5. Check the number of the registered keys and keyless 

operation keys.

NOTE: When the key cannot be registered using scan tool 
MB991958, refer to Inspection Procedure 2 "The keyless oper-
ation key cannot be registered using scan tool 

P.42B-174

"STEERING LOCK UNIT REG." METHOD

1. Enter the password on "Steering Lock Unit Registration" 

screen and press the OK button to register the KOS ID.

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 min-
utes.
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 KOS-ECU. 
NOTE: 

.

You can start out the operations from any TPMS trans-
mitter. The tire pressure sensor ID registration has no 
order.

On completion of the TPMS transmitter ID code registra-
tion, the TPMS transmitter ID code is displayed on the 
M.U.T.-III screen.

M.U.T.-III cannot identify which registered TPMS trans-
mitter 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 reg-
istration.

It may take approximately one minute for the ID code to 
be displayed on the M.U.T.-III screen after the tire pres-
sure 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 trans-
mitter, 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 wiring harness or connector between the 
receiver antenna assembly and KOS-ECU, the receiver 
antenna assembly or the KOS-ECU may be faulty.  In 
this case, check DTC as DTC from KOS-ECU may be 
set. (Refer to 

P.42B-20

.)

If the ID code can be registered for one wheel or more, 
the TPMS transmitter in which the code cannot be regis-
tered 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, Tire1, 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 dis-
played 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 DTCs. (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 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. Within 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. Within 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).

10.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.
