Frequently Asked Questions
What do you need from me to program the PCM?
After you place your order, we simply need you to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We use this to load the correct, updated software for your specific make, model, and engine configuration.
Is this part truly ‘plug and play’?
Yes. Because we program it to your VIN before shipping, it is ready to be installed without any additional programming. In some cases, a ‘security relearn’ procedure may be necessary, which is a simple process that can be done without special tools. We can provide instructions for this.
Will this fix my specific problem?
This 1998-1999 Chevrolet 1500 PCM is the solution for a wide range of electronic and performance issues caused by a failed computer. While proper vehicle diagnosis is always recommended, the symptoms listed above are classic indicators of PCM failure. This unit is designed to correct those specific faults.
What’s the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. ECU (Engine Control Unit) is a general term. ECM (Engine Control Module) typically controls only engine functions. A PCM (Powertrain Control Module) is more integrated and controls both the engine and the transmission. For your vehicle, this part serves as the PCM.
Where is this part located on my vehicle?
On most of the compatible models like the Chevrolet 1500 Pickup, Tahoe, and Suburban, the PCM is located in the engine compartment on the driver’s side, often near the battery or firewall.
