Is Your GM Truck or SUV Running Unreliably?
If your trusty 1998 Chevrolet Blazer, GMC Jimmy, or another GM vehicle from that era is suddenly stalling, shifting erratically, or refusing to start, the problem often points directly to a failing Powertrain Control Module (PCM). This component is the brain of your engine, and when it malfunctions, it can cause a host of frustrating and confusing issues, leaving you stranded and questioning your vehicle’s dependability. This pre-programmed PCM is the definitive, cost-effective solution to restore your vehicle’s performance and get you back on the road with confidence.

Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM will arrive pre-programmed to the VIN you provide after your purchase. It is ready for installation right out of the box, though a simple security relearn procedure may be required.
What information do you need from me?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module correctly for your specific make, model, and options.
Is this a new part?
No, this is a high-quality, used OEM computer that has been sourced from a salvaged vehicle and thoroughly tested to ensure it is fully functional and reliable.
Will this fix my check engine light?
If your check engine light is caused by a faulty PCM (e.g., internal processor error codes), then this module will solve the problem. After installation, you should clear all existing codes with a standard OBD2 scanner.
What is a security relearn and is it difficult?
For many GM vehicles of this era, a security relearn (also known as a Passlock or VATS relearn) is necessary to allow the vehicle to start. It is a simple procedure that involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating two more times. No special tools are required, and instructions are widely available online.
Which part number will I receive?
You will receive a module that is a direct hardware equivalent for the part numbers listed, such as 9355699 or 16250279. The crucial part is that it will be programmed specifically for your vehicle’s VIN, ensuring it functions perfectly regardless of the number on the sticker.
