The tire press monitoring device (TPMS) in 2008-2016 Chrysler city & nation vehicles monitors air push in the 4 road tires (excludes the spare). Press in the spare tires is not monitored. There space two tire press monitoring systems available, a basic system and a premium system. The base mechanism does not specify how countless tires room low or where they room located. The premium mechanism does so.

The basic TPMS consists of tire push monitoring sensors attached to each road wheel with the valve stem mounting hole, a main receiver module wireless ignition node (WIN), and an indicator lamp. The premium TPMS consists of tire pressure monitoring sensors attached to each roadway wheel v the valve stem mounting hole, a wireless control module, three wheel sensor transponders situated in 3 of the 4 wheel wells, an digital display, and also an indicator lamp.
Using one RF signal, every sensor transmits tire push data approximately once every minute. Every sensor’s (transmitter) broadcast is uniquely coded so the the sentry an essential remote entry module (SKREEM) deserve to monitor the state of every of the sensors on the four rotating roadway wheels. Upon detection the a warning or fault condition, the WIN will certainly send a request to the module the controls the indicator desk lamp (and the text display screen if equipped v the premium system) via the automobile bus mechanism to illuminate or flash the indicator lamp. Also, upon detection the a warning or error condition, the electronic display screen will send a inquiry to sound the “chime.”
The victory will keep all warning and fault conditions, placard press values and also low-pressure threshold worths (lamp ON and OFF) in storage that can be accessed through diagnostic communication. If new sensors are presented to the vehicle, the data stored for the sensor being replaced will it is in deleted. The victory will keep all wheel sensor IDs and also locations and also faults in storage that have the right to be accessed through diagnostic communication. All other data worths transmitted from each energetic wheel sensor (not the spare tire) shall be stored in the win memory.
After a sensor has been replaced, the WIN automatically learns and also stores the sensor IDs while driving continuously over 15 mph (24 km/h) for 10 minutes. The learning sequence will certainly initiate once the vehicle has been quit for an ext than 20 minutes. Under the following conditions, the system may not role properly:
• The areas, facilities or gadgets that use comparable radio tide frequencies are situated in the vicinity that the vehicle.
• A radio device of comparable frequency is used close to the vehicle.
• A the majority of snow or ice cream is grounding to the vehicle, especially roughly the wheels or wheel housings.
• The battery that the sensor has actually been depleted (approximate 10-year life span).
• A spare tires is installed.
• A tire without a tire push sensor is used.
• Wheels various other than manufacturer manufacturing facility wheels space used.
TIRE press MONITOR WARNING INDICATORS
If the TPMS detects the the tire press in any type of road tires is going low, the TPMS will repetitively illuminate an indicator lamp. In the premium TPMS, in addition to the chime and lamp, a graphic display of the push value(s) and also position of the low tire(s) will flash in the electronic vehicle information facility (EVIC). Once pressure in the doubt tire(s) raises over the low press (lamp) turn off threshold, and the TPMS module receive a valid infection from the sensor, the lamp will go out.
If a system fault is detected, a chime will sound, and also the TPMS indicator (telltale) lamp will certainly flash for 75 seconds, then stay on solid. For vehicles with the premium TPMS, a “CHECK TPM SYSTEM” post will appear in the EVIC, followed by a graphic display. Watch the proper manufacturer service information.
TPMS RESET PROCEDURES
NOTE: If a tire pressure sensor has been replaced, the tire push sensors must be retrained. When the tire press warning irradiate illuminates and also warning post appears, automatically check air press of every tires and readjust to the mentioned pressure. Drive the vehicle over 15 mph (24 km/h) for a few minutes. Certain warning indications go out.
TIRE pressure SENSOR RETRAINING
NOTE: The car must be stationary for much more than 20 minute in order to initiate the discovering sequence.
Automatic sensor training
The SKREEM instantly learns and also stores the sensor’s ID if driving after ~ a sensor has actually been replaced. Over there is no formal retraining procedure necessary. Drive the car for a minimum the 10 come 20 minutes while keeping a consistent speed above 15 mph (24 km/h). Throughout this time, the mechanism will find out the brand-new sensor i would code and will clear any kind of DTCs automatically. If a sensor cannot be trained, watch the suitable manufacturer service information.
Scan device sensor training
NOTE: A brand-new sensor i would can additionally be programmed directly into the success or TPMS module by using an RKE-TPM Analyzer in conjunction with a scan tool. Using a TPM-RKE Analyzer have the right to take as much as a minute to force a transmission from a sensor. As soon as the brand-new sensor ID has actually been programmed, the automobile will have to be driven above 15 mph (24 km/h) until the fault is no longer energetic (lamp extinguishes) and also the display screen is updated (10 to 20 minutes).
Scan each TPMS sensor at each road wheel, and also then keep each sensor id in the correct location (left front, left rear, ideal front, and also right rear).
Connect the TPM-RKE Analyzer device to the scan tool. Climate follow the programming procedures outlined in the diagnostic scan tool for “Program Tire pressure Sensor id w/ TPM Tool.”
CAUTION: The tire have to be demounted indigenous the wheel making use of the tire changer manufacturer’s instructions. Use the following information to avoid damages during the demounting/mounting procedures.
CAUTION: The TPMS has been optimized because that the original devices tires and wheels. TPMS pressures have been developed for the tire size equipped top top the vehicle. Undesirable mechanism operation or sensor damages may an outcome when making use of replacement tools that is no of the same size, type, or style. Aftermarket wheels can reason sensor damage.
Do not usage aftermarket tire sealants or balance beads if your car is equipped through TPMS, as damages to the sensors might result. NOTE: If a tire press sensor has actually been replaced, the tire pressure sensors should be retrained. View “TPMS RESET PROCEDURES.”
