Expert Insight: Why VIN Programming is Non-Negotiable
Back in the late 90s, GM vehicles had dozens of variations for options, security systems (like Passlock/VATS), and emissions equipment. A generic, non-programmed module from a salvage yard simply won’t work. It won’t have the correct software to manage your specific engine, transmission, and anti-theft system, leading to a no-start condition or immediate check engine lights. Our service of using a 16236757 PCM programmed to your exact VIN eliminates this critical failure point, saving you time, money, and the immense frustration of a failed repair.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact software and calibration files your car needs. This includes information about your engine, transmission, tire size, gear ratios, and anti-theft system. Without it, the module will not function correctly.
Will I need to do any additional programming after installation?
In most cases, no. This module arrives ready to install. However, some GM vehicles may require a simple, key-based security relearn procedure that you can do yourself in your driveway. We include instructions for this common procedure if it applies to your vehicle.
Is this the correct part for my car?
This 16236757 PCM programmed unit fits a wide range of 1998-1999 GM models. Please check the compatibility list on this page carefully. The best way to be certain is to match the service number from your original module to one of the numbers listed in our description.
Where is the PCM located on my vehicle?
The location varies. On many of these models, it’s found in the engine compartment inside the air filter box. On others, like the Alero and Grand Am, it is located on the left-hand (driver’s side) center dash area. A quick search for your specific model will confirm its location.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. If the module fails within one year of the purchase date, we will provide a replacement unit.
