Sorento 2WD V6-3.3L (2008)
Tire Pressure Monitor Receiver / Transponder: Description and Operation
TPMS Receiver
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. Sends LF command data to initiators.
B. Controls sensor state:
Ignition on - Normal Delayed
Ignition off - Storage.
C. Auto-Locates sensors.
D. Auto-Learns new sensors.
E. Receives RF data from sensor.
F. Uses sensor data to decide whether to turn on TREAD Lamp / wheel location LED's.
G. Uses sensor information, distance traveled, background noise levels, Auto-learn status, short 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 + 1 spare, 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.
D. Spare tire inflation / DTC state is not displayed.
