A Veteran Technician’s Insight: I’ve seen it a hundred times. A customer brings in a late-90s GM truck that just won’t run right. They’ve thrown parts at it—sensors, plugs, wires—with no luck. The problem is often the original computer slowly failing. Grabbing a used one from a salvage yard is a gamble; it won’t have the right programming for the vehicle’s anti-theft system (VATS/Passlock) or specific options. This is why a VIN-programmed 16263494 PCM is the only way to do the job right. It eliminates the guesswork and ensures the vehicle communicates with its new ‘brain’ correctly, saving you time, money, and headaches.
