The fourth-generation Jeep Wrangler (JL) 2018-Present modernised the iconic 4×4 with aluminium body panels, an eight-speed automatic, the 2.0-litre turbo and 3.6 Pentastar, and even a plug-in 4xe hybrid later in the run. Whenever you service one, the JL’s electronics keep tracking the previous schedule until you reset them. Owners typically reach for the oil service reset to clear the change-oil message, a maintenance light reset after bigger intervals, and the TPMS reset whenever tyres are swapped or pressures adjusted. The procedures below cover each of these for the JL Wrangler individually, so select whichever matches the work you have just completed.
