Enlarged air pressure monitoring warning system, used on a Reiwa 1st year model Toyota Prius 50 Series (late model) S Touring. This product is likely discontinued. It was functioning normally without any errors until removal. Installation is easy, just remove the steering column cover and insert it into the ABS coupler. It's not an OBD type, so it can be installed neatly without looking like an aftermarket addition. Instruction manual included. Everything in the photos is included. Thank you.
