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 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 learning is enabled.
3. Test State
  - This state is only used in manufacturing plant to check RF transmission between sensor and receiver.
Overview
- Receives RF data from sensor.
- Uses sensor data to decide whether to turn on TREAD Lamp.
- Learn TPM 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.
