A Veteran Technician’s Advice

I’ve worked on these GM Vortec engines for over 20 years. A common mistake is grabbing a used computer from a salvage yard. These modules are rarely compatible without proper programming and can cause more issues than they solve. The VIN programming we perform is critical—it tailors the module’s software to your vehicle’s specific engine, transmission, and emissions equipment. Using a properly prepared Programmed 16265035 ECM PCM is the only way to guarantee a correct and lasting repair, getting you back on the road with confidence.

Frequently Asked Questions

Do I need to do any programming myself?

No. This module arrives fully programmed to the VIN you provide. In most cases, it is a simple plug-and-play installation. Some vehicles may require a security relearn procedure, which is a simple process that can be done without special tools and typically takes about 30 minutes.

Where do I provide my vehicle’s VIN?

After you complete your purchase, you will need to send us your 17-digit VIN. We will follow up with instructions on how to provide it. We cannot ship your part until we receive and validate the VIN.

How do I know if my old ECM is truly the problem?

While the symptoms listed above are strong indicators, the best way is through a professional diagnosis. Common fault codes pointing to the ECM include P0601 (Internal Memory Check Sum Error) and P0606 (PCM Processor Fault). A no-start condition combined with a lack of communication with a diagnostic scan tool also strongly suggests a failed module.

Is this compatible with all the vehicles listed?

Yes, this part fits the wide range of GM models listed in the compatibility chart. The key is the part number. By programming the unit to your specific VIN, we ensure it functions perfectly for your exact year, make, model, and engine configuration.

What is your testing process?

Every module undergoes a comprehensive series of tests on a dedicated simulator to verify all circuits, sensor inputs, and driver outputs are functioning correctly before it is programmed and shipped.
