An Expert’s Note on PCM Programming
As a technician with over two decades of experience, I’ve seen countless vehicle issues caused by improperly matched control modules. Simply swapping a used computer from another vehicle rarely works and can even cause new problems. The critical step is the programming, which syncs the module to your vehicle’s specific options, security system, and powertrain. Our process of using your VIN to load the correct, updated GM software ensures this programmed 89017749 PCM communicates flawlessly, just as a new one from the factory would. This isn’t just a part; it’s a complete, reliable repair solution.
Frequently Asked Questions
Do I need to do anything after I install the module?
In many cases, you may need to perform a simple security relearn procedure, also known as a CASE relearn or anti-theft relearn. This can typically be done without special tools and involves a sequence of key cycles. Instructions are widely available online for your specific GM model.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can add your VIN to the order notes or reply to your order confirmation email. We must have your VIN to program the module before we can ship it.
Is this the correct part for my vehicle?
Please review the detailed fitment list on this page. The best way to ensure compatibility is to match the part number from your original module to 89017749 or one of the alternate numbers listed (12589462, 12602801).
What if my original part number is different but on the list?
GM often uses several part numbers for the same component. If your original part number is listed as compatible (like 12589462 or 12602801), this module will function as a direct replacement once we program it for your vehicle.
What exactly does ‘VIN-programmed’ mean?
It means we use specialized equipment to load your vehicle’s unique factory software and calibrations onto this module using the VIN you provide. This makes the computer a plug-and-play component for your specific car or truck, ensuring all systems work correctly.
