SUBJECT VEHICLES: Ford Taurus 2011-19, Ford Police Interceptor Sedan 2014-19, Ford Special Service Police Sedan 2015-17, and Lincoln MKS 2011-16.
SPECIAL TOOLS NEEDED? Yes, a TPMS activation tool (204-363) must be used.
The tire pressure monitoring system (TPMS) monitors the air pressure in the four 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).
NOTE: The smart junction box is also known as the generic electronic module (GEM).
Under the following conditions, the TPMS may not function properly:
- Low tire pressure.
- The tire pressure sensor is missing or damaged.
- A spare tire is installed as a road wheel.
- An incorrect tire pressure sensor is installed.
- A tire pressure sensor is installed incorrectly.
- Non-OEM wheels are installed (aftermarket rims).
- Non-OEM equipped run-flat tires are installed.
- There are other non-OEM modifications (roll cages, service barriers, part racks, ladder racks, etc.).
TIRE PRESSURE MONITOR WARNING LIGHT
NOTE: As ambient temperature decreases by 10 degrees Fahrenheit (6 degrees Celsius), tire pressure decreases 1 psi (7 kPa). If tire pressures are not adjusted at cold temperature, the tire pressure may drop enough to be detected by the TPMS, which will activate the low pressure warning light.
When the tire pressure warning light comes on solid and the message center displays “LOW TIRE PRESSURE,” check the air pressure of all the tires and adjust to the specified cold pressure listed on the vehicle certification label (found on the driver’s door or door pillar). Drive the vehicle at 20 mph (32 km/h) for at least 2 minutes. Make sure the warning light goes off. If the warning light stays on, there is a malfunction in the TPMS. See the appropriate manufacturer service information. The TPMS warning indicator flashes for 70 seconds, then remains on continuously when the ignition is turned to the ON position if the TPMS is malfunctioning. The following messages indicate a system malfunction:
- Tire pressure sensor fault — The message center displays TIRE PRESSURE SENSOR FAULT when a TPMS sensor is malfunctioning.
- No communication with the BCM — The TPMS warning indicator illuminates when the IPC has not received any signals from the BCM for more than 5 seconds. The message center displays TIRE PRESSURE MONITOR FAULT.
- Tire pressure monitor fault — The message center displays TIRE PRESSURE MONITOR FAULT when the TPMS is malfunctioning. See the appropriate manufacturer service information.
TPMS RESET PROCEDURES
NOTE: If the tire pressure sensor is replaced, it will need to be trained. Training the sensors is not necessary after a tire rotation on vehicles with the same front and rear tire pressures, but the BCM cannot recognize that the sensor identifiers have been moved to different positions, it only retains the original position the sensors were last trained to.
NOTE: Do not use the TPMS reset procedure outlined in the owner’s literature as this procedure will not program new sensors to the module.
When the tire pressure warning light comes on solid and the message center displays “LOW TIRE PRESSURE,” check the air pressure of all tires and adjust to the specified cold pressure listed on the vehicle certification label (found on the driver’s door or door pillar). Drive the vehicle at 20 mph (32 km/h) for at least 2 minutes. Make sure the warning light goes off.
TIRE PRESSURE SENSOR REGISTRATION
NOTE: In the following procedure, a TPMS activation tool (204-363) must be used.
NOTE: The tire pressure sensor training procedure must be done on a single vehicle, in an area without radio frequency (RF) noise and at least three feet away from any other vehicle equipped with a TPMS. RF noise is generated by an electrical motor and appliance operation, cellular telephones and remote transmitters, power inverters and portable entertainment equipment.
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 body control module (BCM). Refer to “Tire pressure sensor activation.”
NOTE: If a sensor does not respond to the TPMS activation tool, attempt to activate the same sensor with the TPMS activation tool.
If the sensor still does not respond, move the vehicle to rotate the wheels at least one-fourth turn and attempt to activate the same sensor again.
NOTE: The body control module (BCM) has a 2-minute time limit between sensor responses. If the BCM 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.
Vehicles with intelligent access (IA):
1) Set the tire pressure of all wheels to the pressure specified on the tire and loading information label.
2) Close all doors.
3) Turn the ignition switch to the OFF position, then press and release the brake pedal.
4) Using the START/STOP button, switch from the OFF to ACCESSORY to RUN position 3 times, ending in the RUN position.
5) Press and release the brake pedal.
6) Turn the ignition switch to the OFF position.
7) Using the START/STOP button, switch from the OFF to ACCESSORY to RUN position 3 times, ending in the RUN position.
NOTE: It may take up to 6 seconds to activate a tire pressure sensor. During this time, the TPMS activation tool must remain in place at the valve stem.
8) Place the TPMS activation tool on the left front tire wall at the valve stem. Press the “TEST” button. The horn will sound briefly to indicate that the tire pressure sensor has been recognized.
NOTE: Do not wait more than 2 minutes between training each sensor or the BCM will time out and the entire procedure must be repeated.
9) Within 2 minutes after the horn sounds, place the TPMS activation tool on the right front tire wall at the valve stem. Then press the test button to train the right front tire pressure sensor. Repeat this procedure for the right rear and left rear tires, in that order.
10) When the tire 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 ignition is turned off, the training procedure was not successful.
Vehicles with integrated key head transmitter (IKT):
1) Set the tire pressure of all wheels to the pressure specified on the tire and loading information label.
2) Turn the ignition switch to OFF, then press and release the brake pedal.
3) Turn the ignition switch from the OFF position to the RUN position 3 times ending in the RUN position. Do not wait more than one minute between each key cycle.
4) Press and release the brake pedal.
5) Turn the ignition switch to the OFF position.
NOTE: 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) Turn the ignition switch from the OFF position to the RUN position 3 times, ending in the RUN position. Do not wait more than one minute between each key cycle.
NOTE: It may take up to 6 seconds to activate a tire pressure sensor. During this time, the TPMS activation tool must remain in place at the valve stem.
7) Place the TPMS activation tool on the left front tire wall at the valve stem. Press the “TEST” button. The horn will sound briefly to indicate that the tire pressure sensor has been recognized by the DDM.
NOTE: Do not wait more than 2 minutes between training each sensor or the BCM will time out and the entire procedure must be repeated.
8) Within 2 minutes after the horn sounds, place the TPMS activation tool on the right front tire wall at the valve stem. Then press the test button to train the right front tire pressure sensor. Repeat this procedure for the right rear and left rear tires, in that order.
9) When the tire 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 ignition is turned off, the training procedure was not successful.
