Expert Insight from a 20-Year Technician
I’ve seen countless drivers chase their tails replacing sensors and parts, only to find the root cause was the PCM all along. In the early 2000s, these GM computers were the central hub for everything. When they fail, they can send false signals that make a good sensor look bad. The biggest mistake people make is buying a used module from a salvage yard. That used module is still locked to the original vehicle’s VIN and security system, making it a useless metal box until you pay a dealer hundreds to flash it—if they even can. This professionally programmed module skips that entire nightmare. It’s the smart, direct fix that saves you time, money, and a massive headache.

No. That’s the primary benefit of our service. We pre-program the module to the VIN you provide during checkout. It arrives ready for installation in your vehicle.
What is the security relearn procedure?
Most GM vehicles of this era require a simple security relearn to sync the new PCM with your vehicle’s anti-theft system. It’s a key-on/key-off procedure that typically takes about 30 minutes and requires no special tools. We include easy-to-follow instructions with your order.
