When it fails, the symptoms can seem random and confusing. Our process ensures that the replacement module isn’t just a generic part—it’s a component specifically prepared for your vehicle’s configuration.

Frequently Asked Questions
What do I need to do after I purchase?
After completing your purchase, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship your module without it. You can typically add this as a note during checkout or send it to us in a message referencing your order number.
Is any additional programming needed after installation?
In most cases, no. This PCM is designed to be a plug-and-play solution. However, on some specific models, a security relearn procedure (often called CASE learn or Passlock relearn) may be necessary. This is a simple process that can typically be done without special tools and instructions can be easily found online for your specific model.
Where is the VIN located on my vehicle?
Your VIN can be found on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
How do I know if this part number is correct for my vehicle?
Please check the part number on your original module. This unit replaces part numbers 16265035, 16263494, and 8162634940, among others. You can also use the comprehensive fitment list on this page to confirm compatibility with your make, model, and year.
What is the benefit of getting the latest GM software?
Over time, manufacturers release software updates to fix bugs, improve transmission shifting logic, enhance engine efficiency, and address other issues discovered after the vehicle was built. Programming your module with the latest software ensures your vehicle runs as well or better than it did when it was new.
