1. Mode
   1. Virgin State
      • The receiver as a sole part is shipped in this state. Replacement parts should therefore arrive in this state.
      • In this state, there is no Auto-Location, no sensor wake-up, no sensor monitoring and no DTC monitoring.
      • The state indicates that platform specific parameters must be written to the receiver and that sensors are un-learned.
   2. Normal State
      • In order for tire inflation state and DTC monitoring to occur, the receiver must be in this state.
      • In this state, automatic sensor location/learning is enabled.
2. Overview
   • Learn TPMS sensor for under inflation monitoring automatically.
   • Uses sensor information, distance travelled, background noise levels, Auto-learn status, short/open circuit output status, vehicle battery level, internal receiver states to determine if there is a system or a vehicle fault.
