An Expert’s Insight
As a technician with over two decades of experience, I’ve seen countless late-90s GM trucks sidelined by a bad computer. The original capacitors and board components simply can’t withstand decades of constant heat cycles under the hood. The most common mistake owners make is installing a used, unprogrammed module from a junkyard. This rarely works and can even introduce new, hard-to-diagnose problems. Our process of programming the module to your specific VIN with the latest software is the correct way to do the job, ensuring the engine, transmission, and anti-lock brakes all communicate exactly as the factory intended. It’s the difference between a temporary patch and a lasting repair for your 1998 GMC Savana 2500 PCM or other compatible vehicle.

Frequently Asked Questions
Do I need to send my old computer back?
No, there is no core charge or requirement to return your original module. You can keep it or dispose of it as you see fit.
Is any additional programming required after I install it?
No. This PCM is programmed to your vehicle’s VIN before it ships, making it a true plug-and-play solution. Simply install it, and you’re ready to start the vehicle. In some cases, a security relearn procedure may be necessary, which is a simple process that can be done without any special tools.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot program and ship your module until we receive your VIN.
Where is the PCM located on my vehicle?
On most of the compatible GM trucks, vans, and SUVs from this era, the PCM is located in the engine compartment. It’s typically on the driver’s side (LH) near the battery or on the passenger’s side (RH) fender well, as noted in the compatibility list.
What is the difference between a PCM, ECM, and ECU?
These terms are often used interchangeably. ECU (Electronic Control Unit) is a general term. ECM (Engine Control Module) specifically controls engine functions. PCM (Powertrain Control Module) is the most common term for these GM vehicles, as it controls both the engine and the transmission functions.
