ID Registration ProcedureAES000Z5
ID REGISTRATION WITH ACTIVATION TOOL
This procedure must be done after replacement of a transmitter or BCM.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunction might be detected
during self-diagnosis depending on control unit which performs CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CONSULT-II CONVERTER to the data link con- nector, then turn the ignition switch ON.
2. Select “START (NISSAN BASED VHCL)”.
3. Select “BCM” on “SELECT SYSTEM” screen. NOTE:
If “BCM” is not indicated, go to GI-39, "
CONSULT-II Data Link Connector (DLC) Circuit" .
4. Select “AIR PRESSURE MONITOR” on “SELECT WORK ITEM” screen.
5. Select “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.
6. With the activation tool (J-45295) pushed against the front-left transmitter position of the tire air valve, press and hold the but-
ton 5 seconds.
7. Register the IDs in order from FR LH, FR RH, RR RH or RR LH. When ID registration of each wheel has been completed, a buzzer sounds and turn signal lamp (LH/ RH) blinks.
8. 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.

5. Select “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.
6. 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 a few minutes.
7. After completing all ID registrations, press “END” to complete the procedure.
8. Inflate all tires to proper pressure. Refer to WT-37, "

Transmitter Wake Up OperationAES000Z6
WITH ACTIVATION TOOL
1. With the 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 warning lamp flashes. When wake up of registered wheel has been com- pleted, turn signal lamp flashes two times.
3. After completing wake up all transmitters, make sure low tire pressure warning lamp goes out.

Self-DiagnosisAES000Z7
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 judgement 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.
