Is Your Truck Running Rough, Stalling, or Refusing to Start?
A failing Powertrain Control Module (PCM) can bring your dependable GM truck or SUV to a dead stop, causing endless frustration and downtime. If you’re dealing with a persistent check engine light, erratic engine behavior, poor fuel economy, or a vehicle that just won’t run right, the problem often lies with the vehicle’s computer. This isn’t just a part; it’s the brain of your engine, and when it fails, nothing works as it should. We offer a straightforward, reliable solution to get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways. You might be experiencing one or more of the following issues:
- Harsh or incorrect transmission shifting
- Engine stalling or misfiring
- Complete no-start condition
- Poor acceleration and loss of power
- Check Engine Light with communication error codes (like P0601, P0605)
- Reduced fuel efficiency
This professionally programmed 1998-1999 Suburban 2500 PCM is the definitive solution to these problems. We take a reliable, tested OEM computer and flash it with the latest official GM software calibrated specifically to your vehicle’s VIN. This ensures that all parameters for your engine, transmission, and factory options are perfectly matched, restoring the performance and reliability you depend on.

- ✔ Optimized Performance: Programmed with the latest GM software updates to address known factory issues, often improving drivability and efficiency over the original software.
- ✔ Cost-Effective Solution: Get a reliable, tested OEM computer without the high cost of a new unit from the dealer.
- ✔ Guaranteed Compatibility: This computer is a direct replacement for multiple part numbers, including 09355699, 16266645, and 9366810, ensuring a perfect fit for the applications listed below.
- ✔ Peace of Mind: This unit is backed by our one-year replacement warranty.
A Note From Our Technicians: The single most important step for replacing a PCM in these GM vehicles is the VIN programming. Unlike a simple sensor, the PCM must know every detail about your truck—from its engine size and transmission type to its axle ratio. A generic, unprogrammed computer will cause immediate running issues or simply won’t work at all. Our process of flashing the unit with your specific VIN ensures it works just like the original, right out of the box. This is the key to a successful and lasting repair.

Frequently Asked Questions
Do I need to do any programming myself?
No. This computer arrives ready for installation. We handle all the programming for you using the VIN you provide, making this a true plug-and-play solution. You will not need to visit a dealer or mechanic for additional programming.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot ship your part until we receive this information, as it is required for the programming process.
Is this a new part?
This is a high-quality, used OEM computer that has been sourced from a salvaged vehicle. Each unit is thoroughly tested to ensure it is fully functional before being programmed and shipped.
What if my original part number isn’t listed?
The part numbers we’ve listed (09355699, 16266645, 9355699, etc.) are interchangeable. As long as your vehicle’s year, make, and model are on the fitment list, this computer will be the correct replacement once programmed to your VIN.
Will this fix my ‘Check Engine’ light?
If the check engine light is caused by a faulty PCM (e.g., internal processor error codes), then this programmed 1998-1999 Suburban 2500 PCM will solve the issue. However, if the light is on due to other failing sensors or components on the vehicle, those issues will need to be addressed separately.
