Second generation VI (2009–2026) / Hyundai Equus VI 2009-2026 Service Manual / Suspension System / Tire Pressure Monitoring System / TPMS Receiver Description and Operation

Description

1.
Mode
(1)
Virgin State
A.
The receiver as a sole part is shipped in this state. Replacement parts should therefore arrive in this state.
B.
In this state, there is no Auto-Location, no sensor wake-up, no sensor monitoring and no DTC monitoring..
C.
The state indicates that platform specific parameters must be written to the receiver and that sensors are un-learned.
(2)
Normal State
A.
In order for tire inflation state and DTC monitoring to occur, the receiver must be in this state.
B.
In this state, automatic sensor location / learning is enabled.
2.
Overview
A.
Receives RF data from sensor.
B.
Uses sensor data to decide whether to turn on TREAD Lamp.
C.
Learn TPM sensor for under inflation monitoring automatically.
D.
Uses sensor information, 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
A.
Auto-locate/learn takes place only once per Ignition cycle.
B.
On successful completion, 4 road wheel sensor ID's, together with their respective road wheel positions are latched into memory for monitoring.
C.
Until Auto-learn completes, previously learned sensors (together with their respective locations) are monitored for under inflation / leak warnings.
2.
General Conditions to Learn New Sensors:
A.
Receiver must Auto-Locate 4 road sensors.
B.
Auto-location / learning only functions when speed is more than 25 kph (approx. 15 mph).
C.
Receiver must determine that it is confident that sensor is not temporary:
1)
Uses vehicle speed.
2)
Uses confidence reduction of previously learned sensors.
D.
Typical time at driving over 25 kph (15.5mph) to learn a new sensor is up to 10 minutes.
3.
General Conditions to Un-Learn a sensor that is removed:
A.
It takes less than 10 minutes at 20~25kph. (15 ~ 15.5mph)
B.
Confidence reduction is dependant on vehicle speed and the number of sensors known to the receiver.
