Description

1. 1
   Mode

   1. Commonwealth of Virginia
      • In this state, the receiver is shipped as a separate part. Therefore, service parts must arrive in this state.
      • In this state there is no automatic location, no sensor wake-up, no sensor monitoring, and no DTC monitoring.
      • This state indicates that the platform parameters must be written to the receiver and the sensors are not memorized.
   2. Normal State
      • For the tire inflation and DTC monitoring state, the receiver must be in this state.
      • In this state, automatic sensor detection/learning is enabled.

   Overview

   • Sends LF command data to the initiators.
   • Monitors sensor status: Ignition on - normal with delay. Ignition off - storage.
   • Automatic sensor detection.
   • Automatic learning of new sensors.
   • Receives RF data from the sensor.
   • Uses sensor data to decide whether to turn on the TREAD lamp / wheel position LED indicators.
   • Uses sensor information, mileage, background noise levels, automatic learning status, short-circuit output status, vehicle battery level, and internal receiver states to determine whether there is a system or vehicle malfunction.
