Jeep Wrangler Mk1 (YJ) 1991-1996

The first-generation Jeep Wrangler (YJ) 1991-1996 is instantly recognised by its rectangular headlights, riding on leaf-spring suspension with the 2.5 four or 4.0 straight-six. As a simple, analogue-era 4×4, the YJ has minimal electronics, but an oil change still calls for resetting any service indicator it shows. Owners here mainly need the oil service reset to clear the change-oil reminder and a basic service reminder reset after a full interval. The procedure is short and tool-free given the YJ’s straightforward systems. Select the relevant guide below to reset your YJ Wrangler.
