An Expert Mechanic’s Tip
Before condemning your ECM, always perform a thorough check of your vehicle’s battery and grounding system. A weak battery, loose terminals, or a corroded ground strap can cause low voltage issues that mimic the symptoms of a failing computer. Ensuring your electrical foundation is solid is a crucial first step in any electronic diagnosis. This simple check can save you time and confirm that you’re replacing the right part.
