The Ford Puma Mk2 (J2K) 2020-Present revived the Puma name as a stylish compact crossover on the Fiesta platform, complete with its clever MegaBox boot and 48V mild-hybrid assistance. Its modules track maintenance and store calibration baselines that need resetting after servicing. An oil service reset clears the change-oil message, and a service reminder reset removes the maintenance light. You may also need a TPMS reset after a wheel change, a steering angle reset following alignment, and a brake pad wear reset with new pads. Note the mHEV carries a 48V battery under the passenger seat plus a 12V in the engine bay; a renewed 12V cell needs registration. Choose the procedure for your Puma below to reset correctly.
