SUBJECT VEHICLES: Fiat 500 Series 2012-2018 RELEARN PROCEDURE? No. SPECIAL TOOLS NEEDED? A RKETPMS analyzer can be used to determine the sensor’s frequency without having to demount the tire.
T
he tire pressure monitoring system (TPMS) of the 2012-2018 Fiat 500 Series uses wireless technology with wheel rim mounted electronic sensors to monitor tire pressure levels. Sensors, mounted to each wheel as part of the valve stem, transmit tire pressure readings to the receiver module. The TPMS consists of the following components: • Receiver module • Four tire pressure monitoring sensors • Tire pressure monitoring telltale light There are two tire pressure monitoring systems available, a base system and a premium system. The base system does not specify how many tires are low or where they are located. The premium system does so. NOTE: The compact spare tire does not have a tire pressure monitoring sensor. A TPMS fault can occur with any of the following scenarios: • Signal interference due to electronic

devices or driving next to facilities emitting the same radio frequencies as the TPMS sensors. • Installing some form of aftermarket window tinting that affects radio wave signals. • Snow or ice around the wheels or wheel housings. • Using tire chains on the vehicle. • Using wheels/tires not equipped with TPMS sensors.
TIRE PRESSURE MONITOR WARNING INDICATORS The TPMS warning light will illuminate in the instrument cluster, an audible chime will be activated, and the “Check Tire Pressure” text message will display when one or more of the four active road tire pressures are low. Inflate each tire to the vehicle’s recommended cold placard pressure value. The system will automatically update and the tire pressure monitoring light will extinguish once the updated tire pressures have been received. The vehicle may need to be driven for up to 20 minutes above 15 mph (24 km/h) to receive this information. The TPMS warning light will flash on and off for 75 seconds and remain on solid when a system fault is detected, and the
“Tire Pressure Monitoring Unavailable” text message will display. If the ignition key is cycled, this sequence will repeat providing the system fault still exists. The TPMS warning light will turn off when the fault condition no longer exists. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warning limit, upon the next ignition key cycle, a chime will sound and the tire pressure monitoring telltale light will still turn ON due to the low tire. However, after driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the tire pressure monitoring telltale light will flash on and off for 75 seconds and then remain on solid.
TPMS RESET PROCEDURES The TPMS will automatically update and the tire pressure monitoring light will extinguish once correct tire pressures have been restored. The vehicle will need to be driven for up to 20 minutes above 15 mph (24 km/h) before the system receives this information.
TPMS SENSOR PROGRAMMING After a sensor has been replaced, the TPMS module automatically learns and stores the sensor IDs after the vehicle has been driven MTD December 2018
