Is Your Duramax Truck Down for the Count? Get it Running Strong Again.
There’s nothing more frustrating than a powerful truck that won’t start, runs rough, or throws confusing error codes. Your 2006-2007 GM diesel is a workhorse, and downtime costs you time and money. A failing Engine Control Module (ECM) is often the hidden culprit behind these issues, causing everything from poor performance to a complete no-start situation. This VIN-programmed ECM is the definitive solution to get your truck back on the road and running with factory-fresh precision.
Common Duramax ECM Failure Symptoms & Your Solution
If your truck is experiencing any of the following, a faulty computer is the likely cause. This unit is designed to be the direct, reliable fix for these exact problems:
- Engine cranks but will not start
- Intermittent stalling or shutting off while driving
- “Reduced Engine Power” message on the dash
- Erratic or harsh transmission shifting
- Diagnostic trouble codes (DTCs) that won’t clear, especially communication codes like U0100
- No communication with the ECM using a scan tool
- Poor fuel economy and sluggish performance

Frequently Asked Questions
Do I need to program this ECM?
No. This ECM comes fully programmed to your vehicle’s VIN before it ships. It is ready for installation right out of the box.
How do I provide my VIN number?
After you complete your purchase, you can add your VIN to the order notes or reply to your order confirmation email. We will contact you if we do not receive it.
Will this fix my ‘Reduced Engine Power’ message?
A failing ECM is one of the most common causes of the ‘Reduced Engine Power’ message on these trucks. While other sensors can cause this, if you have eliminated other possibilities, this module is the likely solution.
Is any other procedure needed after installation?
In some cases, a simple security relearn procedure (often called a ‘key-cycle relearn’) may be required, which takes about 30 minutes and does not require any special tools. Instructions are readily available online for your specific model.
Does this part fit other trucks besides the Sierra?
Yes. This 2006-2007 Sierra 2500 ECM is also the correct computer for the equivalent year Chevrolet Silverado 2500/3500, Express, and Savana vans with the Duramax diesel engine. Please check the fitment list to confirm.
