Restore Your Truck’s Brain, Restore Your Peace of Mind
Is your trusty GMC Yukon, Chevy Tahoe, or work van suddenly running rough, refusing to start, or throwing confusing check engine lights?

We offer the definitive solution: a dependable, used engine computer, professionally programmed specifically for your vehicle, to get you back on the road with confidence.
Common Symptoms & Your Solution
If you’re experiencing issues like a rough idle, stalling, poor fuel economy, or complete no-start conditions, your PCM may be failing. You might also see diagnostic trouble codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error) or P0605 (Internal Control Module Read Only Memory (ROM) Error). This programmed 1998-1999 GMC Yukon PCM 16258815 is the reliable and cost-effective answer to these frustrating problems, restoring your engine’s proper function and communication.

Expert Insight: The ‘Plug & Program’ Advantage
Back in the late 90s, vehicle electronics became significantly more complex. The PCM in your GM truck is the central command center, and unlike older components, you can’t just swap it with another used one. It contains vehicle-specific security information (Passlock/VATS) that must match your keys and BCM. Our pre-programming service handles this critical step for you. By flashing your VIN, we ensure the module is properly configured, drastically simplifying the installation process. While a security relearn procedure may still be required (a simple process you can do yourself), our service eliminates the most expensive and complicated part of the job: dealer-level programming. This is the smartest way to replace your 1998-1999 GMC Yukon PCM 16258815.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it. You can typically find your VIN on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your insurance/registration documents.
Will I need to do anything after installation?
In most cases, you will need to perform a simple security relearn procedure after installation to sync the new PCM with your vehicle’s anti-theft system. This procedure, often called a “CASE Relearn” or “Passlock Relearn,” can typically be done without special tools and instructions can be easily found online for your specific model.
Is this a brand new part?
No, this is a high-quality used computer that has been sourced from a salvaged vehicle. Each unit is inspected to ensure it is in good working condition before being programmed and shipped.
What if my original part number is not 16258815?
This PCM is a direct replacement for several part numbers, including 09355699, 16266645, and 9355699 among others listed in the fitment guide. As long as your vehicle is listed and you provide the correct VIN, we will ensure it is programmed to function correctly for your application.
What does “programmed” mean?
Programming, or “flashing,” involves loading the correct factory software and calibrations for your specific vehicle into the PCM using your VIN. This ensures the engine, transmission, and all related systems operate exactly as the manufacturer intended. Our service includes the latest software updates from GM for your model, which can improve performance and efficiency. A properly programmed 1998-1999 GMC Yukon PCM 16258815 is essential for a successful repair.
