Restore Peak Performance to Your C7 Corvette
As a technician with over two decades of experience under the hood, I know the frustration of chasing intermittent electrical gremlins. Your 2014-2016 Corvette is a precision machine, and when its brain—the Engine Control Module (ECM)—starts to fail, it can cause a host of baffling problems. From a sudden no-start condition in your garage to poor performance and a persistent Check Engine Light, a faulty ECM can sideline your vehicle and your driving enjoyment. This isn’t just a part; it’s the central command center for your engine’s fuel delivery, ignition timing, and emissions systems.
We’re offering a reliable, direct-fit replacement Engine Control Module, part number 12673195. The biggest hurdle in replacing an ECM has always been the expensive and time-consuming programming required at a dealership. We eliminate that step entirely. Simply provide us with your vehicle’s VIN during checkout, and our experts will program the module with the latest, most stable software updates from General Motors. It will arrive at your door ready for installation, saving you hundreds of dollars and significant downtime. This is the smart, efficient solution for getting your Corvette back to running the way it was engineered to.
Case Study: A Tricky Diagnosis
A few months back, a 2015 Corvette Z06 was brought into my bay with a complaint of intermittent stalling at low speeds and a random P0606 (ECM/PCM Processor Fault) code that would come and go. The owner had already replaced the battery and checked the main grounds. We could have spent hours chasing phantom wiring issues, but experience pointed towards the ECM itself. Internal circuit board failures can be heat-sensitive and incredibly difficult to replicate consistently. We installed a VIN-programmed 2014-2016 Corvette ECM, performed the quick crankshaft relearn procedure, and the problem was solved permanently. The customer was back on the road in an afternoon, avoiding a multi-day diagnostic headache.
Is Your Corvette Showing These Signs of ECM Failure?
- ✔ Check Engine Light is on with communication codes (like U0100) or internal processor codes (like P0601, P0606).
- ✔ The engine cranks but refuses to start.
- ✔ Unexplained stalling or rough idling, especially when warm.
- ✔ Noticeable decrease in fuel economy.
- ✔ Transmission shifting issues or erratic behavior.
- ✔ Failure to pass an emissions test.
- ✔ Other modules on the vehicle can’t communicate with the engine computer.
Your Straightforward Corvette ECM Installation Guide
Installing your new 2014-2016 Corvette ECM is a manageable job for a confident DIYer. The module is located in the passenger-side cowl area, under the dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Access the Module: You will need to remove the passenger-side floor mats and potentially some trim panels to gain clear access to the ECM located on the right-hand cowl area, under the dashboard.
- Disconnect and Remove: Carefully unclip and disconnect the electrical connectors. Be gentle, as these plastic clips can become brittle over time. Once disconnected, unbolt the module from its mounting bracket.
- Install the New ECM: Mount the new, pre-programmed module in the same location and securely fasten it. Reconnect the electrical connectors, ensuring they click firmly into place.
- Reconnect the Battery: Reattach the negative battery terminal.
- Final Steps: While the module is programmed to your VIN, a Crankshaft Position System Variation (CASE) relearn procedure may be required with a compatible scan tool to clear certain codes and ensure optimal performance. This is a common final step for this repair.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential. It allows us to load the exact, correct GM-certified software for your Corvette’s specific options, engine, and transmission. This ensures the module works perfectly out of the box, just like one from the factory.
Is this module truly plug-and-play?
Yes, for the most part. The core programming is done, so the engine will start and run. However, for a complete fix and to extinguish all dash lights, a final Crankshaft Variation (CASE) relearn is often necessary. This procedure can be completed by most professional scan tools and many high-end DIY scanners.
Where is the ECM on my 2014-2016 Corvette?
The ECM is located inside the vehicle on the passenger side, mounted to the cowl/firewall area underneath the dashboard. You will need to remove some interior trim for access.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original ECM (e.g., codes P0601-P0606) or a related communication fault, this replacement module is the correct solution. It’s crucial to have your vehicle properly diagnosed to confirm the ECM is the root cause of the problem before ordering.
