TPMS Receiver: Operation

WARNING: This page is about a different variant/trim than selected.
  1. General Function
    • Auto-locate/learn takes place only once per Ignition cycle.
    • On successful completion, 4 road wheel sensor ID's + 1 spare, together with their respective road wheel positions are latched into memory for monitoring.
    • Until Auto-learn completes, previously learned sensors (together with their respective locations) are monitored for under inflation/leak warnings.
    • Spare tire inflation/DTC state is not displayed.
    • Spare tire DTC's are available through diagnostics only.
  2. General Conditions to Learn New Sensors:
    • Receiver must Auto-Locate 4 road sensors.
    • Auto-location/learning only functions when speed is more than 20 kph (approx. 15 mph).
    • Receiver must determine that it is confident that sensor is not temporary:
      1. Uses vehicle speed.
      2. Uses confidence reduction of previously learned sensors.
    • Typical time at driving over 20 kph to learn a new sensor is up to 10 minutes.
  3. General Conditions to Un-Learn a sensor that is removed:
    • It takes less than 10 minutes at 20-30kph.
    • Confidence reduction is dependent on vehicle speed and the number of sensors known to the receiver.
