ID Registration ProcedureNES000JY
ID REGISTRATION WITH ACTIVATION TOOL
This procedure must be done after replacement of a tire pressure transmitter, low tire pressure warn-
ing control unit, or tire rotation.
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. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL)” “AIR PRESSURE MONITOR”.
If “AIR PRESSURE MONITOR” is not displayed, print the “SELECT SYSTEM” screen. Then refer to
LAN-7, "
Precautions When Using CONSULT-II"
NOTE:
Just after starting engine, or turning ignition switch ON, it may not be displayed even if “START (NIS-
SAN BASED VHCL)” is touched. In this case, reconnect CONSULT-II and CONSULT-II CONVERTER.
5. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
6. Touch “ID REGIST” on “SELECT WORK ITEM”.
7. With the activation tool [SST: J-45295] pushed against the front-
left tire pressure transmitter position of the tire air valve, press
and hold the button for 5 seconds.
8. Register the IDs in order from FR LH, FR RH, RR RH, RR LH.
When ID registration of each wheel has been completed, a
buzzer sounds and turn signal lamp blinks.
9. 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-diagnosis results
display will not function properly.
