There’s nothing more frustrating than a vehicle you can’t rely on. If you’re dealing with a persistent Check Engine Light, poor performance, erratic shifting, or a no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM).

We offer a straightforward, reliable solution: a quality used Programmed 9355699 PCM that arrives at your door ready for installation.
Common Symptoms & Your Solution
A failing PCM can cause a wide range of confusing issues. You might be experiencing one or more of the following:

- Engine Stalling or Misfiring: The engine may run rough, hesitate on acceleration, or die unexpectedly.
- Transmission Problems: Harsh or delayed shifting, or getting stuck in one gear (limp mode).
- No-Start Condition: The engine cranks but won’t start, often due to no fuel injector pulse or spark.

Expert Insight: Why VIN-Specific Programming is Non-Negotiable
You might be tempted to grab a used computer from a local salvage yard, but this is a common mistake. A PCM from another vehicle is like a key for a different house—it simply won’t work. It contains the VIN and specific operating parameters for the vehicle it came from. Installing it in your truck will result in a no-start condition and communication errors. Our service bridges that gap. By programming the module to your VIN before it ships, we ensure it communicates perfectly with your vehicle’s other systems, just like the original did. This is the secret to a successful and stress-free repair.
Don’t let a faulty computer keep your trusted GM vehicle down. This is your chance to restore its performance and dependability with a quality-tested and correctly configured Programmed 9355699 PCM. Place your order, provide your VIN, and get ready to solve the problem for good.
Frequently Asked Questions
What is a PCM and what does it do?
The Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), is the central computer of your vehicle. It controls all aspects of engine and transmission function, including fuel mixture, ignition timing, and shift points, to ensure optimal performance, fuel economy, and emissions.
Is this a new part?
No, this is a high-quality used part that has been sourced from a salvaged vehicle. Each unit is tested for functionality before being programmed and shipped to you.
How does the VIN programming process work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. We use this number to load the exact, most current GM-approved software and calibration files for your specific make, model, and engine onto the computer before we ship it.
Do I need to do anything after I install it?
In most cases, no. This is a plug-and-play solution. However, some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which is a simple process that can typically be done without special tools. Instructions can be easily found online for your specific model.
Will this fit my vehicle if my original part number is different?
Yes, this module (service number 9355699) directly replaces several other part numbers, including 16266645, 16250279, and 16258815. As long as your vehicle is on the compatibility list, this part will work correctly once programmed to your VIN.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. If the part fails within one year of the purchase date, we will provide a replacement unit.
