Safety Precautions

Note. Do not clean aluminum wheels with steel wool, abrasive-type cleaners or strong detergents or damage to the wheel finish may occur. Use Wheel and Tire Cleaner ZC-27-A or -B or equivalent.

Factory-installed tires and wheels are designed to operate satisfactorily with loads up to and including full-rated load capacity when inflated to recommended inflation pressures.

Correct tire pressure and driving techniques have an important influence on tire life. Heavy cornering, excessively rapid acceleration and unnecessary sharp braking increase tire wear.

To equalize tire wear, the tires should be rotated at recommended intervals.

Tire Pressure Monitoring System (TPMS)

Note. The Smart Junction Box (SJB) is also identified as the Generic Electronic Module (GEM).

The Tire Pressure Monitoring System (TPMS) includes

1. the SJB, TPMS functionality is integrated within the SJB.
2. four tire pressure sensors.
3. four tire pressure sensor cradles.
4. four tire pressure sensor straps.
5. an instrument cluster indicator.
6. a message center (if equipped).

Tire Pressure Monitoring System (TPMS) Module

The SJB contains the TPMS functionality. Refer to Tire Pressure Monitoring System in Diagnosis and Testing for TPMS fault diagnosis and repair.

The SJB compares the information of each tire pressure sensor transmission against a pressure limit. If the SJB determines that the tire pressure has fallen below the low limit, the SJB communicates this to the instrument cluster on the vehicle communication bus.

Tire Pressure Monitoring System (TPMS) Pressure Sensor

The SJB monitors the air pressure in the 4 road tires with tire pressure sensors. The sensors transmit radio frequency signals to the SJB approximately every 60 seconds when the vehicle speed exceeds 32 km/h (20 mph).

The tire pressure sensors are battery operated and are mounted to metal brackets (called cradles) on the wheels inside the tires. The sensors are mounted 180 degrees from the valve stem.

The tire pressure sensor can be serviced separately from the cradle and the strap.

Tire Pressure Monitoring System (TPMS) Pressure Sensor Cradle

The tire pressure sensor cradles are mounted to the wheels with metal straps and have an adhesive strip to aid in their retention to the wheel.

The sensor cradle is available with the strap in a kit. To service the sensor cradle, the strap must be removed and discarded.

Tire Pressure Monitoring System (TPMS) Pressure Sensor Strap

The sensor strap keeps the sensor and the cradle retained to the wheel. A factory-installed strap is joined together with a one-time-use buckle and a dealer-installed strap is joined together with a worm gear (similar to a radiator hose clamp). Both straps should be discarded after removal and should not be reused.

The cradle and strap are available as a strap kit. There are several different strap kits available based on wheel diameter.

Instrument Cluster and Message Center

The instrument cluster illuminates the TPMS indicator when it receives a message from the SJB to do so and displays the appropriate message(s) in the message center (if equipped).

The instrument cluster and message center are diagnosed and serviced in their own respective workshop manual articles. Refer to the appropriate Instrumentation and Warning Systems article for the procedure.

Inspection and Verification

Be sure to follow all warnings when carrying out Inspection and Verification.

Verify the customer concern by carrying out a road test on a smooth road. If any vibrations are apparent, go to NVH .

To maximize tire performance, inspect for signs of incorrect inflation and uneven wear, which may indicate a need for balancing, rotation or front suspension alignment.

Correct tire pressure and driving techniques have an important influence on tire life. Heavy cornering, excessively rapid acceleration and unnecessary sharp braking increase tire wear.

Replacement tires must follow the recommended

1. tire sizes.
2. speed rating.
3. load range.
4. tire construction type.

The use of any other tire/wheel size, load range or type can seriously affect

1. ride.
2. handling.
3. speedometer/odometer calibration.
4. vehicle ground clearance.
5. tire clearance between the body and chassis.
6. wheel bearing life.
7. braking performance.

