An Expert’s Note on Programming
As a technician with over two decades of experience, I’ve seen countless vehicle issues caused by improperly sourced or un-programmed control modules. A PCM is not a simple part you can just swap. It contains critical security data (like the anti-theft system) and vehicle-specific operating parameters. Installing a generic, un-programmed GM 89017750 PCM will almost always result in a no-start condition. Our VIN-programming service eliminates this entire headache, saving you time, money, and the frustration of a job half-done. We ensure the brain of your engine is a perfect match for the body.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We must have this number to program the module correctly before we can ship your order.
Is any additional programming needed after I install it?
In most cases, no. Our VIN programming covers the engine and transmission operating systems. However, on some vehicles, a simple security relearn procedure (often called a CASE relearn or anti-theft relearn) may be required, which can typically be done without special tools. Instructions are widely available for this process.
What’s the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECU (Electronic Control Unit) is a general term for any computer in a vehicle. ECM (Engine Control Module) specifically controls the engine. PCM (Powertrain Control Module) is the most common term for modern GM trucks, as it controls both the engine and the transmission functions in a single unit.
How can I be sure this fits my exact truck or SUV?
This module fits a wide range of GM vehicles. The best way to confirm compatibility is to match the service number on your original module to one of the numbers listed (e.g., 89017750, 12602802). Providing us with your VIN during the programming process serves as a final, definitive check for perfect compatibility.
What are the most common signs of a failing GM 89017750 PCM?
The most definitive sign is an internal processor fault code, such as P0601 or P0606. Other common symptoms include unexplained stalling, harsh shifting between gears, multiple unrelated trouble codes appearing at once, and a complete loss of communication with the module when using a scan tool.
