TPMS Receiver Description and Operation

Operation

1. 1
   General Function

   • Auto-location/learning occurs only once per ignition cycle.
   • When completed successfully, the 4 road wheel sensor IDs along with their corresponding road wheel locations are stored in memory for monitoring.
   • Until auto-learning is completed, previously learned sensors (along with their corresponding locations) are monitored for low pressure / leakage warning.
   • Spare tire inflation / DTC status is not displayed.
2. 2
   General conditions for learning new sensors:

   • The receiver must automatically identify the 4 road wheel sensors.
   • Auto-location/learning operates only at speeds above 20 km/h.
   • The receiver must determine that it is confident the sensor is not temporary:

   a. Uses vehicle speed. b. Uses the confidence level of previously learned sensors.

   • Typical time to learn a new sensor when driving at speeds above 20 km/h is up to 10 minutes.
3. 3
   General conditions for canceling remote sensor learning:

   • It takes less than 10 minutes at a speed of 20-30 km/h.
   • Reduced reliability depends on the vehicle speed and the number of sensors known to the receiver.
