ID Codes Registration Procedure

The contents of this article and images reflects the changes identified in TSB - 10-42a-003.

ID CODES REGISTRATION PROCEDURES

By operating the M.U.T.-III, the ID code registration and antenna communication can be performed.


CAUTION:
- If registered, starting the engine by using the conventional key becomes impossible. The new key will not be able to start the engine, too, because it has a different key groove.
- Do not register the emergency key and keyless operation key registered for other vehicles.


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.

2. Push the OK button after "Completed." Is displayed.



"COMM. TEST" METHOD







1. Select the antenna to be tested on "Communication Test" screen, and press the OK button with the keyless operation key placed within the communication operational area.

2. Push the OK button after "Communication is normal." is displayed.



"TIRE PRESSURE SENSOR ID REGISTRATION" METHOD



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



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


2. "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 WCM.


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 WCM may be faulty, thus replace the WCM.
- 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.




"TPMS TRANSMITTER CHECK" METHOD


According to the following procedures, identify which registered TPMS transmitter corresponds to which wheel, and check the tire pressure and acceleration value of each TPMS transmitter.


1. Check the data list "Air Pressure, Tire 1, 2, 3, 4" and write down the tire pressure for all wheels.



NOTE: The display at this time is the data received most recently.


2. Perform the following procedures for four wheels in order, identify the wheel by checking the tire pressure of each wheel.
(1) Change the pressure of tire for 20 kPa (2.9 psi) or more so that the TPMS transmitter sends the latest sensor data (The tire pressure can either be decreased or increased).
(2) Check the data list screen to determine which tire number corresponds to the wheel whose tire pressure has changed.


NOTE:
- It may take approximately one minute that the data of tire pressure change is displayed on the M.U.T.-III screen.
- If the data of tire pressure change is not displayed on the M.U.T.-III screen, the most possible cause is that the radio wave sent from the TPMS transmitter cannot be received. In this case, the radio wave may be received by performing the procedures from (1) again after turning the tire to change the TPMS transmitter position. If the tire pressure change is still not displayed on the M.U.T.-III screen, the TPMS transmitter in which the ID code is not registered may be installed, or the TPMS transmitter may be faulty. Therefore, perform ID code registration or replace the TPMS transmitter according to the instructions of troubleshooting for DICs. (At this time, do not register the ID codes or replace the TPMS transmitter.)



3. Check the tire pressure or acceleration value shown in the screen (if needed).


4. After checking by the tire pressure change, adjust the checked tire pressure to the proper value.




"TIRE PRESSURE SENSOR ID CHECK" METHOD



1. Select "Tire Pressure Sensor ID Check".


2. Check the registered TPMS transmitter IDs on the M.U.T.-III screen.



REGISTRATION NOT USING SCAN TOOL MB991958 (M.U.T.-III SUB ASSEMBLY) [USA ONLY]


When the keyless operation key is lost or additional keys are requested, the emergency key and the keyless operation key must be used to register key ID.



CAUTION: Two keyless operation keys that have been registered are needed.


1. Turn the ignition switch to the "ON" position using the registered emergency key and keyless operation key.


2. After turning the ignition switch to "ON," press and hold the UNLOCK button of the first registered keyless operation key for 4 to 10 seconds, and press the LOCK button during that time.


3. With in 10 seconds after pressing the LOCK button in Step 2, release the LOCK button and then UNLOCK button. (Perform within 30 seconds after completion of Step 1.)


4. Then, press and hold the UNLOCK button of the second registered keyless operation key for 4 to 10 seconds, and press the LOCK button during that time.


5. With in 10 seconds after pressing the LOCK button in Step 4, release the LOCK button and then UNLOCK button. (Perform within 30 seconds after completion of Step 3.)







6. The immobilizer indicator starts flashing, and the mode shifts to the keyless operation key additional registration mode.


7. Check that the immobilizer indicator flashes, and press the LOCK button of unregistered keyless operation key twice. KOS starts registration communication with the keyless operation key.


8. After the additional registration of keyless operation key is completed, the data is recorded to EEPROM, and when the data recording is completed, the immobilizer indicator flashes for 30 seconds.


9. When a new keyless operation key is additionally registered, repeat Steps 1 to 8 after the ignition switch is turned to "LOCK" (OFF).


1O. The keyless operation key addition is terminated if any of the following conditions is met.
- The additional registration of keyless operation key was completed.
- The signal of LOCK button operation was received from the keyless operation key which was registered in Step 8.
- Within 60 seconds after shift to the keyless operation key additional registration mode, the operation in Step 8 does not complete.
- Before the registration communication with unregistered keyless operation key starts, the ignition switch was turned to "LOCK" (OFF).
- The registration communication failed.
- The recording to EEPROM failed.
