The base TPMS consists of tire pressure monitoring sensors attached come each road wheel v the valve stem mounting hole, a central receiver module wireless ignition node (WIN), and an indicator lamp. The premium TPMS consists of tire push monitoring sensors attached come each road wheel with the valve stem mounting hole, a wireless manage module, 3 wheel sensor transponders situated in 3 of the four wheel wells, an digital display, and also an indicator lamp.

Using an RF signal, each sensor transmits tire pressure data approximately once every minute. Every sensor’s (transmitter) broadcast is unique coded so that the sentry an essential remote entry module (SKREEM) deserve to monitor the state of every of the sensors top top the 4 rotating road wheels. Upon detection that a warning or fault condition, the WIN will send a request to the module the controls the indicator desk lamp (and the text screen if equipped with the premium system) via the auto bus device to illuminate or speed the indicator lamp. Also, top top detection that a warning or fault condition, the electronic display screen will send a request to sound the “chime.”

The success will store all warning and also fault conditions, placard press values and also low-pressure threshold values (lamp ON and also OFF) in memory that deserve to be accessed through diagnostic communication. If brand-new sensors are introduced to the vehicle, the data stored because that the sensor being replaced will be deleted. The success will store all wheel sensor IDs and locations and also faults in storage that have the right to be accessed v diagnostic communication. All various other data values transmitted native each active wheel sensor (not the spare tire) shall it is in stored in the win memory.

After a sensor has actually been replaced, the WIN automatically learns and stores the sensor IDs if driving continuously above 15 mph (24 km/h) because that 10 minutes. The finding out sequence will certainly initiate once the car has been stopped for more than 20 minutes. Under the following conditions, the system may not role properly:

• The areas, framework or gadgets that use similar radio wave frequencies are situated in the vicinity the the vehicle.

• A radio an equipment of similar frequency is used near the vehicle.

• A many snow or ice cream is grounding to the vehicle, especially about the wheels or wheel housings.

• The battery of the sensor has been depleted (approximate 10-year life span).

• A spare tires is installed.

• A tire without a tire push sensor is used.

• Wheels other than manufacturer factory wheels are used.

TIRE press MONITOR WARNING INDICATORS

If the TPMS detects that the tire push in any road tire is walk low, the TPMS will repetitively illuminate one indicator lamp. In the premium TPMS, in addition to the chime and also lamp, a graphic display of the press value(s) and position of the low tire(s) will flash in the electronic car information center (EVIC). Once pressure in the doubt tire(s) raises over the low push (lamp) turn off threshold, and the TPMS module obtain a valid infection from the sensor, the lamp will certainly go out.

If a mechanism fault is detected, a chime will sound, and also the TPMS indicator (telltale) lamp will certainly flash because that 75 seconds, then stay on solid. For vehicles with the premium TPMS, a “CHECK TPM SYSTEM” article will appear in the EVIC, complied with by a graphic display. Watch the suitable manufacturer organization information.

TPMS RESET PROCEDURES

NOTE: If a tire push sensor has been replaced, the tire press sensors have to be retrained. Once the tire pressure warning light illuminates and warning post appears, immediately check air push of every tires and adjust to the specified pressure. Journey the vehicle over 15 mph (24 km/h) for a few minutes. Ensure warning indicators go out.

TIRE push SENSOR RETRAINING

NOTE: The auto must be stationary for an ext than 20 minute in order come initiate the learning sequence.

Automatic sensor training

The SKREEM automatically learns and also stores the sensor’s ID when driving ~ a sensor has been replaced. There is no official retraining procedure necessary. Drive the car for a minimum that 10 to 20 minute while keeping a continuous speed over 15 mph (24 km/h). Throughout this time, the system will learn the brand-new sensor i would code and also will clear any DTCs automatically. If a sensor can not be trained, check out the appropriate manufacturer business information.

Scan tool sensor training

NOTE: A brand-new sensor identifier can additionally be programmed directly into the success or TPMS module by using an RKE-TPM Analyzer in conjunction through a scan tool. Making use of a TPM-RKE Analyzer have the right to take approximately a minute to force a transmission from a sensor. As soon as the new sensor ID has actually been programmed, the car will have to be driven over 15 mph (24 km/h) till the fault is no longer energetic (lamp extinguishes) and the display is to update (10 come 20 minutes).

Scan every TPMS sensor in ~ each road wheel, and then save each sensor identifier in the correct location (left front, left rear, right front, and right rear).

Connect the TPM-RKE Analyzer tool to the scan tool. Climate follow the programming actions outlined in the diagnostic scan tool for “Program Tire push Sensor identifier w/ TPM Tool.”

DEMOUNTING/MOUNTING PROCEDURES

CAUTION: The tire have to be demounted from the wheel making use of the tire changer manufacturer’s instructions. Usage the complying with information come avoid damage during the demounting/mounting procedures.

CAUTION: The TPMS has been optimized for the original equipment tires and also wheels. TPMS pressures have actually been created for the tire size equipped top top the vehicle. Undesirable system operation or sensor damages may result when using replacement equipment that is not of the exact same size, type, or style. Aftermarket wheel can reason sensor damage.

Do not usage aftermarket tires sealants or balance beads if your vehicle is equipped through TPMS, as damages to the sensors might result. NOTE: If a tire push sensor has actually been replaced, the tire push sensors should be retrained. Watch “TPMS RESET PROCEDURES.”

