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

Hyundai Ioniq (AE) 2017-2025 Service 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).

    DescriptionCrankshaft Position Sensor (CKPS) detects the crankshaft position and is one of the most important sensors of the engine control system. If there is no CKPS signal input, the engine may stop because of CKPS signal missing.This sensor is installed in ladder frame and generates alternating current by magnetic flux field which is made by the sensor and the target wheel when the engine rotates...

    Tilt Steering / Telescope Steering

    Adjust the steering wheel so it points toward your chest, not toward your face. Make sure you can see the instrument cluster warning lights and gauges. After adjusting, push the steering wheel both up and down to be certain it is locked in position. Always adjust the position of the steering wheel before driving.

    WARNING

    NEVER adjust the steering wheel while driving. This may cause loss of vehicle control resulting in an accident.
