From the Technician’s Bench: The Critical Role of VIN Programming
Many people don’t realize that a PCM isn’t just a generic partโit’s the brain of your vehicle, tailored specifically to its factory options, engine size, and transmission type. Simply swapping a used module from another vehicle will almost never work and can even cause more problems. That’s why VIN-specific programming is non-negotiable. We handle this critical step for you, ensuring the Programmed GM 89017733 PCM we send is a perfect digital match for your truck or van, just like it came from the factory.
Frequently Asked Questions
Do I need to do any programming after I install it?
No. This module arrives pre-programmed to your VIN. However, depending on your specific vehicle, you may need to perform a simple security relearn procedure (often called Passlock or VATS) which can typically be done without special tools. In some cases, a Crankshaft Variation Relearn (CASE) may be needed, which requires a capable scan tool.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to send it to us. We cannot ship your part until we receive and validate your VIN.
Is this the same as an ECM or an ECU?
Yes. The terms Powertrain Control Module (PCM), Engine Control Module (ECM), and Engine Control Unit (ECU) are often used interchangeably. For most GM vehicles of this era, the PCM controls both the engine and the transmission functions in a single unit.
Will this part fix my check engine light?
This module is the correct solution for codes related to internal module failure, such as P0601 (Internal Control Module Memory Check Sum Error). While it can resolve many other issues, it’s always best to have your vehicle properly diagnosed to confirm the PCM is the root cause of your problem before ordering.
What makes this different from a used part from a junkyard?
A used part from another vehicle will have the incorrect VIN and software, and it will not start or run your vehicle. Our Programmed GM 89017733 PCM is loaded with the correct, updated software for YOUR specific VIN, ensuring it works correctly upon installation.
