Get Your Dependable GM Truck Back on the Road
Is your trusty GM truck, van, or SUV suddenly unreliable? If you’re dealing with frustrating issues like a no-start condition, rough idling, poor fuel economy, or a check engine light that won’t go away, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a problem that can sideline your workhorse indefinitely. We offer the straightforward, effective solution to get you back in the driver’s seat with confidence.
Common Symptoms & Your Solution
A faulty PCM can cause a wide range of confusing symptoms. If your mechanic is pulling their hair out or you’re tired of guessing, see if these issues sound familiar:
- Check Engine Light: Especially with communication error codes or internal module failure codes (e.g., P0601, P0605).
- No-Start or Hard-Start: The engine cranks but refuses to start, or only starts after many attempts.
- Poor Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel efficiency.
- Erratic Shifting: The transmission may shift harshly, at the wrong times, or not at all.
- Stalling: The engine randomly shuts off while driving or idling.
This pre-programmed engine computer is the definitive fix for these problems. By replacing your old, failing module with this reliable unit, you’re not just swapping a partโyou’re restoring your vehicle’s core operational stability. This is the exact programmed 1999 Suburban 1500 PCM you need to solve these issues correctly the first time.

An Expert’s Diagnostic Tip
From over 20 years in the garage, I’ve seen countless technicians and DIYers chase ghosts, replacing perfectly good sensors and ignition parts when the PCM was the real issue. A failing module can send out false signals, making you think you have a bad throttle position sensor or a faulty ignition coil. Before you spend another dollar on parts that don’t fix the problem, consider the brain of the operation. Installing a properly programmed 1999 Suburban 1500 PCM often resolves a whole host of seemingly unrelated electronic issues, saving you time, money, and immense frustration.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive this information, as the programming is specific to your vehicle.
Is any additional programming required after I install it?
No dealership programming is needed. However, on most of these GM vehicles, you will need to perform a simple security relearn procedure, also known as the CASE relearn. This can typically be done in your driveway with just the key and takes about 30 minutes. Instructions are widely available online for your specific model.
How can I be sure this part will fit my vehicle?
The best way to ensure compatibility is to match the service number from your current module to one of the numbers listed: 09355699, 16266645, 16250279, 16258815, 09366810, or 9366810. You can also check the detailed fitment list on this page. If you’re still unsure, feel free to contact us with your VIN.
Is this a new part?
No, this is a high-quality, tested used OEM part that was carefully recovered from a salvaged vehicle. This allows us to provide a reliable, factory-spec part at an excellent value.
What does the one-year replacement warranty cover?
The warranty covers the module itself. If the unit fails due to an internal defect within one year of the purchase date, we will provide a direct replacement. It does not cover labor costs or damage caused by improper installation or other vehicle faults.
Don’t let a bad computer keep your reliable GM off the road. Order your programmed 1999 Suburban 1500 PCM today and restore the performance and dependability you count on.