New wheels need to be installed when the vehicle wheels

1. are bent.
2. are cracked.
3. are dented.
4. are heavily corroded.
5. are leaking.
6. have elongated wheel hub bolt holes.
7. have excessive lateral or radial runout.

It is mandatory to use only the tire sizes recommended on the tire label located on the driver door or door pillar attached to the vehicle. Larger or smaller tires can damage the vehicle, affect durability and require changing the speedometer calibration. Make sure wheel size and offsets match those recommended for the tire in use.

1. Inspect the tires for signs of uneven wear. Refer to the following descriptions to identify the type of wear and Go to «Tire Wear»(/ford/taurus-x/i-2007-2009/remont/wheel-tire-system/#wheels-tires) for the appropriate repair action to be carried out.
2. Check the tires for: cuts. stone bruises. abrasions. blisters. embedded objects.
3. Tread wear indicators are molded into the bottom of the tread grooves. Install a new tire when the indicator bands become less than 1.58 mm (0.062 in).

Tire Wear

Tire wear is commonly defined as a loss of tread depth. Tire tread wear occurs due to friction with the contact surface (road/pavement). The tread should wear down uniformly all the way around the circumference of the tire and all the way across the tread face. When this does not occur, the tire may have abnormal/incorrect wear.

Normal Tire Wear

Normal tire wear is identified as even wear around and across the tread. Because there are many factors (driving style, road surfaces, type of vehicle, type of tire) that can affect tire wear, there is no absolute mileage expectation for a normal wear condition. A tire is considered worn-out when the tread has worn to the level of the tread-wear indicators.

Abnormal/Incorrect Tire Wear

Abnormal/incorrect tire wear is identified as tire wear that is not even around or across the tread and that creates performance-related issues.

Abnormal/incorrect wear can be caused by numerous factors, some of which include driving style (aggressive, passive), climate (hot, cold), road conditions, vehicle loading and maintenance (correct tire pressure, rotation intervals and balance). It is important to determine the root cause of wear on a vehicle before carrying out repair. Tires exhibiting abnormal/incorrect tire wear may still be serviceable provided that the minimum tread depth is greater than 1.58 mm (0.062 in) and the tire is not causing a vehicle performance (noise/vibration) concern.

Some abnormal/incorrect wear patterns look the same all the way around the tread of the tire, other wear patterns are not consistent and can occur in various spots on the tread area. The underlying causes of the 6 wear categories are different. Refer to the following descriptions to identify the type of wear and Go to Tire Wear for the appropriate repair action to be carried out.

Inner Edge/Shoulder Wear

Inner edge (or shoulder) wear occurs on the inside edge of the tire and is usually caused by excessive toe-out and/or excessive negative camber. If the tread depth of the outer shoulder is at least 50% greater than the tread depth of the inner shoulder, the tire is experiencing inner edge/shoulder wear. To determine whether tires have this type of wear, visually inspect the tires. In some instances, it may be necessary to measure the tread depth of each rib and compare it to that of the shoulder.

Note. RF tire shown, others similar.

Scheme 1

Outer Edge/Shoulder Wear

Outer edge (or shoulder) wear occurs on the outside edge of the tire and is usually caused by excessive toe-in and/or excessive positive camber. If the tread depth of the inner shoulder is at least 50% greater than the tread depth of the outer shoulder, the tire is experiencing outer edge/shoulder wear. To determine whether tires have this type of wear, visually inspect the tires. In some instances, it may be necessary to measure the tread depth of each rib and compare it to that of the shoulder.

Note. RF tire shown, others similar.

Scheme 2

Heel/Toe Wear

Heel/toe wear (also known as feathering) occurs along the outside or inside edge/shoulder of the tire. To determine whether tires have this type of wear, visually inspect the tires in both the inside and outside shoulder ribs. In some instances, it may be necessary to measure the difference in tread depth of leading versus trailing edge of each lug in the inside and outside shoulder rib.

Scheme 3

Diagonal Wear

Diagonal wear occurs diagonally across the tread area and around the circumference of the tire. To determine whether tires have this type of wear, visually inspect the tires to determine if the wear pattern runs diagonally across the tread and around the circumference of the tire. In some instances, the difference in tread depth along the diagonal wear pattern may need to be measured.

