Restore Peak Performance to Your 6.6L Duramax Diesel
The Engine Control Module (ECM) is the central command center for your 2006-2007 GM HD truck or van. It meticulously manages critical engine functions, including fuel injection timing, turbocharger boost pressure, glow plug operation, and emissions systems to ensure your Duramax engine runs with the power and reliability you depend on. When this vital component begins to fail, it can lead to a cascade of frustrating and performance-robbing issues, from a persistent check engine light to a no-start condition that leaves you stranded. A faulty 2006-2007 Silverado ECM can be the hidden cause of problems that are often misdiagnosed, leading to wasted time and money on unnecessary parts.
From the Diagnostic Bay
We recently had a 2006 Sierra 2500HD in the shop with a baffling intermittent stalling problem. The owner had already replaced the fuel filter and checked for air leaks, but the truck would still die randomly, usually after it was fully warmed up. There were no hard codes stored, just a history of lost communication with various modules. After verifying all power and ground circuits to the ECM were solid, we connected a data logger. We saw that just before each stall, the entire data stream from the engine computer would drop out. This pointed to an internal failure in the ECM itself, which was breaking down under heat. Replacing the module with a properly programmed unit like this one completely resolved the issue, getting the owner’s workhorse back on the road reliably.
Is Your GM Diesel Truck Showing These Symptoms?
- ✔️ Persistent Check Engine Light with codes like P0601, P0606, or other internal processor faults.
- ✔️ Engine stalls unexpectedly, idles roughly, or refuses to start at all.
- ✔️ A noticeable decrease in engine power, throttle response, and fuel economy.
- ✔️ Harsh or erratic automatic transmission shifting behavior.
- ✔️ Inconsistent readings from gauges on your instrument cluster.
- ✔️ Your diagnostic scan tool is unable to communicate with the engine computer.

Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. This ECM comes fully programmed to your vehicle’s specific VIN. After you place your order, you will need to provide us with your VIN. We handle all the programming before the part is shipped to you, making it ready for installation right out of the box.
Where is the ECM located on my truck?
On 2006-2007 Silverado and Sierra pickups, the ECM is located in the engine bay on the driver’s side, mounted under the battery tray. On Express and Savana vans, it is typically found in the LH rear or front of the engine compartment.
Will I need to perform a security relearn procedure after installation?
In many cases, a security relearn (also known as a Passlock or anti-theft relearn) will be necessary for the vehicle to start. This is a simple procedure that typically involves turning the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. Instructions can be easily found online for your specific model.
Is this a brand new part?
This is a high-quality, fully tested replacement component that meets or exceeds original equipment specifications. Each unit undergoes rigorous inspection and validation to ensure long-term reliability and performance.
How do I provide my VIN number?
After completing your purchase, please send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your ECM without this information. The VIN can be found on your driver’s side door jamb sticker or on the dashboard viewable through the windshield.
