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
scan tool screen.

•

Scan tool 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 scan tool 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 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 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 scan tool
screen.

•

If the data of tire pressure change is not displayed on
the scan tool 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 scan tool 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 scan tool

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. 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.
