When in standby mode, the sensors continue monitoring tire pressure, but do not transmit the information. If any tire pressure falls to one of the alarm
limits, a message is sent to the control module.
The sensors resume active mode when vehicle speed again exceeds 20 km/h.
Automatic teach-in
When warming up after start, the first period of the active mode is a teach-in procedure which lasts until each of the four sensors (which each have
their own unique code) is identified. This communication "teaches" the control module which sensor works with each wheel. This procedure takes
approximately 10 minutes. If the system cannot identify where the sensor it, it presumes that it is in the same position as it was the last time the car was
driven.
