Hyundai Kona: Tire Pressure Monitoring System / TPMS Receiver Description and operation

Description
TPMS Receiver : BCM(body control module) integrated management

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).

Hyundai Kona (OS) 2018-2020 Owners Manual: Tire rotation
To equalize tread wear, HYUNDAI recommends that the tires be rotated every 12,000 km (7,500 miles) or sooner if irregular wear develops. During rotation, check the tires for correct balance. When rotating tires, check for uneven wear and damage. Abnormal wear is usually caused by incorrect tire p ...
