Restore Peak Performance to Your GM Truck or SUV
Is your 1998-1999 Suburban 2500, Tahoe, Yukon, or pickup truck suffering from frustrating issues like a persistent check engine light, rough idling, stalling, or poor fuel economy? These are classic signs of a failing Powertrain Control Module (PCM). The PCM is the brain of your vehicle, managing critical engine and transmission functions. When it falters, the entire vehicle’s performance and reliability are compromised. This isn’t just an annoyance; it can lead to more significant engine damage if left unaddressed.
From the Diagnostic Bay
I once had a ’99 Tahoe in the shop with a ghost of a problem. The owner had replaced the throttle position sensor, the MAF sensor, and even the fuel pump, but it would still randomly stall at red lights and hesitate on acceleration. After hours of chasing wires, we finally hooked up a scope to the PCM outputs. We found intermittent signal drops that weren’t setting a specific code. We swapped in a known-good, properly programmed PCM, and the truck ran like it just rolled off the assembly line. It’s a powerful reminder that sometimes the issue isn’t a sensor, but the computer interpreting the data.
The Direct-Fit Solution: A Programmed 1998-1999 Suburban PCM
Don’t let a faulty computer keep you off the road. This genuine, used OEM Powertrain Control Module is the reliable and cost-effective solution you need. We take the guesswork and hassle out of the repair by pre-programming the module specifically for your vehicle using your VIN. This ensures that all factory settings, transmission shift points, and engine parameters are perfectly matched to your truck’s original specifications. We also flash it with the latest available GM software updates, which can resolve many factory-known bugs and improve overall performance and drivability.
Common Symptoms of a Failing PCM:
- ✔ Check Engine Light (CEL) is illuminated
- ✔ Engine stalling or misfiring
- ✔ Rough or erratic idling
- ✔ Poor acceleration and loss of power
- ✔ Decreased fuel efficiency
- ✔ Harsh or incorrect automatic transmission shifting
- ✔ Vehicle fails to start intermittently or at all
- ✔ Communication errors with diagnostic scan tools
Why Choose Our VIN-Programmed Module?
Getting a replacement PCM from a dealership can be incredibly expensive, and buying a used one from a salvage yard without programming is a gamble. Our service provides the best of both worlds. You get a dependable, factory OEM part that has been thoroughly tested and is ready for installation right out of the box. Simply provide your vehicle’s VIN after purchase, and our technicians will handle the complex programming process. This saves you a trip to the dealer and the high cost of their programming services. After installation, a simple security relearn procedure (often called a Passlock or CASE relearn) may be required, which can typically be done without special tools.
This module is a direct replacement for multiple part numbers, including 16258815, 09355699, 16266645, 9355699, 16250279, 09366810, and 9366810.

Frequently Asked Questions
Do I need to do anything after installing this PCM?
Yes, in most cases, you will need to perform a security relearn procedure (also known as a Passlock or anti-theft relearn). This procedure syncs the new computer with your vehicle’s anti-theft system and can often be done without any special tools. Instructions are widely available online for your specific model.
How do I provide my VIN for programming?
After you complete your purchase, we will send you a message requesting your vehicle’s 17-digit VIN. You can also add it as a note during checkout. We cannot ship the module until we have your VIN to program it.
Is this a new computer?
No, this is a thoroughly tested, used OEM (Original Equipment Manufacturer) computer sourced from a salvaged vehicle. This ensures factory-level quality and compatibility, unlike many aftermarket alternatives.
My original part number isn’t 16258815. Will this still work?
This module is a direct replacement for several part numbers, including 09355699, 16266645, and others listed in the description. As long as your original part number is on our cross-reference list, this unit will function correctly in your vehicle once programmed to your VIN.
What tools are needed for installation?
Basic hand tools, such as a socket set, are typically all that’s required to physically replace the module. It is usually located in the engine bay and is held in by a few bolts with electrical connectors. Always disconnect the battery before starting the installation.
