Is Your GM Truck or Van Running Rough?
If you’re dealing with a frustrating check engine light, erratic engine behavior, stalling, or even a no-start condition in your 2009 Savana 2500, the Engine Control Module (ECM) is a prime suspect. As a technician with over two decades of experience under the hood, I’ve seen countless GM vehicles sidelined by a failing ECM. It’s the brain of your engine, and when it malfunctions, it can cause a cascade of problems that are often misdiagnosed, costing you time and money on unnecessary parts.
Real-World Diagnosis: A Story From My Shop
“A customer’s 2009 Silverado 2500 with the 6.0L engineโwhich uses this exact same ECMโcame in last week. The complaint was intermittent stalling and a persistent P0606 (ECM Processor Fault) code that would return immediately after being cleared. We checked all the basics: battery voltage was strong, and the grounds to the ECM were clean and tight. This confirmed our suspicion that the module’s internal processor was failing. Instead of a costly tow to the dealer and days of waiting, we installed a VIN-programmed module like this one. The truck started right up, the code was gone for good, and the customer was back to work the same afternoon.”
