Expert Mechanic’s Tip: Check Your Grounds!
Before you install your replacement 2002 Jeep Liberty ECM, take 15 minutes to check and clean the main engine and chassis ground connections. A poor ground is a leading cause of ECM failure. A corroded or loose ground cable can create voltage spikes that damage sensitive electronics. Ensure the connections at the battery, engine block, and frame are clean, tight, and free of corrosion. This simple step can prevent a repeat failure and ensure your new computer has a long, reliable service life.