NOTE: If the tires call for leak-testing, a water test might be supplied to check for a leak around the sensor as long as any type of water at the valve main point is removed as soon as the procedure is completed. Water deserve to be expelled from the core area by advertise in on the main point for numerous seconds, enabling escaping air to drive out any moisture. Re-inflate the tire as necessary. Download the initial valve stem cap.

NOTE: Wheels and tires are match-mounted at the factory. Prior to demounting a tire from that wheel, a reference note should be inserted on the tire at the valve stem location, to ensure the it is remounted in the original position on the wheel. For match-mounting procedures, refer to the proper manufacturer company information.

NOTE: Tire pressure may rise from 2 come 6 psi (14 to 41 kPa) during normal control conditions. Do NOT mitigate this common pressure build up.

TIRE pressure SENSOR

IMPORTANT: This vehicle uses the 433 MHz TPMS sensor. Although 315 MHz and 433 MHz sensors are similar in size and also shape, they are not interchangeable. Always make certain the correct sensor is gift used.

An RKE-TPM Analyzer have the right to be supplied to identify the sensors frequency without having actually to demount the tire.

CAUTION: The cap offered on this valve stem consists of an O-ring seal to prevent contamination and moisture from entering the valve stem. Retain this valve stem cap for reuse. Carry out not instead of a continuous valve stem lid in its place.

CAUTION: perform not attempt to install a tire pressure sensor in an aftermarket wheel. Usage tire push sensors in original style manufacturing facility wheels only. If aftermarket wheels space installed, and therefore perform not save tire push sensors, the system will not duty properly and also the driver will be continuously informed of a mechanism malfunction.

CAUTION: ~ inspecting or adjusting the tire pressure constantly reinstall the valve stem cap. This will avoid moisture and also dirt native entering the valve stem, which might damage the tire pressure sensor.

CAUTION: The valve stem provided on this automobile is do of aluminum and the core is nickel plated brass. The original valve stem core have to be reinstalled and not substituted v a valve stem main point made the a various material. This is required to stop corrosion in the valve stem brought about by the various metals.

CAUTION: any time a sensor is come be set up in a wheel, the is necessary to download a new sensor-to-wheel seal, metal washer and valve stem nut, to ensure airtight sealing (see figure 1). CAUTION: do NOT reuse the sensor-to-wheel grommet. Constantly use a new grommet as soon as installing a push sensor and properly speak the sensor nut.

Removal

1) remove the tire and also wheel assembly native the vehicle.

2) Demount the tire from the wheel adhering to the tires changer manufacturer’s instructions while paying one-of-a-kind attention to the following to stop damaging the pressure sensor:

• when breaking the tire bead loose from the wheel rim, protect against using the bead breaker in the area the the sensor. That contains both front and also rear beads that the tire (see Figure. 3).

• when preparing come demount the tire from the wheel, carefully insert the mounting/demounting device at the valve stem +/- 10 degrees, then continue to demount the tire from the wheel. Usage this process on both the upper and also lower tire beads.

3) making use of a thin-walled socket, remove the unique nut retaining sensor to the wheel. While removing the nut, hold pressure against the behind of the metal valve stem to store the valve stem from advertise rearward, which might damage the antenna strap (see Figure. 2).

4) remove the sensor indigenous the wheel (see figure 4).

Installation

NOTE: prior to reinstalling an present tire pressure sensor, replace the seal and also metal washer at the base of the valve stem to ensure ideal sealing (see figure 1).

1) Wipe the area clean about the sensor/valve stem mounting feet in the wheel. Make certain the surface of the wheel is not damaged. CAUTION: To protect against damaging the sensor antenna strap, hold pressure versus the behind of the steel valve stem while the sensor is placed through the wheel mounting hole and the nut is installed (see numbers 2 and 4).

2) Insert the sensor through the wheel as displayed keeping pressure against the behind of the steel valve stem. The potted next of the sensor is to be positioned towards the wheel.

Do no attempt to mount the sensor otherwise, or damage 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 ~ above the sensor real estate in an effort to do it flush v the internal contour of the wheel.

3) utilizing a thin-walled socket, download the sensor nut. While holding the sensor in position, tighten the sensor nut to 40 in.-lbs. (4.5 N.m).

CAUTION: Over-torquing the sensor nut by as little as 106 in.-lbs. (12 N.m) may an outcome in sensor separation indigenous the valve stem.

Under this condition, the sensor might still function; however, the condition should be corrected immediately.

4) mountain the tires on the wheel complying with the tire changer manufacturer’s instructions, paying one-of-a-kind attention come the following to stop damaging tire push sensor:

Rotating wheel tire changers

Once the wheel is an installed to the changer, place the sensor valve stem about 210 degrees from the head the the changer in a clockwise direction prior to rotating the wheel (also in a clockwise direction) to mountain the tire. Usage this procedure on both the upper and lower tire beads (see figure 6).

Rotating tool tire changers

Position the wheel top top the changer so that the sensor valve stem is approximately 210 levels from the head of the changer in a clockwise direction from the mounting end of the device (see figure 7). Make certain the sensor is clean of the lower bead breaker area to protect against damaging the sensor once the breaker rises. Revolve the tool in a counterclockwise direction to mountain the tire. Use this procedure ~ above both the upper and also lower tire beads.

5) change air push to specification. Make certain the original format valve stem lid is securely mounted to store moisture out of the sensor. Install the wheel and also tire assembly ~ above the vehicle.
