Expert Insight: The Groundwork for a Successful Repair
As a technician, I’ve seen countless dollars wasted on parts that weren’t needed. Before you condemn your engine computer, do this one simple check: inspect your main battery terminals, engine block grounds, and chassis grounds. A loose, corroded, or broken ground wire can cause erratic voltage and mimic nearly every symptom of a bad ECM. Ensuring your grounds are clean and tight is the single most important step for any electronic diagnosis. A solid foundation ensures this new 2012 Dodge 1500 3.7L ECM can perform its job perfectly from the moment you install it.