Component Tests

Some vehicles may exhibit a wheel and tire vibration caused by excessive runout. Runout measurements of the wheel and tire assembly can be taken both on and off the vehicle. Runout measurements can be taken both radially and laterally using a runout gauge. The runout gauge is a delicate, precision instrument and should be handled as such. The runout gauge should be mounted on a heavy solid base to eliminate gauge movement when measuring runouts. The measurements are taken using a runout gauge, which defines total runout in 64th or thousandths of an inch (depending on the brand of gauge used) and locates the high and low points of the runout.

Radial Runout

Radial runout is the egg-shaped deviation from a perfect circle and is measured perpendicular on a circumference. On a wheel and tire assembly, this usually means measuring the center tire tread rib, although other tread ribs can be measured as well. The center rib is usually a solid rib, easy to measure and normally indicative of the condition of the tire as a whole. It is important to keep in mind that any rib with excessive runout can cause a concern. Total runout is the reading from the gauge. The high spot is the location of maximum runout.

Scheme 5

Note. Warm up the tires prior to taking any measurements, this will eliminate slight flat spotting. This is done during a road test.

1. Make sure that the tire pressures are set to the correct pressure as indicated on the vehicle label.
2. With the vehicle in NEUTRAL, position it on a hoist. Refer to «JACKING AND LIFTING»(/ford/taurus-x/i-2007-2009/remont/hoistjack/#jacking-and-lifting) article.
3. Make sure that all 4 positions can be measured. If measurements are to be taken with the wheel and tire assembly off the vehicle, mount each assembly on a suitable dynamic balancing machine.
4. For future reference of the original wheel and tire assembly's position on the wheel hub, index-mark the wheel and a wheel stud.
5. Position the runout gauge to take a radial measurement. Rotate the wheel and tire assembly (or wheel) to locate the low spot. Adjust the runout gauge to read 0. Rotate the wheel and tire assembly (or wheel) one complete revolution to make sure that the low spot has been found and that the runout gauge dial returns to a 0 reading.
6. While slowly and constantly rotating the wheel and tire assembly (or wheel), measure the radial runout. Note the variance (runout) from 0 on the dial of the gauge. If the runout reading of a wheel and tire assembly is not within 1.27 mm (0.050 in), locate and mark the high spot and proceed to Match Mounting Step 1 to correct the concern. If the runout reading of a wheel is not within 1.27 mm (0.050 in), install a new wheel.

Lateral Runout

Lateral runout is a sideways variation causing a twist or wobble and is measured on a side surface. On the wheel and tire assembly, the lateral runout measurement should be taken as close to the tread shoulder as possible. Total runout is the reading from the gauge.

Scheme 6

1. Position the runout gauge to take a lateral measurement. Rotate the wheel and tire assembly (or wheel) to locate the low spot. Adjust the runout gauge to read 0. Rotate the wheel and tire assembly (or wheel) one complete revolution to make sure that the low spot has been found and that the dial returns to a 0 reading.
2. While slowly and constantly rotating the wheel and tire assembly (or wheel), measure the lateral runout. Note the variance (runout) from 0 on the dial of the gauge. If the runout reading of a wheel and tire assembly is not within 1.27 mm (0.050 in), locate and mark the high spot and proceed to Match Mounting Step 1 to correct the concern. If the runout reading of a wheel is not within 1.27 mm (0.050 in), install a new wheel.

Match Mounting

Match mounting is a technique used to reduce radial and lateral runouts on wheel and tire assemblies. Excessive runout is a source of ride quality complaints and match mounting can be used to minimize the runout. Match mounting can be accomplished by changing the position of the tire on the wheel or by changing the position of the wheel and tire assembly on the hub.

Principles of Operation

Note. The Smart Junction Box (SJB) is also referred to as the Generic Electronic Module (GEM).

