Ford Econoline(E150-E450): 2010-18

摘要

SUBJECT VEHICLES: 2010 - 2018 Ford Econoline(E150-E450).RELEARN PROCEDURE? No.SPECIAL TOOLS NEEDED? Yes,TPMS activation tool(204-363). The tire pressure monitoring system(TPMS)monitors the air pressure in the 4 road tires with wheel-mounted tire pressure sensors.The sensors transmit radio frequency signals to the smart junction box(SJB)approximately every 60 seconds when the vehicle speed exceeds 20 mph(32 km/h).If the vehicle is stationary for more than 30 minutes,the sensor will enter into a”sleep mode”and stop transmitting.Each tire pressure sensor transmission is compared against a low-pressure limit(the pressure listed on the vehicle certification label minus 25%,which will be about 6-9 psi).If it is determined that the tire pressure has fallen below this limit,the SJB sends a message to the instrument cluster,which then illuminates the low pressure warning indicator and displays the appropriate message(s)in the message center(if equipped).
