This isn’t just an annoyance; it’s the brain of your engine, and when it falters, it affects everything from performance to safety. That’s because on these GM vehicles, the PCM is a critical part of the anti-theft system (PassLock II).
In most cases, it is a direct plug-and-play installation. This syncs the new PCM with the crankshaft position sensor for optimal timing and misfire detection. We take a quality OEM unit and flash it with the latest, most stable software updates from GM.