The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all 4 road tires. The wheel-mounted tire pressure sensors transmit via radio frequency signals, to the SJB. TPMS functionality is integral to the SJB. These transmissions are sent approximately every 60 seconds when the vehicle speed exceeds 32 km/h (20 mph). The TPMS function compares each tire pressure sensor transmission against a low-pressure limit. If it has been determined that the tire pressure has fallen below this limit, the SJB communicates this on the vehicle communication bus to the instrument cluster. The instrument cluster then illuminates the TPMS indicator and displays the appropriate message(s) in the message center (if equipped).

For vehicles with different front and rear tire pressures (such as the E-Series and certain F-Series), the tire pressures must be adjusted and the tire pressure sensors must be trained following a tire rotation. Failure to train the sensors will cause the TPMS indicator to illuminate.

For vehicles with the same tire pressures for front and rear tires, tire rotation will not affect the system.

Ambient Temperature Change and Tire Pressure

Tire pressures fluctuate with temperature changes. For this reason, tire pressure must be set to specification when tires are at outdoor ambient temperatures. If the vehicle is allowed to warm up to shop temperatures, and the outside temperature is less than shop temperature, the tire inflation pressure must be adjusted accordingly.

If the tires are inflated to specification at shop temperatures, and the vehicle is moved outdoors when the outdoor ambient temperature is significantly lower, the tire pressure may drop enough to be detected by the TPMS and activate the TPMS warning lamp.

As the ambient temperature decreases by 6°C (10°F), tire pressure decreases 7 kPa (1 psi). Adjust the tire pressure by 7 kPa (1 psi) for each 6°C (10°F) ambient temperature drop as necessary to keep the tire at the specified Vehicle Certification (VC) label pressure. Refer to the following tables to adjust the tire pressure indoors for colder outside temperatures.

Scheme 8

Tire Pressure Monitoring System (TPMS) Indicator and Message Center Messages

The TPMS indicator and vehicle message center (if equipped) sometimes displays faults that cannot be resolved by the customer. Treat these messages as TPMS faults that must be serviced.

Tire Pressure Monitoring System (TPMS) Indicator Illuminates Continuously

Note. If the spare tire is in use, the damaged road tire must be repaired and installed on the vehicle to restore complete TPMS functionality before carrying out any diagnosis.

Note. For vehicles with different front and rear tire pressures (such as E-Series and certain F-Series), the tire pressure sensors must be trained following a tire rotation. Failure to train the sensors will result in a false low tire pressure event, which will cause the TPMS indicator to illuminate.

1. The TPMS indicator remains on continuously for the following condition: Low Tire Pressure - The TPMS indicator is illuminated solid and the message center displays LOW TIRE PRESSURE (if equipped). This is displayed when any of the tire pressures are low. When this condition exists, the tire pressure must be adjusted to the recommended cold pressure as indicated on the VC label.
2. If the vehicle has been stationary for more than 30 minutes, carry out the «Tire Pressure Monitoring System (TPMS) Sensor Activation»(/ford/taurus-x/i-2007-2009/remont/wheel-tire-system/#wheels-tires__tire-pressure-monitoring-system-tpms-sensor) procedure.

Tire Pressure Monitoring System (TPMS) Indicator Flashes

The TPMS indicator flashes for 70 seconds, then remains ON solid when the ignition switch is turned to the ON position, for the following conditions

1. Tire Pressure Sensor Fault - If equipped, the message center will display TIRE PRESSURE SENSOR FAULT when a tire pressure sensor is malfunctioning. Go to «Symptom Chart»(/ford/taurus-x/i-2007-2009/remont/wheel-tire-system/#wheels-tires) .
2. No communication with the SJB (TPMS is integral to the SJB) - The TPMS indicator is illuminated when the instrument cluster has not received any signals from the SJB for more than 5 seconds. If equipped, the message center displays TIRE PRESSURE MONITOR FAULT. Go to «Symptom Chart»(/ford/taurus-x/i-2007-2009/remont/wheel-tire-system/#wheels-tires) .
3. Tire Pressure Monitor Fault - If equipped, the message center will display TIRE PRESSURE MONITOR FAULT when the tire pressure monitoring system is malfunctioning or communication with the instrument cluster has been lost. Go to «Symptom Chart»(/ford/taurus-x/i-2007-2009/remont/wheel-tire-system/#wheels-tires) .

