Restore Your Truck’s Brain and Get Back on the Road
Is your trusty 1999 Suburban 1500 or GM truck running rough, stalling unexpectedly, or showing a persistent Check Engine Light? A faulty Powertrain Control Module (PCM), the vehicle’s central computer, is often the hidden culprit behind these frustrating issues. This direct-fit, professionally programmed PCM is the definitive solution to restore your engine’s performance and get your vehicle back on the road with the reliability you depend on. We take the guesswork out of the repair by flashing the module to your specific Vehicle Identification Number (VIN) before it even leaves our facility.
Common Symptoms & Your Solution
A failing PCM can cause a wide range of problems that can be difficult to diagnose. If you’re experiencing any of the following, a faulty module is a likely cause:
- Persistent Check Engine Light (CEL) with codes like P0601, P0605, or P0606
- Engine misfires or rough idling
- Poor fuel economy
- Harsh or erratic automatic transmission shifting
- Vehicle won’t start or stalls intermittently
- Failure to communicate with diagnostic scan tools
Replacing the old unit with our pre-programmed PCM is the most effective way to solve these issues for good. It arrives ready for installation, saving you a costly trip to the dealership for programming.

A Technician’s Insight: As a tech with 20+ years of experience, I’ve seen countless GMT400 and GMT800-era trucks sidelined by computer failure. The biggest mistake people make is grabbing a used module from a salvage yard, which almost never works due to incompatible software and security settings. A properly programmed 1999 Suburban 1500 PCM is the key to long-term reliability. This isn’t just a replacement part; it’s a complete restoration of your vehicle’s core operating system, ensuring the engine, transmission, and all related sensors work together in perfect harmony.
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming for you. This PCM arrives flashed to your vehicle’s VIN and is ready for installation. You will only need to perform a simple security relearn procedure, which takes about 10-15 minutes and requires only your ignition key.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will contact you via email, or you can add it to the notes section during checkout. We cannot ship your part until we have your VIN.
What is the security relearn procedure?
For most compatible GM vehicles, it’s a simple process: 1) Insert the key and turn it to the ‘ON’ position (don’t start the engine). 2) Leave it on for 10 minutes, or until the ‘Security’ light on the dash turns off. 3) Turn the key off for 5 seconds. 4) Repeat steps 1-3 two more times for a total of three cycles. The vehicle should then start and run normally.
Will this fix my Check Engine Light?
If your Check Engine Light is caused by an internal module failure (common codes include P0601-P0606), then this part will resolve the issue. However, if the light is on for another reason, such as a bad oxygen sensor or a loose gas cap, you will still need to address that separate mechanical problem.
Is this compatible with multiple part numbers?
Yes. This module is a direct replacement for several service numbers, including the most common ID 16263494, as well as 16265035 and 8162634940. Providing your VIN ensures we program it correctly for your specific application.
