2006 Mercury Mariner Mercury Mariner TPMS

Hello. Thanks for the donation. Much appreciated

You cannot disable the TPMS. You need a special tool to reset the system (some tire replacement stores can now reset these sytems)

TPMS RESET - PROCEDURE 1
NOTE:In the following procedure, TPM Activation Tool (204-363) or equivalent must be used.

NOTE:If tire pressure sensor is replaced, it will need to be trained. The TPM system is not affected by wheel and tire rotation.

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 3 ft. (1 m) away from any other vehicle equipped with TPM system. RF noise is generated by electrical motor and appliance operation, cellular telephones and remote transmitters, power inverters and portable entertainment equipment.

NOTE:A new tire pressure sensor is shipped in an OFF mode (or battery saver mode), and must be turned ON before it can be trained. To turn the sensor on, inflate the tire to the recommended inflation pressure and wait at least 2 minutes, then continue with the sensor training procedure.

Turn ignition switch to OFF position, then press and release brake pedal.
Turn ignition switch from OFF position to the RUN position 3 times, ending in RUN position. Do not wait more than one minute between each key cycle.
Press and release the brake pedal.
Turn ignition switch to OFF position.
Turn ignition switch from OFF position to the RUN position 3 times, ending in 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 activation tool must remain in place 180 degrees from the valve stem. See Fig. 1.

NOTE:If a sensor does not respond to the activation tool, attempt to activate the same sensor using activation tool. If the sensor still does not respond, move the vehicle to rotate the wheels at least 1/4 of a turn and attempt to activate the same sensor again.

NOTE:If the SJB does not recognize any one of the 4 tire pressure sensors during the tire training procedure, the horn will sound twice and the message center (if equipped) will display "TIRE NOT TRAINED REPEAT". Repeat training procedure from the beginning.

The horn will sound once and the tire pressure warning light will flash if train mode has been entered successfully (if equipped, the message center displays "TRAIN LF TIRE"). Place TPM Activation Tool (204-363) on the left front tire wall opposite (180 degrees) from the valve stem. The horn will sound briefly to indicate that the tire pressure sensor has been recognized by the SJB.
NOTE:Do not wait more than 2 minutes between training each sensor.

Within 2 minutes after the horn sounds, place the activation tool on the right front tire wall opposite (180 degrees) from the valve stem. Repeat procedure for right rear and left rear tires. See Fig. 2.
When the tire training procedure is complete, the message center (if equipped) will display "TIRE TRAINING MODE 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 when ignition is turned off, the training procedure was not successful.
