Is Your Truck or SUV Running Rough? Get It Back in Top Form.
If you’re dealing with a frustrating check engine light, stalling, erratic shifting, or a no-start condition in your GM truck or SUV, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a critical failure that affects performance, fuel economy, and reliability. This replacement PCM is the definitive, hassle-free solution to get your trusted vehicle back on the road, running exactly as it should. We take the guesswork out of the repair by pre-programming this module specifically for your vehicle using your VIN, ensuring it’s ready for a plug-and-play installation right out of the box.
Common Symptoms & Your Solution
A faulty PCM can mimic a wide range of other mechanical problems, leading to costly and incorrect repairs. Before you replace another sensor or component, see if your vehicle is exhibiting these classic signs of PCM failure. This unit is the direct solution for issues like:
- Persistent Check Engine Light (CEL)
- Diagnostic Trouble Codes (DTCs) for internal module failure (e.g., P0601, P0605, P0606)
- Engine stalling or cutting out unexpectedly
- Rough or inconsistent idling
- Harsh or erratic automatic transmission shifting
- Poor acceleration and overall engine performance
- Reduced fuel economy
- Failure to pass emissions testing

Expert Insight: Why VIN Programming is Non-Negotiable
On these late-90s GM vehicles, the PCM is more than just an engine computer; it’s the brain that integrates with the transmission, anti-lock brakes, and the vehicle’s security system (VATS/Passlock). A generic, non-programmed module from a salvage yard will almost certainly result in a no-start condition due to a security mismatch. Our VIN-programming process ensures the replacement module communicates seamlessly with all other systems in your truck, just like the original did from the factory. This is the key to a successful and permanent repair for your 1998-1999 Suburban 1500 PCM 09355699.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you can add your 17-digit VIN to the ‘notes’ section at checkout. If you miss it, we will contact you via email to request the information before we program and ship your module.
Is any additional programming needed after installation?
No, this module is programmed to be plug-and-play. However, for some vehicles, a Crankshaft Variation Relearn (CASE Relearn) may be required to clear a P1336 code and ensure the most accurate misfire detection. This can be done with a capable bi-directional scan tool.
Will this work for my 1998 GMC Sierra with the same part number?
Yes. This 1998-1999 Suburban 1500 PCM 09355699 is also the correct computer for a vast range of GM models from that era, including the Sierra, Silverado, Tahoe, Yukon, Express, Savana, and more, as long as the service number on your original module matches one of the compatible numbers listed (09355699, 16250279, 09366810).
What if my truck has a security system like VATS or Passlock?
Our programming process includes configuring the module to work with your vehicle’s specific security system based on the VIN you provide. This ensures your engine will start and run correctly without any security-related issues.
What is the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECM (Engine Control Module) typically controls only the engine. A PCM (Powertrain Control Module) controls both the engine and the automatic transmission, which is what this unit is. ECU (Electronic Control Unit) is a more generic term for any electronic module.
