Restore Your Vehicle’s Performance with a Reliable, Programmed ECM
Is your 2006-2007 Corvette or other GM vehicle suffering from frustrating issues like a persistent Check Engine Light, rough idling, stalling, or a no-start condition? The Engine Control Module (ECM) is the brain of your engine’s operation, managing everything from fuel mixture and ignition timing to transmission shifts. When it fails, it can cause a wide range of problems that are often misdiagnosed, leading to wasted time and money on unnecessary parts. I’ve seen it countless times in my 20+ years of diagnostics: a vehicle comes in with new spark plugs, coils, and sensors, but the core issue—a faulty ECM—was overlooked.
This isn’t just a replacement part; it’s a complete solution. We take a genuine GM Engine Control Module (compatible with part numbers 19210738, 12589297, 12597121, and 12603892) and professionally program it to your vehicle’s specific Vehicle Identification Number (VIN). This means it arrives at your door loaded with the latest factory software updates from GM, ready for a straightforward installation. You get to skip the expensive trip to the dealership for programming, saving you hundreds of dollars and significant downtime. This is the definitive fix for a failing computer, restoring the crisp performance and reliability you expect from your vehicle.
Case Study: A Tricky Diagnosis
A few months back, a 2007 Silverado 1500 was towed into the shop with a classic no-start. The owner had already replaced the fuel pump, thinking it was the obvious culprit. The truck would crank but never fire. When I connected my scan tool, I couldn’t establish communication with the ECM—a major red flag. Instead of chasing fuel or spark, I went straight to the power and ground circuits for the ECM under the battery tray. They were perfect. This told me the module itself had an internal failure. We installed one of our VIN-programmed ECMs, performed the quick security relearn, and the truck fired up on the first try. It’s a perfect example of how a faulty 2006-2007 Corvette ECM (the same E38 platform) can mimic other component failures, making a reliable, pre-programmed part the smartest fix.
Is Your Vehicle Showing These Symptoms?
- ✔ Persistent Check Engine Light (CEL) that won’t go away.
- ✔ Engine cranks but refuses to start.
- ✔ Unexplained stalling or rough, erratic idling.
- ✔ Noticeable decrease in fuel economy.
- ✔ Transmission shifting harshly or at the wrong times.
- ✔ Diagnostic Trouble Codes (DTCs) pointing to internal module failure, such as P0601, P0602, or P0606.
- ✔ Loss of communication with the ECM (U-codes like U0100).
- ✔ Failed emissions test due to module-related faults.
A Straightforward Guide to Installation
Installing your new ECM is a simple process that most DIY enthusiasts can handle in under an hour. Here’s a general guide; your specific vehicle’s layout may vary slightly.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the ECM: On the 2006-2007 Corvette, the ECM is located in the right-hand (passenger side) engine compartment. On many of the listed trucks and SUVs, it’s under the battery tray on the driver’s side.
- Disconnect Connectors: Carefully release the locking tabs on the wiring harness connectors and pull them straight out from the old module. Never force them.
- Swap the Modules: Unbolt the old ECM from its mounting bracket and set it aside. Secure the new, pre-programmed ECM in its place.
- Reconnect Everything: Firmly plug the wiring harnesses into the new ECM until they click into place. Reconnect your negative battery terminal.
- Perform Security Relearn: Most of these GM vehicles require a simple, tool-free security relearn procedure. Turn the key to the ‘ON’ position for 10-15 minutes (do not start), then turn it ‘OFF’ for 10 seconds. Repeat this cycle three times. On the third cycle, the vehicle should start normally.

Frequently Asked Questions
How do I provide my VIN?
How do I provide my VIN?
After you complete your purchase, you will receive an email with instructions on where to send your VIN. You can also add your VIN to the ‘notes’ section during checkout. We cannot program and ship your module without it.
Is this part truly plug-and-play?
Yes! Because we program the ECM with the latest GM software matched to your VIN, it is ready to install. The only additional step for most vehicles is a simple, 30-minute security relearn procedure that requires no special tools.
Will this fix my specific problem?
This module is a direct replacement for a failed factory ECM. If your vehicle is exhibiting the symptoms listed above and has been properly diagnosed with a faulty ECM, this part is the correct solution. It will not fix issues caused by other failing sensors or mechanical problems.
Does this ECM come with a warranty?
Yes, all of our engine control modules come with a warranty. Please see the warranty tab on this product page for complete details and duration.
What if my part number is slightly different?
This module is a direct replacement for part numbers 12589297, 12597121, 12603892, and 19210738. As long as your original module’s part number is on this list, this unit is compatible with your vehicle.
