Restore Peak Performance to Your GM Diesel Truck
Is your 2006-2007 Sierra, Silverado, or Express/Savana van running poorly? Experiencing frustrating issues like a persistent check engine light, rough idling, stalling, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s Duramax diesel engine, managing everything from fuel injection timing and turbo boost to transmission shifting and emissions controls. When it fails, the entire vehicle’s performance and reliability are compromised.
This is a direct replacement Engine Control Module, part number 19260753 (also compatible with 12588335, 12606126, 12606127, 12603623, 12604137, YNAY), that arrives at your door programmed specifically for your truck or van. We use your Vehicle Identification Number (VIN) to load the latest, most stable GM-certified software, ensuring a seamless installation and restoring your vehicle to its factory specifications. Get your heavy-duty truck back to work without the hassle and expense of a dealership visit.
From the Diagnostic Bay
We had a 2006 Silverado 2500HD towed in that was a chronic no-start. The owner had already replaced the fuel filter, checked for fuel pressure, and even swapped the FICM (Fuel Injection Control Module) with a known-good unit. He was at his wit’s end. After hooking up our diagnostic scanner, we found a ‘U’ code, indicating a loss of communication with the ECM. A visual inspection of the module, located under the battery tray, revealed slight corrosion on the case. We tested the power and ground circuits to the module, which were all good. The final diagnosis was an internal failure of the original ECM. After installing one of our VIN-programmed modules, the truck fired up on the first crank and ran perfectly. It’s a reminder that communication errors are often a direct pointer to the control module itself.
Is Your GM Diesel Exhibiting These Symptoms?
- ✔ Persistent Check Engine Light (CEL) with communication or processor fault codes.
- ✔ Engine cranks but will not start.
- ✔ Poor fuel economy and loss of power.
- ✔ Rough or erratic engine idle.
- ✔ Intermittent stalling for no apparent reason.
- ✔ Transmission shifting issues or harsh engagement.
- ✔ Other warning lights on the dash, such as ABS or security lights.
- ✔ Failure to pass state emissions testing.

Frequently Asked Questions
Do I need to program this ECM?
No. This ECM comes fully programmed to your vehicle’s specific VIN before it is shipped. It is ready for installation right out of the box. Simply provide your VIN in the notes at checkout or reply to our confirmation email.
Where is the ECM located on my 2006 Silverado/Sierra?
On the 2006-2007 classic body style pickups, the Engine Control Module is located in the engine bay on the driver’s side, underneath the battery tray. You will need to remove the battery to access it.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, you should always perform a proper diagnosis to ensure the ECM is the root cause and not another sensor or component.
What is a CASE relearn and will I need to do one?
A CASE (Crankshaft Position System Variation) relearn synchronizes the new ECM with the engine’s crankshaft position sensor. While our programming makes the unit plug-and-play, in some rare cases, a CASE relearn may be required to clear a specific trouble code (P0315). This procedure can be performed with most high-level professional scan tools.
Is this a simple plug-and-play installation?
Yes, for the most part. After we program it, the installation involves disconnecting the vehicle’s battery, removing the old ECM, installing the new one, and reconnecting the battery. It is a direct swap with no modifications needed.