1. Verify the customer concern by inspecting the vehicle and observing the message center (if equipped) and the TPMS indicator.
2. Inspect to determine if one of the following mechanical or electrical concerns apply: VISUAL INSPECTION CHART Mechanical Electrical Low tire pressure Tire Pressure Monitoring System (TPMS) sensor damaged or missing Spare tire installed as a road wheel Incorrect TPMS sensor installed TPMS sensor installed incorrectly Sensors not trained after a tire rotation on vehicles with different front and rear tire pressures Non-OEM wheels installed (aftermarket rims) Non-OEM equipped run-flat tires installed Other non-OEM modifications (roll cages, service barriers, part racks, ladder racks) Wiring, terminals or connectors Smart Junction Box (SJB) damaged Aftermarket electronic accessories
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
5. If the scan tool does not communicate with the VCM: check the VCM connection to the vehicle. check the scan tool connection to the VCM. refer to «MODULE COMMUNICATIONS NETWORK»(/ford/taurus-x/i-2007-2009/remont/communication-devices/#module-communications-network-system) article, No Power To The Scan Tool, to diagnose no power to the scan tool.
6. If the scan tool does not communicate with the vehicle: verify the ignition key is in the ON position. verify the scan tool operation with a known good vehicle. refer to «MODULE COMMUNICATIONS NETWORK»(/ford/taurus-x/i-2007-2009/remont/communication-devices/#module-communications-network-system) article to diagnose no response from the PCM.
7. Carry out the network test. If the scan tool responds with no communication for one or more modules, refer to «MODULE COMMUNICATIONS NETWORK»(/ford/taurus-x/i-2007-2009/remont/communication-devices/#module-communications-network-system) article. If the network test passes, retrieve and record continuous memory DTCs.
8. Clear the continuous DTCs and carry out the self test diagnostics for the SJB (the TPMS is part of the SJB).
9. If the DTCs retrieved are related to the concern, go to the «TIRE PRESSURE MONITORING SYSTEM (TPMS) DTC TABLE»(/ford/taurus-x/i-2007-2009/remont/wheel-tire-system/#wheels-tires) . For all other DTCs, refer to the Master DTC Table in «MULTIFUNCTION ELECTRONIC MODULES»(/ford/taurus-x/i-2007-2009/remont/communication-devices/#multifunction-electronic-modules-system) article.
10. If no DTCs related to the concern are retrieved, go to «Symptom Chart»(/ford/taurus-x/i-2007-2009/remont/wheel-tire-system/#wheels-tires) .

TIRE PRESSURE MONITORING SYSTEM (TPMS) DTC TABLE

Symptom Chart

Note. For vehicles with different front and rear tire pressure (such as E-Series and certain F-Series), the tire pressures must be adjusted and the tire pressure sensors must be trained following a tire rotation. Failure to train the sensors will result in a false low tire pressure event, which will cause the Tire Pressure Monitoring System (TPMS) indicator to illuminate. For vehicles with the same tire pressure for front and rear tires, tire rotation will not affect the system. Failure of a TPMS component may not cause the message center to display a fault message or a DTC to be stored. The Symptom Chart is a starting point to begin diagnosis of these concerns.

Normal Operation

The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all 4 road tires. The wheel-mounted tire pressure sensors transmit via radio frequency signals, to the Smart Junction Box (SJB). TPMS functionality is integral to the SJB. These transmissions are sent approximately every 60 seconds when the vehicle speed exceeds 32 km/h (20 mph). The TPMS function (integral to the SJB) compares each tire pressure sensor transmission against a low-pressure limit. If it has been determined that the tire pressure has fallen below this limit, the SJB communicates this on the vehicle communication bus to the instrument cluster. The instrument cluster then illuminates the TPMS indicator and displays the appropriate message(s) in the message center (if equipped).

