Hyundai Ioniq (AE) 2017-2022 Service & Repair Manual / Suspension System / 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).

    Replacement1.Remove the valve core and deflate the tire.2.Push the tire as illustration below by using tive change machine.3.Loosen the nut and then remove the TPMS sensor.