NOTE: If the tires require leak-testing, a water test may be offered to examine for a leak about the sensor as lengthy as any kind of water in ~ the valve core is removed when the procedure is completed. Water deserve to be expelled indigenous the core area by advertise in ~ above the main point for numerous seconds, enabling escaping wait to journey out any moisture. Re-inflate the tire as necessary. Download the initial valve stem cap.
NOTE: Wheels and tires are match-mounted in ~ the factory. Before demounting a tires from that is wheel, a reference mark should be placed on the tire at the valve stem location, come ensure the it is remounted in the initial position top top the wheel. Because that match-mounting procedures, refer to the suitable manufacturer company information.
NOTE: Tire pressure may rise from 2 come 6 psi (14 come 41 kPa) during normal control conditions. Do NOT reduce this regular pressure build up.
TIRE push SENSOR
IMPORTANT: This auto uses the 433 MHz TPMS sensor. Although 315 MHz and also 433 MHz sensors are similar in size and shape, they space not interchangeable. Constantly make certain the exactly sensor is gift used.
An RKE-TPM Analyzer have the right to be provided to recognize the sensors frequency without having to demount the tire.
CAUTION: The cap provided on this valve stem has an O-ring seal to protect against contamination and also moisture indigenous entering the valve stem. Retain this valve stem cap for reuse. Do not substitute a regular valve stem lid in the place.
CAUTION: do not attempt to install a tire press sensor in one aftermarket wheel. Use tire push sensors in initial style manufacturing facility wheels only. If aftermarket wheels space installed, and therefore carry out not save tire press sensors, the mechanism will not duty properly and the driver will certainly be continuously educated of a device malfunction.
CAUTION: after ~ inspecting or adjusting the tires pressure always reinstall the valve stem cap. This will stop moisture and also dirt indigenous entering the valve stem, which can damage the tire push sensor.
CAUTION: The valve stem offered on this vehicle is made of aluminum and the main point is nickel plated brass. The initial valve stem core need to be reinstalled and also not substituted through a valve stem main point made the a various material. This is forced to protect against corrosion in the valve stem brought about by the different metals.
CAUTION: any kind of time a sensor is come be mounted in a wheel, it is important to download a new sensor-to-wheel seal, metal washer and also valve stem nut, come ensure airtight sealing (see number 1). CAUTION: carry out NOT reuse the sensor-to-wheel grommet. Constantly use a brand-new grommet as soon as installing a push sensor and also properly talk the sensor nut.
1) remove the tire and wheel assembly native the vehicle.
2) Demount the tires from the wheel complying with the tire changer manufacturer’s instructions if paying unique attention to the following to avoid damaging the press sensor:
• when breaking the tires bead loosened from the wheel rim, stop using the bead breaker in the area of the sensor. That consists of both front and also rear beads of the tire (see Figure. 3).
• when preparing to demount the tires from the wheel, carefully insert the mounting/demounting device at the valve stem +/- 10 degrees, then continue to demount the tires from the wheel. Usage this process on both the upper and also lower tires beads.
3) making use of a thin-walled socket, eliminate the one-of-a-kind nut retaining sensor to the wheel. When removing the nut, host pressure versus the behind of the steel valve stem to store the valve stem from advertise rearward, which can damage the antenna strap (see Figure. 2).
4) remove the sensor native the wheel (see figure 4).
NOTE: before reinstalling an currently tire pressure sensor, replace the seal and also metal washer at the basic of the valve stem come ensure proper sealing (see number 1).
1) Wipe the area clean roughly the sensor/valve stem mounting hole in the wheel. Make certain the surface of the wheel is not damaged. CAUTION: To protect against damaging the sensor antenna strap, organize pressure versus the rear of the steel valve stem if the sensor is placed through the wheel mounting hole and also the nut is mounted (see figures 2 and also 4).
2) Insert the sensor through the wheel as displayed keeping pressure versus the rear of the metal valve stem. The potted next of the sensor is to be positioned towards the wheel.
Do no attempt to mountain the sensor otherwise, or damages may occur. Download the sensor nut (with pressed-in washer) by hand (see numbers 4 and 5).
NOTE: prior to tightening the sensor nut, push downward top top the sensor housing in an effort to do it flush v the internal contour the the wheel.
3) using a thin-walled socket, download the sensor nut. When holding the sensor in position, tighten the sensor seed to 40 in.-lbs. (4.5 N.m).
CAUTION: Over-torquing the sensor seed by as tiny as 106 in.-lbs. (12 N.m) may an outcome in sensor separation indigenous the valve stem.
Under this condition, the sensor may still function; however, the problem should be repair immediately.
4) mountain the tire on the wheel complying with the tires changer manufacturer’s instructions, paying unique attention come the complying with to stop damaging tire pressure sensor:
Rotating wheel tires changers
Once the wheel is placed to the changer, position the sensor valve stem approximately 210 levels from the head the the changer in a clockwise direction prior to rotating the wheel (also in a clockwise direction) to mount the tire. Use this procedure on both the upper and also lower tire beads (see figure 6).
Rotating tool tire changers
Position the wheel top top the changer so that the sensor valve stem is about 210 levels from the head of the changer in a clockwise direction indigenous the mounting end of the tool (see number 7). Make certain the sensor is clean of the reduced bead breaker area to prevent damaging the sensor as soon as the breaker rises. Rotate the tool in a counterclockwise direction to mount the tire. Use this procedure top top both the upper and also lower tires beads.
5) change air press to specification. Make certain the original style valve stem lid is securely set up to store moisture the end of the sensor. Install the wheel and also tire assembly ~ above the vehicle.
