Is your 2004-2005 Silverado or Sierra 3500 suddenly running rough, refusing to start, or throwing confusing check engine lights?

Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to program the ECM with the exact software and calibrations specific to your truck’s engine, transmission, and factory options. This step is crucial for ensuring a true plug-and-play installation and proper vehicle operation.
Is this installation difficult?
The physical installation is straightforward for someone with basic mechanical skills. The ECM is located on the driver’s side, under the battery. After disconnecting the battery, you simply unplug the old module’s connectors and unbolt it, then install the new one. Because we pre-program it, no special tools are needed for software setup.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original ECM (e.g., codes P0601 or P0606), this replacement unit will resolve the issue. It’s always recommended to diagnose the root cause of the light before ordering, but a faulty ECM is a very common failure point.
What is the process after I order?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. Once we receive your VIN, our technicians will program the module. It will then be securely packaged and shipped to you, ready for installation.
Does this part require a security relearn procedure?
In most cases with this specific platform, the vehicle’s security system will relearn the new ECM automatically after a few key cycles. We include simple instructions to guide you through this quick process if it is needed.
