PRECAUTIONS
Before replacing BCM, perform c ontrol unit input/output sig-
nal inspection and make sure whether BCM functions prop-
erly or not. Refer to WT-17, "
Control Unit Input/Output Signal
Standard".

 Low tire pressure warning lamp flashes 1min, then turns ON when occurring any malfunction except low tire
pressure. Delete the memory with CONSULT-III, or regi ster the ID to turn low tire pressure warning lamp
OFF. Refer to WT-22, "
CONSULT-III Function (BCM)", WT-19, "ID Registration Procedure".
 ID registration is required when replacing or rotati ng wheels, replacing transmitter or BCM. Refer to WT-19,
"ID Registration Procedure".
 Replace grommet seal, valve core and cap of the transmi tter in TPMS every tire replacement by reaching
wear limit of tire.

The BCM reads the air pressure signal received by the remote key-
less entry receiver, and controls the low tire pressure warning lamp
and the buzzer operations. It also has a judgment function to detect
a system malfunction.
LOW TIRE PRESSURE WARNING LAMP
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter low tire pressure warn-
ing lamp is activated.
Low Tire pressure Warning Lamp Indication
Note 1: Standard air pressure is for 220 kpa (2.2 kg/cm2, 32 psi) vehicles.
RUN-FLAT TIRE WARNING LAMP
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter run-frat tire warning
lamp and buzzer are activated.

ID Registration ProcedureINFOID:0000000001327582
ID REGISTRATION WITH ACTIVATION TOOL
This procedure must be done after replacemen t of a transmitter, BCM or rotating wheels.
1. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.
2. With the transmitter activati on tool (J-45295) pushed against the
front-left transmitter position of the air valve, press and hold the
button 5 seconds.
3. 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.
4. 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.
ID Registration without Tr ansmitter Activation Tool
CAUTION:
This procedure must be done after replacement of a transmitter, BCM, or rotating wheels.
1. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.
2. Adjust the tire pressure to the values shown in t he 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.
3. After completing all ID registrations, press “END” to complete the procedure.

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 warninglamp 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-DiagnosisINFOID:0000000001327584
DESCRIPTION
During driving, the low tire pressure warning syste m 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 malf unction location is indicated by the warning lamp flash-
ing and the buzzer sounds.
