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. This almost always leads to more problems. Why? Because a PCM is not a one-size-fits-all part. It’s programmed with specific information about the original vehicle’s engine, transmission, options, and anti-theft system (VATS/Passlock). Installing an unprogrammed module will result in a no-start condition due to a security mismatch. Our VIN programming service isn’t just a convenience—it’s the essential step that makes this a successful repair, saving you from towing bills, diagnostic fees, and immense frustration. We ensure the Programmed 89017750 PCM you receive is the exact digital match for your vehicle.
Frequently Asked Questions
Do I need to do any additional programming after I install it?
No. This PCM is shipped fully programmed to your VIN and is ready for installation. In most cases, you will only need to perform a simple security relearn procedure, which involves cycling the key in the ignition and takes about 10-15 minutes. We include instructions for this simple process.
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is critical for us to program the module correctly for your specific vehicle configuration.
How do I know if this part will fit my vehicle?
This PCM is compatible with a wide range of GM trucks and SUVs. Please check the service number on your original module to see if it matches 89017750 or any of the other compatible numbers listed (12582605, 12589463, etc.). You can also review the detailed fitment list on this page to confirm your make, model, and year.
What is the difference between an ECM and a PCM?
ECM (Engine Control Module) and PCM (Powertrain Control Module) are often used interchangeably. A PCM controls both the engine and the transmission functions, while an ECM may only control the engine. For the vehicles this part fits, it functions as the PCM, managing the complete powertrain.
Will this fix my specific check engine light codes?
This Programmed 89017750 PCM is the direct fix for internal module failure codes such as P0601 (Internal Control Module Memory Check Sum Error) and other communication-related faults. If your codes are caused by a failing module, this part will resolve them.
