ID Registration ProcedureNES000GV
ID REGISTRATION WITH ACTIVATION TOOL
This procedure must be done after replacement of a transmitter, BCM or rotating wheels.
1. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
2. Select “AIR PRESSURE MONITOR” on “SELECT WORK ITEM”
3. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.
4. With the transmitter activation tool (J-45295) pushed against the front-left transmitter position of the air valve, press and hold the
button 5 seconds.
5. Register the IDs in order from FR LH, FR RH, RR RH to RR LH. When ID registration of each wheel has been completed, turn
signal lamp blinks.
6. After completing all ID registrations, press “END” to complete the procedure.
NOTE:
Be sure to register the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnostic results dis-
play will not function properly.

CAUTION:
This procedure must be done after replacement of a transmitter, BCM, or rotating wheels.
1. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
2. Select “AIR PRESSURE MONITOR” on “SELECT WORK ITEM”
3. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.
4. Adjust the tire pressure to the values shown in the table below for ID registration, and drive the vehicle at 40 km/h (25 MPH) or more for several minutes.
NOTE:
If ID registration is unable, buzzer beeps.
5. After completing all ID registrations, press “END” to complete the procedure.
6. Inflate all tires to proper pressure. Refer to WT-41, "

Transmitter Wake Up OperationNES000GW
WITH ACTIVATION TOOL
1. With the transmitter activation tool (J-45295) pushed against the
front-left transmitter, press the button for 5 seconds.

When ignition switch ON, as the low tire pressure warning
lamp blinks per the following diagram, the respective transmit-
ter then must be woken up.
2. Register the ID of wheel that low tire pressure warning lamp flashes. When wake up of registered wheel has been completed, turn signal lamp flashes two times.
3. After completing wake up all transmitters, make sure low tire pressure warning lamp goes out.

Self-DiagnosisNES000GX
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (BCM) of this
system has pressure judgment and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the
warning lamps in the combination meter comes on. To start the self-diagnostic results mode, ground terminal
of the tire pressure warning check connector. The malfunction location is indicated by the warning lamp flash-
ing and the buzzer sounds.

SELF-DIAGNOSTIC RESULTS MODE
NOTE:
Before performing the self-diagnosis, be sure to register the ID, or else the actual malfunction location may be different from that dis-
played on CONSULT-II.
How to Erase Self- diagnostic Results
1. Perform applicable inspection of malfunctioning item and then repair or replace.
2. Turn ignition switch “ON” and select “SELF-DIAG RESULTS” mode for “AIR PRESSURE MONITOR” with CONSULT-II.
3. Touch “ERASE” on CONSULT-II screen to erase DTC memory. CAUTION:
