Is your trusted GM truck, van, or SUV suddenly running rough, refusing to start, or throwing confusing check engine lights? A failing Powertrain Control Module (PCM) is often the culprit behind these frustrating and costly issues. Don’t let a faulty computer keep your workhorse off the road. This direct-fit replacement PCM, service number 09355699, is the reliable, plug-and-play solution you need to restore your vehicle’s performance and dependability.
Common Symptoms & Your Direct-Fit Solution
A vehicle’s PCM is its brain, controlling everything from fuel mixture and spark timing to transmission shift points. When it fails, the symptoms can be widespread and unpredictable. If you’re experiencing any of the following, a faulty module is a likely cause:
- Severe rough idle or stalling
- Harsh or erratic automatic transmission shifting
- Complete no-start condition with power to all other systems
- Check Engine Light with communication-related Diagnostic Trouble Codes (DTCs)
- Poor fuel economy and loss of power
- Failure to pass an emissions test
This Programmed 09355699 PCM is engineered to be the definitive fix. We take the guesswork out of the repair by pre-flashing the module with the latest GM-certified software updates specifically for your vehicle. By providing your Vehicle Identification Number (VIN) during checkout, you receive a unit that is ready for installation right out of the box, restoring the precise factory-level control your engine and transmission require.

An Expert’s Note on VIN Programming
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used computer from a junkyard. More often than not, this leads to more problems. Why? Because a PCM from another vehicle is programmed for that specific vehicle’s optionsโits gear ratio, tire size, security system, and more. Installing a mismatched module can cause everything from a persistent check engine light to a vehicle that won’t start at all. Our VIN programming service isn’t just a convenience; it’s a critical step that ensures the Programmed 09355699 PCM you receive is the correct ‘brain’ for your truck, getting the job done right the first time.
Frequently Asked Questions
What is the process after I place my order?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as it is required to program the module correctly for your specific vehicle.
Is this part truly plug-and-play?
Yes, the module comes programmed to your VIN. However, depending on your vehicle’s specific anti-theft system (like Passlock or VATS), you may need to perform a simple security relearn procedure. This procedure can typically be done in your driveway without special tools and instructions are widely available online.
How do I know if the PCM is actually my problem?
While this module fixes all PCM-related failures, it’s crucial to have your vehicle properly diagnosed. A professional mechanic can confirm that the issue is with the computer and not a sensor, wiring, or other component. This ensures you are ordering the correct part for your repair.
My original part number is 16250279. Will this work?
Yes. Part numbers 09355699, 16250279, and 09366810 are often interchangeable service numbers used by GM for the same hardware. Our Programmed 09355699 PCM is a compatible replacement for all the numbers listed in the description.
Do I need to send my old computer (core) back?
No core return is required for this part. You can keep or dispose of your old module at your convenience.
