Hyundai Venue. TPMS Receiver. Description and operation

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.
Operation
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).

    Replacement 1. Remove the wheel and tire. 2. Remove the valve core and deflate the tire. 3.

    Replacement [TPMS Receiver (Integrated Body Control Unit (IBU))] 1. Turn the ignition switch OFF and disconnect the battery negative (-) cable.
