Tire Pressure Sensor Registration
NOTE:
If the Wireless Control Module (WCM), the Keyless Operation System (KOS), or transmitter is replaced, the tire pressure sensors must be registered.
The following tools are required when performing the tire pressure registration:
- Scan Tool (MUT-III Sub Assembly) (MB991958)
- Vehicle Communication Interface (V.C.I.) (MB991824)
- MUT-III USB Cable (MB991827)
- MUT-III Main Harness A (MB991910)
CAUTION:
To prevent damage to Scan Tool (MB991958), always turn ignition switch to OFF position before connecting or disconnecting scan tool.
- Connect MUT III scan tool. See Fig 1. Turn igntion switch to ON postion. From the "Special Functions" screen, select "Tire Pressure Sensor ID Registration".
- Select "4tires ID Reg. (Change tire PRS.)" and start the tire pressure sensor ID registration.NOTE: If the ID code registration is not finished within 20 minutes, all the ID codes registered in the TPMS transmitter before will be erased. For this reason, the ID codes need to be registered again.
- Decrease the tire pressure to 174 kPa (25.2 psi) or less by changing 20 kPa (2.9 psi) or more, and register the TPMS transmitter ID code of each wheel to KOS-ECU.NOTE:
- You can start out the operations from any TPMS transmitter. The tire pressure sensor ID registration has no order.
- On completion of the TPMS transmitter ID code registration, the TPMS transmitter ID code is displayed on the scan tool screen.
- Scan tool cannot identify which registered TPMS transmitter is used for each wheel. For this reason, write down the tire number for each wheel when the tire number and ID code is displayed on the scan tool during ID code registration.
- It may take approximately one minute for the ID code to be displayed on the scan tool screen after the tire pressure is reduced.
- If the ID code is not displayed, reduce the tire pressure another 20 kPa (2.9 psi) or more. If the ID code is not displayed yet, rotate the tire to displace the TPMS transmitter, and reduce the tire pressure 20 kPa (2.9 psi) or more again.
- If the ID code cannot be registered for all the four wheels, the KOS-ECU may be faulty, thus replace the KOS-ECU.
- If the ID code can be registered for one wheel or more, the TPMS transmitter in which the code cannot be registered may be faulty, thus replace that TPMS transmitter.
- When "4 SNSR ID Registration Completed." is displayed. Then, select "OK".
- After one minute or more has passed, correct the tire pressure for all wheels with ignition switch "ON".
- Check the data list "Registered ID reception, Tire 1, 2, 3, 4" if "YES" is displayed for each tire. When "NO" is displayed, drive the vehicle for approximately 5 minutes, check the display again. If "NO" is still displayed, register the ID code again.
