Expert Insight: The Critical Role of VIN Programming
For these late-90s GM trucks and vans, simply swapping a used computer from another vehicle won’t work. These vehicles use a security system (often GM’s Passlock) that is tied directly to the VIN stored in the PCM. Our VIN programming service isn’t just a convenience; it’s essential. We ensure the security information matches your specific key and vehicle, preventing a no-start condition after installation. This process saves you from a costly trip to the dealer and the headache of a vehicle that still won’t run, getting you back to work faster.
Frequently Asked Questions
Do I absolutely need to provide my VIN?
Yes. Providing your Vehicle Identification Number (VIN) is mandatory. We cannot ship the module without it. This step is crucial for programming the 16250279 PCM with your vehicle’s specific software, security information, and operating parameters, ensuring it works correctly right out of the box.
Is this part truly plug-and-play?
Yes, for the vast majority of vehicles listed. Because we program it to your VIN, it should start and run the vehicle without any additional steps. In some rare cases, a Case Relearn Procedure (crankshaft position sensor relearn) may be needed, which can be performed with a capable scan tool.
How do I know for sure that my PCM is the problem?
While the symptoms listed are strong indicators, it’s always best to have a qualified mechanic perform a full vehicle diagnostic. Common PCM failure codes like P0601 (Internal Control Module Memory Check Sum Error) are a definitive sign. Diagnosing the issue correctly before ordering will save you time and money.
What is the warranty on this module?
This unit is backed by our one-year replacement warranty. This covers any defects in the module itself. Please note, it does not cover damage caused by other faulty components on the vehicle, such as a shorted sensor or wiring harness.
Will this computer fix my transmission shifting problems?
In many cases, yes. The PCM controls both engine and transmission functions. If the module is failing, it can send incorrect signals to the transmission, causing erratic shifting, delayed engagement, or failure to shift. If the root cause is electronic, this part is the solution.
Does this part fit other part numbers?
Yes, this module is a direct, programmed replacement for service numbers 16250279, 09366810, and 09355699. Please check your original module to confirm one of these numbers is present.
