Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to flash the PCM with the exact software and calibrations for your vehicle’s specific engine, transmission, and factory options. This is essential for proper function and to ensure compatibility with your anti-theft system.
Is this a simple plug-and-play installation?
Yes, for the most part. The module is programmed to be ready to install. However, some GM vehicles may require a simple “security relearn” procedure after installation, which can typically be done without special tools and involves a sequence of key turns. We can provide instructions for this common procedure.
Will this fix my specific problem?
This PCM will correct issues directly caused by a faulty engine computer. While the symptoms listed are strong indicators of PCM failure, we always recommend a proper diagnosis by a qualified mechanic to rule out other potential causes, such as wiring or sensor issues.
What does “used” condition mean?
This is a genuine, factory-original (OEM) part that has been carefully removed from a salvaged vehicle. Each unit is inspected and tested to ensure it is fully functional before being programmed and shipped. This is a reliable alternative to a costly new part.
What is covered by the one-year replacement warranty?
The one-year replacement warranty covers the part itself. If the module fails within one year of the purchase date, we will provide a replacement unit. It covers defects in the part, not issues caused by incorrect installation or other vehicle faults.
