Get Your Workhorse Running Right Again
Is your 2006-2007 Silverado, Sierra, Express, or Savana van down for the count? A failing Engine Control Module (ECM) can bring your entire operation to a halt, causing frustrating no-start conditions, poor engine performance, and persistent check engine lights. This isn’t just an inconvenience—it’s lost time and lost income. This direct-fit ECM is the reliable, straightforward solution to get your truck off the lift and back on the road where it belongs. We take the guesswork out of the repair by programming the unit specifically to your vehicle’s VIN before it ships, ensuring a seamless installation process.
Common Symptoms & Your Solution
If your truck is experiencing any of the following, a faulty ECM is a likely culprit. This module is the definitive fix for issues such as:
- Complete no-start or intermittent starting problems
- Check Engine Light with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0606
- Poor fuel economy and reduced engine power
- Erratic transmission shifting or gear indicator behavior
- Stalling or rough idling
Instead of paying for expensive diagnostics and programming fees at a dealership, this unit provides a cost-effective and efficient path to restoring your vehicle’s core functions. This is the central component your Duramax diesel engine needs to operate reliably.

Pro Tip from a 20-Year Tech: Before you replace your ECM, take a moment to check the simple things. On these Duramax trucks, the main engine wiring harness is known to chafe near the alternator bracket. A shorted wire there can mimic ECM failure. Also, verify you have good power and ground connections at the battery and the module itself. If those fundamentals are solid and you still have communication codes, you can be confident that replacing the 2006-2007 GM Diesel ECM is the correct next step.
Frequently Asked Questions
Do I need to have this ECM programmed by a dealer?
No. We handle all the programming for you before we ship the part. All you need to do is provide us with your vehicle’s 17-digit VIN during checkout or by message, and the computer will arrive ready to install.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is very straightforward. On most Silverado and Sierra trucks, it’s located under the battery on the driver’s side. On Express and Savana vans, it’s in the engine compartment. Always disconnect the battery before beginning the installation.
Will this fix my specific problem or check engine light?
If your vehicle’s issues and diagnostic codes point to a faulty engine computer, this part is designed to be the solution. It directly resolves internal module failures that cause communication errors and performance problems.
What information do you need from me after I order?
We only need your complete 17-digit Vehicle Identification Number (VIN). This allows us to program the module with the exact software and calibration file for your truck’s specific options.
What does the one-year warranty cover?
This unit is backed by our one-year replacement warranty. In the unlikely event the module fails within one year of purchase, we will provide a replacement unit to get you back on the road.
