Expert Insight: The Critical Role of VIN Programming
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used PCM from a salvage yard. The problem is, that module is a stranger to your car. It’s programmed for a different vehicle’s security system (VATS), transmission, and options. This almost always results in a no-start condition and a tow to a shop. Our process of flashing this programmed 9356741 PCM to your exact VIN isn’t just a convenience—it’s the key to a successful repair, saving you time, money, and headaches.
Frequently Asked Questions
What happens after I place my order?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot ship the module until we have this information. Once we receive your VIN, our technicians will program the module with the latest GM software specific to your vehicle and ship it out to you.
Do I need to do any programming myself?
No. This module arrives fully programmed and ready for installation. In some cases, a security relearn procedure may be required, which is a simple process that can be done without any special tools. Instructions are readily available online for this procedure.
Where do I find my vehicle’s VIN?
Your VIN can be found on a metal plate 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.
How do I know if my old PCM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis from a qualified mechanic is always the best course of action. Common diagnostic trouble codes (DTCs) pointing to a bad PCM include P0601 (Internal Control Module Memory Check Sum Error) and P0605 (Internal Control Module Read Only Memory (ROM) Error).
Is this compatible with my 1998 Buick LeSabre?
Yes, this part is compatible with a 1998 Buick LeSabre with the 3.8L engine, as well as a very wide range of other GM models from 1998 and 1999. Please check the detailed fitment list on this page to confirm compatibility with your specific make, model, and engine.
