Expert Technician’s Note: As a technician with over two decades of experience, I’ve seen countless issues caused by improperly sourced or non-programmed modules. A generic PCM won’t communicate correctly with your truck’s security, transmission, and ABS systems, leading to a cascade of new problems. Our process of programming the Programmed 89017734 PCM to your specific VIN before it ships ensures that all factory parameters are perfectly matched. It’s the difference between a frustrating weekend of guesswork and a successful, one-time repair.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. The service is completely done for you. We flash the module with your vehicle’s VIN and the latest software before shipping. It arrives ready to install, making it a true plug-and-play solution.
What information do you need from me after I order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module correctly for your specific vehicle configuration.
How do I find my VIN?
You can find your VIN in several places: 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.
Will this fix my vehicle’s specific problem?
This Programmed 89017734 PCM is a direct solution for a failed engine computer, which causes the symptoms listed above. While it resolves a very common point of failure on these GM trucks, you should always ensure your vehicle has been properly diagnosed by a qualified mechanic to confirm the PCM is the issue.
What is a ‘CASE Relearn’ and will I need to perform one?
A CASE (Crankshaft Angle Sensor Error) Relearn may be required after installation to sync the new PCM with your engine’s crankshaft position sensor. This procedure requires a compatible professional-grade scan tool and prevents potential misfire codes. Many vehicles will run fine without it, but for optimal performance, we recommend having it performed by your mechanic after installation.
