Tire Pressure Sensor: Service and Repair

Removal

CAUTION:
Handle the sensor with care.

1. Remove the tire.
2. Remove the valve nut.





CAUTION:
The valve nut should not be re-used.

3. Discard the valve assembly.

Replacement

Repair tire after using the Tire Mobility Kit (TMK)

When the TPMS warning lamp OFF
1. Remove the TMK repaired tire, wheel and TPMS sensor.

2. Remove the sealant on the wheel and TPMS sensor (A) completely.

CAUTION:
- Clean the sealant on the housing and sensing hole of TPMS sensor with clean cloth, gauze or air inhalers.
- To prevent the sensor and circuit board damage, do not use the pointed instrument and give a lot of impact.




3. Install the TPMS sensor to the new tire.
4. Check that the normal operation of TPMS system.

When the TPMS warning lamp ON
1. Remove the TMK repaired tire, wheel and TPMS sensor.

2. Remove the sealant on the wheel and TPMS sensor (A) completely.

CAUTION:
- Clean the sealant on the housing and sensing hole of TPMS sensor with clean cloth, gauze or air inhalers.
- To prevent the sensor and circuit board damage, do not use the pointed instrument and give a lot of impact.




3. Install the TPMS sensor to the new tire.
4. Check the tire pressure using the electrical tire pressure gauge.
5. Check the tire pressure of TPMS sensor using the GDS
6. If the difference between two checked pressures in the above is not more than 2 psi, TPMS sensor is normal. Reinstall it to new tire.
7. If the difference between two checked pressures in the above is more than 2 psi, TPMS sensor is abnormal. Install new TPMS sensor to new tire.
8. Check that the normal operation of TPMS system.

Installation

Sensor Fit

CAUTION:
- Handle the sensor with care.
- Avoid lubricant contact.
- Ensure that the wheel to be fitted is designed for sensor mount. There should normally be a mark to indicate this.
- Ensure that the valve hole and mating face of the wheel are clean.

1. Slide the sensor-valve unit through the valve hole of the rim. Hold the sensor against the rim and the rubber grommet against the sealing surface.
2. Insert the nut over the valve stem and then tighten the nut.




3. Continue to tightening the nut until contact with the rim and then tighten to 3.5 - 4.5Nm.





CAUTION:
- Tighten slowly with quarter turn steps until the final torque is reached.
- Do not exceed allowed torque.
- Do not use electric or pneumatic tools.

4. Check that the sensor is firmly attached to the rim.

CAUTION:
Risk of damage during the tire installation/ removal if the sensor is not firmly attached to the rim.

5. Carry out inflation / pressure correction and then fit valve cap.

CAUTION:
Change the newly installed sensor mode to Normal Fixed Base(Low Line) with the 'GDS'.
Mode (Status / option) of the sensor installed to the vehicle should be Normal Fixed Base (Low).

6. Install the tire.
7. In the case of TPMS sensor failure, TPMS sensor needs learning. Faulty sensor is replaced new units, conduct learning of TPMS sensors.

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.

NOTE:
- In North America, the cable is measured separately.
- In Domestic/General(European) area, the cable is measured without separation.

NOTE:
- Each entry must check whether each sensor normal.
- After replacing the tires or sensors, check the status of sensor is working properly after sensor registration process.
