Restore Peak Performance to Your GM Truck or SUV
Is your trusty Chevrolet, GMC, or Cadillac suffering from a persistent check engine light, erratic performance, or a no-start condition? The brain of your vehicle’s engine management system, the Powertrain Control Module (PCM), is often the culprit. This isn’t just a replacement part; it’s a complete, ready-to-install solution designed to get your vehicle back on the road with the reliability you depend on. We provide a professionally programmed PCM for 1999 Suburban 1500 and many other GM models, taking all the guesswork and expensive dealership trips out of the equation.
Common Symptoms of a Failing PCM & Your Solution
A failing PCM can cause a wide range of frustrating issues that can be difficult to diagnose. If you’re experiencing any of the following, a faulty module is a likely cause:
- Check Engine Light (CEL) Illumination: Particularly for internal module error codes like P0601, P0602, or P0606.
- Engine Performance Problems: Stalling, rough idling, misfiring, or a sudden drop in fuel economy.
- Starting Issues: The engine cranks but refuses to start, or starts intermittently.
- Transmission Shifting Problems: Harsh or erratic shifting, or getting stuck in a single gear.
- Failed Emissions Test: Inability to pass smog or emissions inspections due to active trouble codes.
This module is the definitive solution. It arrives at your door fully programmed with the latest GM software updates, specifically matched to your vehicle’s unique VIN. This ensures all systems communicate correctly, restoring the smooth operation and efficiency you expect from your vehicle. Getting the correct Programmed PCM for 1999 Suburban 1500 is the critical first step to a lasting repair.

An Expert’s Note: For years, we’ve called the PCM the ‘black box of mystery.’ A failing one can create a cascade of confusing symptoms that send mechanics and DIYers on a wild goose chase, replacing perfectly good sensors and parts. The truth is, the computer itself is often the single point of failure. By replacing it with a properly programmed unit like this one, you’re not just swapping a part; you’re providing a clean slate for your vehicle’s entire electronic system. This is often the fastest and most reliable way to solve those phantom electrical gremlins for good.
Don’t let a faulty computer keep your dependable truck or van sidelined. This is your opportunity to perform a professional-level repair right in your own driveway. By installing our Programmed PCM for 1999 Suburban 1500, you’re ensuring your vehicle serves you reliably for years to come.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. This module is a complete plug-and-play solution. We handle all the programming before we ship it. You will simply need to install it and, in most cases, perform a simple security relearn procedure which takes a few minutes with just your ignition key.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. You can also add it as a note during the checkout process. We cannot ship your part until we have this information to ensure perfect programming.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the existing PCM (like a P0601 code), this module is the correct fix. It’s crucial to properly diagnose your vehicle first to ensure the PCM is the root cause of the problem.
What is the security relearn procedure?
For most of these GM vehicles, it’s a simple process. After installation, you’ll turn the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeat this cycle three times. This allows the new PCM to synchronize with your vehicle’s anti-theft system. The vehicle should then start and run normally.
Is this compatible with part number 16263494?
Yes. This module is a direct replacement for service number 16263494 and the other part numbers listed. We program it to your VIN, making it the correct electronic match for your truck, van, or SUV regardless of the original part number.
