Tire Pressure Sensor: Description and Operation

DESCRIPTION





1. MODE
1) Stationary/Rolling mode
^ Measure pressure and temperature every 4 seconds.
^ Measure acceleration every 60 seconds.
^ High line TPMS sensors transmit data every 60 seconds while awake.

2) Sleep mode
^ This state is a Low current consumption state.
^ Sensors are in this state when they first arrive at the dealership (either on the vehicle or as replacement spares).
^ In this state, the sensor does not measure pressure / temperature / battery level.
^ The sensor will not transmit in this state unless requested to do so by the initiate command or woken by acceleration > 20 mph.
^ Measure acceleration every 60 seconds.
^ High line sensors return to this state if no LFI signals and the tire remains stationary for > 10 minutes to conserve battery power.
