An Expert’s Note on GM Anti-Theft Systems
As a technician with over two decades of experience, I’ve seen countless DIYers get stuck after installing a non-programmed computer. Many of these 90s GM vehicles use a Passlock or VATS anti-theft system. If the PCM isn’t programmed to recognize your specific key and vehicle, it will disable the fuel system, resulting in a frustrating crank-no-start condition. By ordering a Programmed 09355699 PCM from us, you bypass this entire headache. We handle the complex programming so you can focus on the simple physical installation.
Don’t let a faulty computer keep your reliable truck or van off the road. This is your chance to restore proper function and drivability with a part that is correctly prepared for your exact vehicle. By providing us with your VIN, you are ensuring a seamless repair process. This Programmed 09355699 PCM is the smart, reliable fix you’ve been looking for.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive the VIN, as the programming is a required step.
Is this a new part?
No, this is a high-quality, used OEM part that has been sourced from a salvaged vehicle. Each unit is thoroughly inspected and tested to ensure full functionality before being programmed and shipped.
Will I need to do anything after installation?
In most cases, this is a direct plug-and-play installation. However, on some GM models, a simple security relearn procedure may be required. This procedure does not require special tools and can typically be done in your driveway in about 30 minutes. We can provide instructions if needed.
Will this fix my check engine light?
This PCM will resolve any check engine light and drivability issues that are directly caused by a faulty computer (such as internal processor fault codes). If your vehicle has other mechanical or electrical problems, the check engine light may remain on until those separate issues are addressed.
My original part number is different. Will this still work?
Yes, this PCM is a direct replacement for all part numbers listed in the description, including 16266645, 9355699, 16250279, and others. As long as your vehicle is listed in the compatibility chart, this unit will function correctly once programmed to your VIN.
