Is Your GMC Safari Giving You Headaches?
If you’re dealing with a 2000, 2001, or 2002 GMC Safari that’s suddenly developed a mind of its own, the Powertrain Control Module (PCM) is a very likely culprit. As a tech who’s spent two decades diagnosing these GM vans, I’ve seen it all. You might be experiencing frustrating issues like a crank-no-start condition, random stalling at stoplights, erratic automatic transmission shifting, or a check engine light that throws a bizarre mix of codes that don’t seem related. These are classic signs that the vehicle’s central computer is failing.
Why Does the PCM Fail?
The PCM in your Safari, located conveniently by the battery on the driver’s side, lives a tough life. It’s subjected to constant heat cycles and vibrations. Over 20+ years, the delicate internal circuits, processors, and driver transistors can break down. I’ve personally diagnosed hundreds of these P01/P59 generation modules where the injector drivers fail, causing a misfire on one or more cylinders, or the main processor develops microscopic cracks in its solder joints, leading to a complete loss of communication with the rest of the vehicle.
Expert Pro Tip from a 20-Year Veteran
Before you condemn your PCM, always perform a simple but critical test. Disconnect the main PCM connectors and check for 12V+ battery power and clean, solid grounds on the correct pins using a wiring diagram. I’ve seen more than a few vans towed in with a “bad PCM” that was actually just a corroded ground wire or a blown fuse. A few minutes with a multimeter can save you a lot of time and money. If your powers and grounds are good, but the symptoms persist, the PCM is your next logical step.
The Right Solution: A Pre-Programmed PCM
Simply grabbing a used module from a junkyard won’t work. GM vehicles of this era have a Vehicle Anti-Theft System (VATS) that links the PCM to your specific Vehicle Identification Number (VIN). A mismatched module will result in a no-start condition every time. This is where our service provides the perfect solution. We take the guesswork and hassle out of the repair.
