Restore Peak Performance to Your GM Truck or Van
Is your truck suffering from erratic behavior, poor fuel economy, or a persistent check engine light? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your engine’s performance. This genuine OEM PCM, service number 16250279, is the definitive solution to restore your vehicle’s reliability and drivability. Sourced from a salvaged vehicle, each unit is meticulously tested and prepared for its next life.
Unlike a generic part from a local store, this module is not just a replacement; it’s a complete, plug-and-play solution. We professionally program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures seamless communication between the engine, transmission, and other onboard systems. Furthermore, we flash it with the latest GM factory software updates, which often correct underlying drivability issues that were present even when the vehicle was new. This means you’re getting a component that’s not only matched to your truck but also contains the most refined operational logic available from the manufacturer.
From the Diagnostic Bay
I once had a 1999 Chevy Tahoe in the shop with a frustrating, intermittent stalling issue. The owner had already replaced the fuel pump, ignition coil, and crank sensor, spending hundreds of dollars with no fix. After connecting our scan tool, we noticed erratic data from the PCM. Instead of throwing more parts at it, we swapped in a VIN-programmed module just like this one. The truck fired up instantly and ran perfectly. It’s a powerful reminder that the PCM is the brain, and when it’s not healthy, the whole system suffers. A correct diagnosis and a properly programmed module can save you time, money, and a lot of headaches.
Why Choose Our Programmed 1998 S10 PCM?
The PCM is the heart of your vehicle’s electronic system, controlling everything from fuel mixture and ignition timing to transmission shift points and emissions. A failing module can cause a cascade of problems that are often misdiagnosed as sensor or mechanical failures. By replacing your faulty unit with our pre-programmed module, you are addressing the root cause of these issues directly. This unit is a direct replacement for multiple part numbers, including 09355699, 16266645, 9355699, 16250279, 16258815, 09366810, and 9366810, making it a versatile fix for a wide range of GM trucks and vans from the era.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Rough or inconsistent idling.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Complete no-start or no-spark condition.
- ✔ Failure to pass state emissions testing.
Don’t let a faulty computer keep your reliable GM truck off the road. Our VIN-programmed PCM is the most effective and straightforward way to solve complex electronic issues. Simply provide your VIN after purchase, and we’ll handle the complex programming. Installation is as simple as disconnecting the battery, swapping the modules, and reconnecting the battery. In some cases, a simple security relearn procedure may be required, which can be done without special tools. Get your vehicle running like it should with this reliable, ready-to-install solution.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM) is your vehicle’s main computer. It controls all aspects of engine and transmission operation to ensure optimal performance, fuel economy, and emissions.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the module until we receive this information, as the programming is essential for it to work in your truck.
Is this a new part?
No, this is a high-quality, used OEM part that has been sourced from a salvaged vehicle. Each unit is tested for functionality before being programmed and shipped.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM, then yes, this part will resolve the issue. However, it’s crucial to ensure your vehicle’s problem has been properly diagnosed, as the light can be triggered by many other failing components.
Do I need to do anything after installing this 1998 S10 PCM?
This module is sent programmed for a plug-and-play installation. In some vehicles, a security relearn or Crankshaft Variation (CASE) relearn procedure may be necessary. This can often be done without a scan tool, and instructions are widely available online for your specific model.
