECM), especially in a high-performance machine like a 2006-2007 Corvette. Intermittent stalling, a no-start condition, or a dashboard full of warning lights can sideline your C6 and turn your dream car into a driveway ornament. The ECM is the brain of your vehicle, managing everything from fuel injection and ignition timing to transmission shifts. When it fails, performance, reliability, and even safety are compromised.

This isn’t just a replacement part; it’s a complete solution. We take the guesswork and the expensive trip to the dealership out of the equation. Each module is meticulously programmed with the latest official GM software updates, specifically matched to your Corvette’s Vehicle Identification Number (VIN). This ensures seamless integration and restores the precise operational parameters your vehicle was designed with. You’re not just fixing a problem—you’re restoring your car’s factory-spec performance and efficiency.

Is Your Corvette Showing These Telltale Signs?

A faulty ECM can manifest in numerous ways. In my shop, I’ve seen these symptoms countless times. If you’re experiencing any of the following, a failing 2006-2007 Corvette ECM is a likely culprit:

• ✔ Check Engine Light is on with communication codes (like U0100) or internal processor fault codes (P0601, P0602, P0606).
• ✔ The engine cranks but refuses to start.
• ✔ Unexplained stalling or rough idling, even after replacing other components.
• ✔ Noticeable decrease in fuel economy.
• ✔ The vehicle is in “limp mode,” with reduced power.
• ✔ Issues with automatic transmission shifting.

DIY Installation Guide: Get Your Corvette Roaring Again

Replacing the ECM on your C6 Corvette is a straightforward job for a DIY enthusiast. The module is conveniently located in the right-front of the engine compartment. Follow these steps for a successful installation.

1. Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
2. Locate the ECM: Open the hood and find the ECM on the passenger side (RH side) of the engine compartment, near the firewall.
3. Disconnect Connectors: Carefully release the locking tabs on the electrical connectors and pull them straight out from the module. There are typically two large connectors. Avoid forcing them.
4. Remove the Old Module: Unbolt the bracket holding the ECM in place and gently remove the old module from the vehicle.
5. Install the New Module: Seat your new, pre-programmed ECM into the bracket and secure the bolts.
6. Reconnect Everything: Plug the electrical connectors firmly back into the new ECM until they click and lock into place. Reconnect the negative battery terminal.
7. Perform Security Relearn: In most cases, you will need to perform a simple security relearn procedure. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times. This allows the new ECM to sync with your vehicle’s anti-theft system. Consult your owner’s manual for the specific procedure for your car.
