Hyundai Ioniq (AE) 2017-2024 Service Manual / Suspension System / Tire Pressure Monitoring System / TPMS Sensor. Repair procedures

Replacement

1.	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.

4.	The valve during transportation (air inlet portion of the silver) deviated from its original location be sure to check whether the original position of the valve (metal brackets) are assembled in indented state.

5.	While tightening the nut on the valve as not to deviate from the fixed position while rotating the valve to a fixed location (metal brackets to fit inside) and push.

6.	Contact with the rim so that the valve washer seals the valve hole put into.

7.	Housing with two fingers holding the valve in the axial direction with one finger and push the valve.

8.	Housing, the state must be visible laser marking.

9.	When the valve is fully inserted so that the contact between the sensor and the rim while keeping hands on the wheel nut tightening will start Wed.

10.

While maintaining the position of the valve and the sensor is mounted nut.

Tightening torque :

68.6 - 88.3 N.m (7.0 - 9.0 kgf.m, 50.6 - 65.1 lb-ft)

11.	Remove the tire change machine.

12.

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

Tier pressure : 2.5 kg/cm³ (36 psi)

13.	In the case of TPMS sensor failure, TPMS sensor needs learning. Faulty sensor is replaced new units, conduct learning of TPMS sensors.

Inspection

After installing TPMS sensor test methods Thai

1.	Sealing washer on the outside rim of hole to be compressed.

2.	The lower part of the valve housing, a fixed place (no metal brackets) should be located.

3.	Housing is at least one or more points on the surface of the rim should contact.

4.	The rim of the housing mounting height shall not exceed the height of the chin. [Normally] [Faulty]

Diagnosis procedure by using diagnostic device

As manual for diagnosis methods by using diagnosis device, the main contents are as follows:

1.	Connect self-diagnosis connector(16pins) located in the lower of driver side crash pad to self-diagnosis device, and then turn the self-diagnosis device after key is ON.

2.	Select the "vehicle model" and "TPMS" on GDS vehicle selection screen, then select OK.

Diagnostic Procedure Using a Diagnostic Instrument

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