Kia Stinger: Tire Pressure Monitoring System / TPMS Sensor

Kia Stinger CK 2018-2020 Service Manual / Suspension System / Tire Pressure Monitoring System / TPMS Sensor

Description and operation
Description

1.

Function

By detecting the pressure, temperature, acceleration, and battery condition, transmit information to ECU by a wireless RF.

Wheel location is recognized by comparing the Wheel Pulse of ECS (ABS) and acceleration values of the sensor (High Line).

2.

Structure and features

There are four (4) sensors mounted in each wheel of the vehicle.

Frequency conversion type is FSK, and High Line is used in common.

TPMS Automatic Location Learning

Wheel angular velocity of wheels are different from each other in the following cases:

1)

Slip for each axis occurs differently.

2)

Rotation radius (the radius of curve) for each wheel is different.

3)

Tire wear, internal pressure, tire specifications, etc. for each tire are different.

TPMS sensor is transmitted to RF signal at only specific phase (the angle of the tire) in the learning mode.

TPMS receiver checks each tire phase (tire angle) information on receiving RF signals from the sensor.

Every time RF signals from sensor IDs 1, 2, 3, and 4 are received, the ID with the highest correlation among the phase of each collected wheel is transmitted. (In other words, each time RF signal is received, the phase of the tire is transmitted to the most constant wheel.)

TPMS sensor transmits the RF signal at intervals of 16 seconds in the learning mode.

After stopping or parking for more than 19 minutes, automatic learning function in every driving position is performed.

The sensor is converted to Parking Mode when stopped or parked for more than 15 minutes. When acceleration of over 4g (15-20km/h) is detected in Parking Mode, it is converted to First Block Mode.

Repair procedures
Removal
1.

Remove the tire.

(Refer to Tires/Wheels - "Tire")

2.

Remove the screw with torx driver (A).

  

When installing the bead brake, make sure that it does not come in contact with the TPMS sensor.

Be careful not to damage the TPMS sensor when installing the bead brake near the TPMS sensor.

3.

Remove the sensor body (A) from the valve (B) in the direction of the arrow.

4.

Use the valve mounting tool to pull out the valve until it is entirely out of the lower hole.

  

Cut the rubber(A) at the bottom of valve with a knife.

5.

Apply lubricant to the surface of the valve, and then mount it through the valve hole of the wheel.

  

We recommend using regular soapy water as lubricant.

  

The TPMS sensor valve bottom is not properly sealed if it is not fully mounted on the wheel, as shown in the following figure:

Make sure that the valve body is pulled entirely through the hole.

6.

Apply soapy water or lubricant to the upper/lower bead section of the tire.

7.

In order to mount lower the beads, place the TPMS sensor at 5 o'clock, starting from the head of the tire replacement equipment.

8.

Rotate the rim clockwise and press tire towards 3 o'clock to mount the lower beads.

  

Mount the tire on the wheel. Make sure that the beads touch the edge of the rim behind the sensor (towards 6 o'clock).

9.

In order to mount the upper beads, press the tire towards 3 o'clock and turn the rim clockwise.

10.

Inject air into the tire until the beads are in the correct position.

11.

Adjust the tire pressure according to the recommended tire pressure for the vehicle.

12.

If the TPMS sensor malfunctions, you must perform TPMS sensor learning. Replace any faulty sensors and perform TPMS sensor learning.

Inspection

Test procedures after installing TPMS sensor

1.

The sealing washer should be compressed on the outside rim of the hole.

2.

The lower part of the valve should be located in a specified place (no metal brackets).

3.

The housing should contact at least one or more points of the rim surface.

4.

The rim of the housing mounting height shall not exceed the height of the chin.

Diagnostic Procedure Using a Diagnostic Instrument

The following section describes how to diagnose faults using a diagnostic instrument.

1.

Connect the diagnostic instrument to the self-diagnostic connector (16-pin) beneath the crash pad on the side of driver's seat, and then turn on the ignition to activate the diagnostic instrument.

2.

In the KDS Vehicle Type Selection menu, select "Vehicle Type" and "TPMS" System, and then opt for "OK."

[Register Sensor Method]

  

Check that Write ID and Read ID are the match.

After successfully registering the sensor, perform "Sensor Wireless Information" to confirm that the sensor operates properly.

[Sensor Status Method]

  

Each entry must be checked for normal operation of each sensor.

After replacing the tires or sensors, check for proper operation of sensor after sensor registration process.
