The second-generation Jeep Wrangler (TJ) 1997-2006 reintroduced round headlights and adopted coil-spring suspension for a notable comfort gain, powered by the rugged 4.0 straight-six. Even on this analogue-era Jeep, the maintenance reminder stays active after a service until it is reset. Owners here mainly need the oil service reset to clear the change-oil indicator and a general service reminder reset once the interval is complete. As the electronics are basic, the reset is typically a simple ignition-key or dash sequence. Browse the guides below and pick the one matching the work done on your TJ Wrangler.
