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

Hyundai Kona (OS) 2018-2025 Service Manual / Suspension System (NON-ECS) / Tire Pressure Monitoring System / TPMS Receiver Description and operation

Description

TPMS Receiver : BCM(body control module) integrated management

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.

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

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.

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.

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).
