Tire Pressure Sensor ID Registration

TIRE PRESSURE SENSOR ID REGISTRATION

When the TPMS transmitter or TPMS receiver are replaced, execute "Tire Pressure Sensor ID Registration." The TPMS won't function until the "Tire Pressure Sensor ID Registration" has been complete.

Required Special Tools:

- MB991958: Scan Tool (M.U.T.-III Sub Assembly)
- MB991824: Vehicle Communication Interface (V.C.I.)
- MB991827: M.U.T.-III USB Cable
- MB991910: M.U.T.-III Main Harness A

Register the tire pressure sensor IDs as described in the procedure below.

1. Select "4tires ID Reg. (Change tire PRS.)" and start the tire pressure sensor ID registration.

2.
CAUTION:
Register all tire pressure sensor IDs within twenty minutes.

"4 SNSR ID Registration Do you want to start? Note Finish ID Registration within 20 minutes." is displayed. Then, press "OK."
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.

3. 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 TPMS receiver.
NOTE:

- You can start out the following 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 M.U.T.-III screen.
- M.U.T.-III 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 M.U.T.-III 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 TPMS receiver may be faulty, thus replace the TPMS receiver.
- 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.

4. "4 SNSR ID Registration Completed." is displayed. Then, select "OK."
NOTE:
The TPMS indicator illuminates for tire pressure alarm.

5. After one minute or more has passed, correct the tire pressure for all wheels.

6. Check if the TPMS indicator goes out. If it does not go to, drive the vehicle for approximately 5 minutes, check the display again. If it still does not go out, register the ID code again.
