Common Symptoms & Your Solution
A failing PCM can cause a host of frustrating and difficult-to-diagnose issues. If you’re experiencing any of the following, this module is your answer:
- Check Engine Light (CEL) Illumination: Often with codes like P0601, P0605, or P0606 indicating internal module failure.
- No-Start or Hard-Start Conditions: The engine cranks but won’t fire up due to lack of fuel or spark command.
- Poor Engine Performance: Rough idling, stalling, misfires, and a noticeable loss of power.
- Erratic Transmission Shifting: Harsh shifts, getting stuck in gear, or failure to shift at all.
- Reduced Fuel Economy: The engine isn’t running efficiently, causing you to spend more at the pump.
- Communication Errors: Your scan tool is unable to communicate with the PCM.
This pre-programmed module is designed to resolve these issues by restoring the critical link between your vehicle’s engine, transmission, and sensors.

An Expert’s Note on VIN Programming
From my 20 years on the shop floor, I can tell you that for these late-90s GM trucks, proper programming is everything. It’s not just about the engine; the PCM controls the transmission, the anti-theft system (Passlock/VATS), and even reads the gear ratio from the rear axle. Simply swapping a used computer from another truck will almost always result in a no-start condition or severe shifting problems. By programming it to your specific VIN, we ensure all those factory parameters are perfectly matched. You’re not just buying a part; you’re buying a complete, ready-to-install solution that saves you the time, money, and headache of a trip to the dealer for programming.
Frequently Asked Questions
Do I need to do anything after I install this PCM?
In most cases, the unit is plug-and-play. However, some GM vehicles of this era may require a simple security relearn procedure that takes about 30 minutes and involves cycling the key. We include instructions for this easy-to-perform procedure.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you can add your VIN to the order notes or simply reply to your order confirmation email. We cannot ship the module until we have your VIN to ensure correct programming.
Is this a new computer?
No, this is a thoroughly tested, used OEM computer that was carefully recovered from a salvaged vehicle. This allows us to provide a dependable, factory-correct part at an accessible price point.
What if my original part number isn’t an exact match to 09366810?
Please check the extensive compatibility list provided. This module, identified by service number 09355699, is the correct replacement for many different original part numbers. The critical factor is our VIN-specific programming, which makes it compatible with your vehicle.
Will this fix my transmission shifting problems?
The PCM is the brain of both the engine and the transmission. If your shifting issues are caused by electronic faults, sensor input errors, or internal computer failure, then replacing your faulty 1998-1999 Suburban 2500 PCM 09366810 is very likely to solve the problem.
