Is Your 2001-2002 Camaro or Firebird Running Rough?
If you’re the proud owner of an LS1-powered F-Body, you know the thrill of its performance. But when the Powertrain Control Module (PCM) starts to fail, that thrill can quickly turn into a major headache. I’ve seen it countless times in my 20+ years in the shop: a beautiful Camaro or Firebird comes in on a tow truck, refusing to start, or running so poorly it’s undriveable. The symptoms can be confusing and often intermittent, making diagnosis a real challenge for the average owner.
You might be experiencing issues like:
- ✔ A persistent Check Engine Light that won’t go away.
- ✔ The engine cranks but refuses to start.
- ✔ Unexplained stalling, especially when coming to a stop.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Poor fuel economy and a noticeable loss of power.
- ✔ Communication error codes (U-codes) when scanning for faults.
These are all classic signs of a failing PCM. Located behind the passenger-side strut tower, these modules are subjected to years of intense heat and vibration, which eventually takes a toll on their internal electronic components and solder joints. A faulty PCM can disrupt everything from fuel injection and ignition timing to transmission control, effectively crippling your vehicle.
Expert Pro Tip: The VATS Relearn Procedure
After you install this programmed PCM, your Camaro won’t start on the first try. This is normal. Your vehicle’s Vehicle Anti-Theft System (VATS) or Passlock system needs to sync with the new module. In my shop, we do this every day. Simply turn the key to the ‘ON’ position (don’t crank), and leave it for 10-12 minutes, or until the ‘Security’ light on the dash stops flashing and goes out. Then, turn the key off for 10 seconds. Repeat this cycle two more times for a total of three cycles. On the fourth try, the car will start and run perfectly. This simple procedure saves you a trip to the dealer and hundreds of dollars in programming fees.
The Right Solution: A VIN-Programmed PCM
Don’t just grab a used module from a junkyard. It won’t have the correct software for your car’s specific options—like transmission type, gear ratio, or tire size—and it certainly won’t be synced to your vehicle’s anti-theft system. This PCM, part number 12200411, is the definitive solution. We take all the guesswork out of the repair.
Here’s how our process works for you:
