Expert Mechanic’s Insight
As a tech with over 20 years on the floor, I’ve seen countless headaches caused by improperly matched control modules. On these late 90s/early 2000s GM vehicles, the VIN is critical. It’s not just about engine parameters; it’s tied to the anti-theft system (VATS/Passlock) and specific vehicle options. Using a generic, non-programmed module often results in a no-start condition that leaves you stranded. Getting a programmed 16263494 PCM that’s flashed to your specific VIN is the only way to guarantee a smooth, successful repair without needing advanced scan tools for a security relearn procedure.
Frequently Asked Questions

After you place your order, we simply need you to provide your vehicle’s 17-digit VIN. We will email you with instructions. This allows us to program the module specifically for your truck or van, ensuring a perfect match.
Is this module difficult to install?
Installation is straightforward for anyone with basic mechanical skills. It typically involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in reverse order. Since our programmed 16263494 PCM arrives ready to go, no further programming is required.
Will this fix my vehicle’s security/anti-theft light?
