Restore Peak Performance to Your C6 Corvette
Is your 2006 or 2007 Corvette suffering from frustrating issues like a persistent check engine light, poor fuel economy, stalling, or a no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer of your vehicle. A faulty ECM can disrupt everything from fuel injection and ignition timing to transmission shifting, leaving your high-performance machine feeling sluggish and unreliable. This replacement Engine Control Module, part number 12603892, is the definitive solution to get your Corvette back on the road, running exactly as it should.
From the Diagnostic Bay
We had a 2007 Corvette in the shop with a ghost of a problem. The owner complained of intermittent stumbling at idle and a random P0300 (Random/Multiple Misfire Detected) code that would appear and disappear. We checked plugs, coils, and injectors—all were fine. After hours of chasing wires, we monitored the injector driver signals from the ECM on a scope. We found that the driver for cylinder 4 would occasionally drop out for a millisecond, just long enough to cause a hiccup but not always long enough to set a specific cylinder misfire code. Replacing the ECM with a correctly programmed unit like this one solved the problem instantly. It’s a reminder that when the basics check out, the brain is often the culprit.
Symptoms of a Failing GM ECM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Misfires or rough idling.
- ✔ Complete no-start or intermittent starting problems.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Erratic automatic transmission shifting behavior.
- ✔ Loss of power and poor overall engine performance.

Frequently Asked Questions
Do I need to program this module?
No. This module comes fully programmed to your vehicle using the VIN you provide at checkout. It is ready to install upon arrival, saving you a costly trip to the dealership.
What is a VIN and where do I find it?
The VIN is your car’s unique 17-digit identification number. You can typically find it on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will any other procedures be needed after installation?
In many cases, a security relearn procedure (also known as a Passlock or anti-theft relearn) may be required. This is a simple procedure that can often be done without special tools and typically involves a sequence of key turns. A Crankshaft Variation Relearn (CASE relearn) may also be necessary, which requires a capable scan tool. Consult your vehicle’s service manual for specific instructions.
How can I be sure my old ECM is the problem?
While the symptoms listed are strong indicators, it is always best to have a qualified technician perform a full vehicle diagnostic. This ensures that other potential issues, such as wiring faults or sensor failures, are ruled out before replacing the ECM.
Is this part compatible with other part numbers?
Yes, this ECM is a direct replacement for several part numbers, including 12589297, 12597121, 12603892, and 19210738. Ordering this part ensures you receive a compatible module for any of these original numbers.
