Expert Insight: As a technician with over two decades of experience, I’ve seen countless late-90s GM trucks sidelined by a failed PCM. The most common culprit is internal circuit board failure due to age, heat cycles, and vibration. Owners often chase down sensors and wiring issues for weeks, only to find the root cause was the computer itself. Installing a pre-programmed module like this Programmed GM PCM 09366810 is the most efficient and reliable repair. It not only fixes the immediate problem but also includes the latest software calibrations from GM, which can correct drivability issues the vehicle had even when it was newer.
Frequently Asked Questions
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). This is essential for us to program the module correctly for your specific vehicle configuration.
Is any additional programming required after installation?
In most cases, no. Our programming service makes this a plug-and-play part. However, some GM vehicles of this era have a security system (Passlock/VATS) that may require a simple key relearn procedure after installation. This procedure can be done without any special tools and typically takes about 30 minutes. We can provide instructions for this process.
Do I need to send you my old PCM?
No, there is no core charge or need to send us your old, faulty module. You can recycle it locally once you’ve confirmed the new part has solved your issue.
How do I find my part number to confirm a match?
The part number is printed on a sticker on your original PCM. You can compare it to the compatible part numbers listed here (16250279, 09366810, 09355699). Even if your number isn’t an exact match, as long as your vehicle’s year, make, and model are on our fitment list, we can program this module for you with your VIN.
Where is the PCM located on my vehicle?
On most of the trucks, SUVs, and vans covered by this part, the PCM is located in the engine bay. On S10 Blazers and Jimmys, it’s typically on the passenger side firewall/fender area. On full-size trucks and vans, it’s often on the driver’s side inner fender, near the battery.
