Is Your SSR Driving You Crazy?
If your 2003 Chevrolet SSR is suddenly plagued with bizarre issues like a persistent check engine light, rough idling, stalling, or even a complete 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 create a cascade of confusing and frustrating symptoms. You might be chasing ghost codes or replacing perfectly good sensors with no improvement.
Expert Pro Tip: Check Your Connectors First
Before condemning your PCM, take a moment to inspect the electrical connectors on the module itself. Over the years, I’ve seen countless cases where corrosion or a loose pin on the harness connector was the real culprit, causing intermittent communication errors that mimic a bad PCM. A quick clean with a contact cleaner and ensuring a snug fit can sometimes save you from an unnecessary replacement. It’s a 5-minute check that has saved my customers hundreds of dollars.