This symptom can also be caused by a spare tire currently being used in place of a road tire. Make sure that the spare tire is not currently in use. On vehicles with different front and rear tire pressures, if the sensors are not trained following a tire rotation, this symptom will also be present. Advise the customer that on vehicles with different front and rear tire pressures, the sensors must be trained as directed in the Owner's Literature.

This pinpoint test is intended to diagnose the following

1. Low air pressure in tire(s)
2. Tire pressure sensor(s)

Tire Pressure Monitoring System (TPMS) Sensor Training

Special Tools Illustration Tool Name Tool Number Activation Tool, Tire Pressure Monitor 204-363 Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool

Note. If the vehicle has been stationary for more than 30 minutes, the sensors will go into a "sleep mode" to conserve battery power. It will be necessary to wake them up so they will transmit the latest tire pressure information to the Smart Junction Box (SJB). For additional information, refer to Tire Pressure Monitoring System (TPMS) Sensor Activation .

Note. The tire pressure sensor training procedure must be done on a single vehicle, in an area without radio frequency noise and at least 1 m (3 ft) away from other vehicles equipped with a Tire Pressure Monitoring System (TPMS). Radio frequency noise is generated by electrical motors and appliance operation, cellular telephones, remote transmitters, power inverters and portable entertainment equipment.

Note. If a sensor does not respond to the Tire Pressure Monitor Activation Tool, attempt to activate the same sensor with the Tire Pressure Monitor Activation Tool. If the sensor still does not respond, move the vehicle to rotate the wheels at least one-fourth of a turn and attempt to activate the same sensor again.

Note. The SJB has a 2-minute time limit between sensor responses. If the SJB does not recognize any 1 of the 4 tire pressure sensors during this time limit, the horn will sound twice and the message center (if equipped) will display TIRE NOT TRAINED REPEAT and the entire procedure must be repeated.

Note. For vehicles with different front and rear tire pressures (such as the E-Series and certain F-Series), the tire pressure sensors must be trained following a tire rotation. Failure to train the sensors will cause the TPMS indicator to illuminate. For vehicles with the same tire pressure for front and rear tires, tire rotation will not affect the system.

1. Turn the ignition switch to the OFF position, then press and release the brake pedal.
2. Cycle the ignition switch from the OFF position to the RUN position 3 times, ending in the RUN position.
3. Press and release the brake pedal.
4. Turn the ignition switch to the OFF position.
5. Turn the ignition switch from the OFF position to the RUN position 3 times, ending in the RUN position. The horn will sound once and the TPMS indicator will flash if the training mode has been entered successfully. If equipped, the message center will display TRAIN LF TIRE.
6. Place the Tire Pressure Monitor Activation Tool on the LF tire sidewall opposite (180 degrees) from the valve stem. Press and release the test button on the Tire Pressure Monitor Activation Tool. The horn will sound briefly to indicate that the tire pressure sensor has been recognized by the SJB.
7. Within 2 minutes of the horn sounding, place the Tire Pressure Monitor Activation Tool on the RF tire sidewall opposite (180 degrees) from the valve stem and press and release the test button to train the RF tire pressure sensor.
8. Repeat Step 7 for the RR and LR tires. The procedure is completed after the last tire has been trained. When the training procedure is complete, the message center (if equipped) will display TIRE TRAINING COMPLETE. For vehicles not equipped with a message center, successful completion of the training procedure will be verified by turning the ignition switch to the OFF position without the horn sounding. If the horn sounds twice when the switch is turned to the OFF position, the training procedure was not successful.
9. Using the scan tool, locate the updated TPMS sensor identifiers trained to the SJB and document them on the applicable warranty claim.
10. If the sensors are being trained due to the installation of a new SJB, clear any DTCs and carry out the SJB On-Demand Self Test.
