Expert Insight: The Critical Role of VIN Programming
Many people try to save a few dollars by installing a used PCM from a junkyard. This almost always results in a no-start condition. Why? Your vehicle’s security system, often called the Vehicle Anti-Theft System (VATS) or Passlock, is tied directly to the original PCM’s programming. A module from another vehicle won’t have the correct security credentials, and the system will prevent the engine from starting. Our VIN programming service ensures the module we send you is a perfect digital handshake for your truck, making the installation process as simple as possible.
Don’t let a faulty computer keep your hard-working truck off the job. This is the most effective and efficient way to solve complex electronic issues and ensure your vehicle runs as it should. Order your 1997 GM truck PCM 16229684 today and fix it right the first time.
