From the Technician’s Bench: Why VIN Programming is Non-Negotiable
As a tech with 20+ years of experience, I can’t stress this enough: you can’t just pull a computer from another truck and expect it to work. On these GM vehicles, the PCM is tied directly to the anti-theft system (VATS/Passlock) and has specific fuel and timing maps for your exact engine and transmission combination. A mismatched module will result in a no-start condition, every single time. By providing us your VIN, you’re ensuring the Programmed PCM 16263494 we send you is a perfect electronic match, saving you the headache of a vehicle that’s still dead in the driveway after the repair.
Don’t let a bad computer keep your workhorse out of commission. This module is the correct, reliable fix for a huge range of hardworking GM trucks, vans, and SUVs from the late 90s and early 2000s. After you complete your purchase, simply send us your vehicle’s VIN, and we’ll handle the rest. Your Programmed PCM 16263494 will ship out ready to restore the heart of your vehicle.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module comes fully programmed to the VIN you provide. The only procedure you may need to perform after installation is a security relearn, which is a simple process that takes about 30 minutes and does not require any special tools. We include instructions for this.
How do I provide my VIN?
After you place your order, you can send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information.
Is this the same as an ECM or an ECU?
Yes. The terms Powertrain Control Module (PCM), Engine Control Module (ECM), and Engine Control Unit (ECU) are often used interchangeably for this part. It is the main computer that controls your vehicle’s engine and often the transmission as well.
What is the most important step during installation?
Always disconnect the vehicle’s battery before removing the old module and installing the new one. This prevents any risk of electrical shorts that could damage the new computer or other vehicle components.
How can I be sure this fits my vehicle?
Please check the extensive fitment list provided on this page. This module replaces several part numbers, including 16263494 and 16265035. As long as your vehicle is on the list and requires one of these part numbers, this module is the correct fit.
