Sensors begin to give signals approximately in a minute after the speed of the movement exceeds 20 km/h. During the movement sensors give signals every other minute.

Sensors remain in an active state within 15 min. after a car stop, then pass into the mode on duty.

In this mode sensors give a signal if the difference of two in a row the measured sizes of pressure exceeds 68 Mbar or if pressure from the moment of delivery of the last signal changed more than on 68 Mbar (as a result of cooling of tires).

Tires are considered cold in 1 h 45 min. after a car stop.

The minimum time of detection of leak of air makes about 15 min. of tires.

The message "Pump up tires for movement along the highway" is given (for reference) if the car moves with a speed over 170 km/h within 3 min. and if pressure at least in one tire on 400 Mbar below of the movement provided for small speed. This message is not given at any speed of the movement if pressure for driving on highways is installed in tires.

Threshold sizes of giving of the warning signals:

– pressure in cold tires is higher than norm = pressure in tires is higher ordered on 700 Mbar;

– pressure in the warmed tires is higher than norm = pressure in tires is higher ordered on 850 Mbar;

– pressure in tires is lower than norm = pressure in tires is lower ordered on 400 Mbar;

– pressure in tires is much lower than norm = pressure in tires is lower ordered on 600 Mbar;

– different pressure in tires = pressure difference in the left and right wheel of one axis is more than 500 Mbar.

– The messages displayed on a board:

– "A puncture, replace a wheel" + fire of an alarm lamp of STOP + highlighting of the image of the corresponding wheel with a board in a guard of devices + a sound signal;

– "Install the required pressure in tires" + highlighting of the image of the corresponding wheel on a board;

– "Pump up tires for movement along the highway" + highlighting of images of all wheels on a board;

– "The tire sensor" + blackout of the image of the corresponding wheel is faulty;

– "Malfunction of electronics" + fire of an alarm lamp of "service" + blackout of images of the corresponding wheels on a board.

Information on pressure in tires on a guard of devices is not output.
