Restore Peak Performance to Your GM Truck or Van
Is your trusty GMC Savana, Chevy Express, or Pickup truck suffering from frustrating issues like a persistent check engine light, erratic shifting, or a no-start condition? A failing Powertrain Control Module (PCM) is often the culprit behind these perplexing problems. This isn’t just a replacement part; it’s the definitive solution to get your vehicle back on the road, running with the reliability you depend on. We professionally program this module to your vehicle’s specific VIN, ensuring it’s ready for installation right out of the box, saving you from a costly and time-consuming trip to the dealership.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a faulty PCM is the likely cause. This module is engineered to resolve these issues:
- Check Engine Light (CEL) with communication-related codes (e.g., P0601, P0605)
- Harsh or incorrect transmission shifting
- Engine stalling, stumbling, or poor fuel economy
- Complete no-start condition where the engine cranks but won’t fire
- Apparent loss of spark or fuel injector pulse
By replacing your old module with this pre-programmed unit, you’re installing a reliable, long-term fix.

An Expert’s Note on These GM Modules
As a technician, I’ve seen countless GMT400-era trucks and vans with PCM issues. After two decades, the internal electronic components, like capacitors and solder joints, can degrade from heat cycles and vibration. This leads to the intermittent and confusing symptoms you might be chasing. Instead of spending hours on diagnostics, replacing the PCM is often the most direct path to a fix. Getting a unit that’s pre-programmed to the VIN, like this 1998 GMC Savana 1500 PCM 09355699, eliminates the biggest installation hurdle and restores the vehicle’s core operational integrity.
Frequently Asked Questions
Do I need to have this programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. This allows for a straightforward installation without the need for expensive dealer-specific tools.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is essential for the programming process.
Is any other procedure needed after installation?
In many cases, you may need to perform a simple security relearn procedure, often called a Passlock or VATS relearn. This can typically be done without special tools and involves a sequence of turning the key on and off. Instructions are widely available online for your specific model. A Crankshaft Variation Relearn (CASE) may also be needed for optimal performance, which requires a capable scan tool.
What if my original part number doesn’t match exactly?
This module is a compatible replacement for several part numbers, including 16250279 and 09366810. As long as your vehicle is on the compatibility list, our VIN-based programming ensures it will function correctly as a replacement for your 1998 GMC Savana 1500 PCM 09355699 or its equivalents.
Where is the PCM located on my vehicle?
On most of the compatible trucks, SUVs, and vans from this era, the PCM (or ECM) is located in the engine compartment, typically on the driver’s or passenger’s side inner fender, often near the battery.
