Is Your GM Truck or SUV Acting Up? Get a Permanent Fix.
If you’re dealing with a persistent Check Engine Light, rough idling, erratic shifting, or even a frustrating no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM). As the brain of your vehicle’s engine and transmission, when the PCM starts to fail, it can cause a cascade of confusing and costly issues. I’ve seen it hundreds of times in my shop: a 2005 Silverado 1500 comes in stalling randomly, or a 2004 Tahoe won’t communicate with the scan tool. After confirming the wiring and power/ground circuits are solid, the culprit is almost always an internal fault in the PCM.

Expert Pro Tip from a 20-Year Tech
Before you install your new PCM, take a moment to inspect the electrical connector harnesses on your vehicle. Over the years, the pins can develop a thin layer of corrosion, or the weather seals can become brittle. I recommend using a quality electronics cleaner and a small nylon brush to gently clean both the male and female pins. A clean, solid connection is critical for the PCM to function correctly and will prevent future communication errors that can mimic a faulty module.
