Expert Mechanic’s Tip: From my 20 years on the shop floor, I can tell you that many PCM failures are caused by underlying electrical issues. Before installing your new module, take 10 minutes to inspect and clean your battery terminals, check the main engine ground straps for corrosion, and ensure the wiring harness near the old PCM isn’t damaged or frayed. A little preventative maintenance goes a long way in protecting your investment and ensuring a lasting repair for your 2001-2002 GMC 3500 PCM.
