System Description
EES001BE
TRANSMITTER
A sensor-transmitter integrated with a valve is installed on a wheel,
and transmits a detected air pressure signal in the form of a radio
wave.
REMOTE KEYLESS ENTRY RECEIVER
Receives the air pressure signal transmitted by the transmitter in
each wheel.

LOW TIRE PRESSURE WARNING SYSTEM
2005 Pathfinder
BCM (BODY CONTROL MODULE)
Reads the air pressure signal received by the remote keyless entry
receiver, and controls the warning lamp and the buzzer operations
as shown below. It also has a judgement function to detect a system
malfunction.
WARNING LAMP AND BUZZER
Indicates low tire pressure or system malfunction.
DISPLAY UNIT (WITH NAVI)
Displays the air pressure of each tire.
●
After the ignition switch is turned on, the pressure values are not
displayed until the data of each wheel is received.

ID Registration Procedure
EES001BI
ID REGISTRATION WITH TRANSMITTER ACTIVATION TOOL
This procedure must be done after replacement of a low tire pressure warning 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 carry out 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.
Touch “BCM” on "SELECT SYSTEM" screen.
NOTE:
If "BCM" is not indicated, go to
.
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 transmitter activation tool (J-45295) pushed against the
front left transmitter position of the tire air valve, press the button
for 5 seconds.
7.
Register the IDs in order from FR LH, FR RH, RR RH and RR LH. When ID registration of each wheel has
been completed, a buzzer sounds and the warning lamp flashes.
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.
