Restore Peak Performance to Your GM Truck
Is your 2007 Silverado 2500 running rough, stalling, or showing a persistent check engine light? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your engine’s performance, fuel economy, and emissions. A faulty ECM can cause a cascade of frustrating issues, making your reliable truck feel unpredictable. This direct-fit replacement ECM, part number 19210738, is the definitive solution to get your vehicle back on the road and running like new.
From the Diagnostic Bay
We had a 2007 Sierra 2500 with the 6.0L V8 come in with a complaint of intermittent stalling at stoplights and a check engine light that would come and go. The owner had already replaced the throttle body and a few sensors with no luck. Our scan tool showed communication loss with the ECM. After verifying the wiring and power/ground circuits were solid, we knew the issue was internal to the module. Heat cycles over the years had caused a hairline crack in a circuit board trace. Replacing the ECM with a VIN-programmed unit like this one solved the problem instantly. The truck ran smoothly, and the phantom codes were gone for good.
Common Symptoms of a Failing ECM
If you’re experiencing any of the following issues, a failing engine computer is a likely culprit. Don’t continue to chase down sensor or wiring problems when the root cause is the module itself.
- ✔ Persistent Check Engine Light (CEL)
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Drastic decrease in fuel economy
- ✔ Complete no-start condition where the engine cranks but won’t fire
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Performance issues like loss of power or hesitation
- ✔ Inability for a scan tool to communicate with the module

Frequently Asked Questions
Do I need to have this module programmed?
No. We handle all the programming for you before shipment. Simply provide your VIN during checkout or in an email, and the module will arrive ready for installation. This saves you the time, cost, and hassle of a dealership visit.
Is installation difficult?
For most 2007 GM trucks like the Silverado and Sierra, the ECM is located under the battery on the driver’s side. The installation is straightforward for a DIY mechanic. You will need to disconnect the battery, remove the battery and tray, unplug the electrical connectors from the old ECM, unbolt it, and then install the new one in the reverse order. Always disconnect the battery before starting work.
Will this fix my check engine light?
If the check engine light and associated diagnostic trouble codes (DTCs) are caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s always recommended to have a proper diagnosis to ensure the ECM is the root cause and not another sensor or wiring problem.
How do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on the driver’s side of the dashboard, visible through the windshield.
Is any other setup required after installation?
In some cases, a security relearn procedure may be necessary, which can typically be done without special tools. Instructions are widely available online, or you can consult your vehicle’s service manual. For most vehicles, it is a simple plug-and-play process.
