Tire Pressure Sensor ID Registration
"Tire Pressure Sensor ID Registration" METHOD
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
By operating the scan tool MB991958 (M.U.T.-III sub assembly) screen, the ID code registration and the TPMS can be registered and antenna communication required to the keyless operation system can be performed. KOS and keyless operation key are indicated as F.A.S.T and F.A.S.T.-key respectively in the scan tool MB991958 (M.U.T.-III sub assembly) screen.
CAUTION:
Do not register the keyless operation key registered for other vehicles.
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 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 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 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.
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 with ignition switch "ON".
6. 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.
