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.
1.General Function
• Auto-learn takes place only once per Ignition cycle.
• On successful completion, 4 road wheel sensor ID's are latched into memory for monitoring.
• Until Auto-learn completes, previously learned sensors are monitored for under inflation / leak warnings.
2.General Conditions to Learn New Sensors:
• Receiver must determine that it is confident that sensor is not temporary:a. Uses vehicle speed.b. Uses confidence reduction of previously learned sensors.
• Typical time at driving continuously over 15.5 mph(25 kph) to learn a new sensor is up to 20 minutes.
3.General Conditions to Un-Learn a sensor that is removed :
• It takes less than 20 minutes at 15.5 mph(20-30 kph).
• Confidence reduction is dependent on time which vehicle is driven at speed greater than or equal to 12.4 mph(20-30 kph).
