Get Your GM Truck or Van Back on the Road, Fast.
Is your trusty Chevrolet or GMC workhorse suddenly stalling, running rough, or refusing to start?

We offer the definitive, hassle-free solution: a reliable, used OEM engine computer, part number 09355699, that arrives at your door fully programmed to your vehicle’s specific VIN.

- Check Engine Light: Persistent and often accompanied by communication error codes (like P0601, P0605, P0606).
- No-Start or Hard-Start: The engine cranks but won’t fire up, or takes an excessive amount of time to start.
- Stalling & Rough Idle: Your vehicle may stall unexpectedly at stops or idle erratically.
- Poor Performance & Fuel Economy: Noticeable loss of power, hesitation during acceleration, and a sudden drop in MPG.

Expert Insight: The End of the Programming Headache
As a technician for over 20 years, I remember the days of swapping modules being a multi-step nightmare. You’d install the hardware, only to have a dead vehicle that needed to be towed to a dealer for expensive programming. Our process eliminates that completely. By programming the module to your VIN before we ship, we hand you the final piece of the puzzle. You’re not just buying a part; you’re buying a complete, ready-to-install solution that saves you time, money, and the stress of coordinating a tow and a dealer appointment. This is how modern vehicle repair should be: simple, direct, and effective.
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential. It allows us to load the exact software calibration that your vehicle’s specific options (engine, transmission, emissions, etc.) require. This step ensures the Programmed PCM 09355699 works perfectly right out of the box.
Is this part difficult to install?
For most of these GM trucks and vans, the PCM is located in the engine bay and is held in by a few bolts and electrical connectors. Installation is typically straightforward for a DIYer with basic tools. The key is to disconnect the battery before you begin. Once installed, simply reconnect the battery and start your vehicle.
My original part number is different. Will this still work?
Yes. This module, service number 09355699, is the correct hardware replacement for all the part numbers listed in the description (e.g., 16266645, 16250279, etc.). As long as your vehicle is on the fitment list, we will program it to function identically to your original.
What if I need to perform a security relearn procedure?
On some GM vehicles of this era, a simple security relearn procedure may be necessary after installation. This can typically be done without any special tools and involves a sequence of turning the key on and off. Instructions are widely available online or in repair manuals for your specific model.
How does the one-year replacement warranty work?
This unit is backed by our one-year replacement warranty. If the module fails within one year from the date of purchase, we will provide a replacement unit. Please keep your original receipt for proof of purchase.
