Expert Mechanic’s Tip: Before installing your new Programmed 12589462 PCM, take a moment to inspect your vehicle’s battery terminals and main engine ground wires. A weak battery or a corroded ground can cause voltage issues that mimic PCM failure and can damage a new unit. Ensuring your electrical system is solid is the best way to protect your investment and guarantee a successful repair.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you place your order, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians will then use this VIN to load the correct, updated GM factory software onto the module before it ships. This makes the unit ready for installation upon arrival.
Will I need to do any additional programming after installation?
In most cases, no further programming is needed. However, some GM vehicles require a Security Relearn procedure (also known as a CASE learn) to sync the new PCM with the vehicle’s anti-theft and crankshaft position sensor systems. This is a simple procedure that can typically be done without special tools and instructions can be easily found online for your specific model.
Where do I find my VIN?
Your VIN can be found on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this compatible with my vehicle?
This module fits a wide range of GM trucks, vans, and SUVs. Please refer to the detailed fitment list on this page and ensure your original part number is 12589462, 12602801, or 89017749 to confirm compatibility.
What if I have questions during installation?
While we are confident in our product, we always recommend that installation be performed by a qualified technician. Proper diagnosis is key to a successful repair. This ensures that all other potential issues (like wiring or sensor faults) have been ruled out first.
