пробить колесо может и на МКАДе.
Гораздо эффективнее обнаржить начало сдутия колеса по приборам, чем по поведению машины. (я каждую неделю проверяю давление, перед поездкой на дачу)
так что для меня иметь датчики в колёсах - более актуально, чем проверять манометром или "на глазок".
что-то не могу найти где у нас физически находится WCM модуль.
The wireless control module (WCM) is a system that integrates the keyless entry function, immobilizer function, and the TPMS function.
Controls the keyless entry functions, TPMS functions and starting of the engine by using the following communications.
•Communications with ETACS-ECU, ECM, ABS-ECU <vehicles for ABS> and combination meter via CAN
•Wireless communication with the ignition key (transmitter)
•Wireless communication with the TPMS transmitter

The signals from the TPMS transmitter are received by the WCM.
•WCM processes input signals from each TPMS transmitter as well as vehicle speed signals from the ABS-ECU if equipped. It receives the atmospheric
pressure signal from ECM, and when the atmospheric pressure is low (such as at high altitude),
it calibrates the tire pressure received from TPMS transmitter and makes a judgment of warning. When the road tire pressure is low, it sends a warning signal causing the TPMS warning
light to be illuminated. When the TPMS has problems, it sends a warning signal causing the TPMS warning light to be flashed*.
NOTE:
*: Change to continuous illumination after flashing for about 1 minute.
•For 3 seconds after the ignition switch is turned to the "ON" position, WCM illuminates the TPMS warning light to check any breaks in the TPMS warning light circuit.
By connecting the scan tool to the data link connector,
data stored in WCM (data of tire pressure and TPMS transmitter ID, the alarm status and warning history, etc.) can be displayed and TPMS transmitter ID can be registered.
NOTE:
If the TPMS transmitter is replaced, regis
ter the ID codes of all the TPMS transmitters again using the M.U.T.-III.

На движущейся машине опрос датчиков идёт 1 раз в 1 мин. На стоячей машине - 1 раз в 13 часов.
