DISPLAY UNIT
Display the air pressure of each tire.

After the ignition switch is turned ON, the pressure values are
not be displayed until the data of wheels stabilizes.
Can CommunicationNES000KV
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
For details, refer to LAN-50, "
CAN System Specification Chart" .

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-diagnosis results
display will not function properly.
ID REGISTRATION WITHOUT ACTIVATION TOOL
This procedure must be done after replacement of a tire pressure transmitter, low tire pressure warn-
ing control unit, or tire rotation.
1. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
2. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
3. Touch “ID REGIST” on “SELECT WORK ITEM”.
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 a few minutes.
5. After completing all ID registrations, press “END” to complete the procedure.
6. Inflate all tires to proper pressure. Refer to WT-41, "
SERVICE DATA AND SPECIFICATIONS (SDS)" .

Transmitter Wake Up OperationNES000JZ
WITH TRANSMITTER ACTIVATION TOOL
1. With the activation tool (J-45295) pushed against the front-left
transmitter, press and hold the button for 5 seconds.

When ignition switch ON, as the low tire pressure warning
lamp blinks per the follow diagram, the respective transmitter
then must be wake 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.

Diagnosis Procedure with Warning Lamp Function (Without CONSULT-II)NES000K6
DESCRIPTION
During driving, the tire pressure monitoring system receives the signal transmitted from the transmitter
installed in each wheel when the tire pressure becomes low. The control unit (low tire pressure warning control
unit) of this system has pressure judgement and trouble diagnosis functions.
FUNCTION
When the tire pressure monitoring 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. Regarding location of tire pressure warning check connector, refer to PG-62, "
HARNESS" .

TROUBLE DIAGNOSIS FOR SYSTEMPFP:00000
Transmitter no DataNES000KA
MALFUNCTION CODE NO. 21, 22, 23, 24
1. CHECK CONTROL UNIT
Drive for several minutes. Check all tire pressures with CONSULT-II “DATA MONITOR”.
Are all tire pressures displayed 0 kPa?
YES >> GO TO 2.
NO >> GO TO 3.
2. CHECK TIRE PRESSURE RECEIVER CONNECTOR
1. Disconnect tire pressure receiver harness connector E74 (FR-LH), E75 (FR-RH), B482 (RR-RH), B115
(RR-LH).
2. Check terminals for damage or loose connection.
3. Reconnect harness connector.
OK or NG
OK >> Replace low tire pressure warning control unit. Refer to WT-40, "Low Tire Pressure Warning Con-
trol Unit" , then GO TO 3.
NG >> Repair or replace tire pressure receiver harness connector.
3. ID REGISTRATION
Perform ID registration of all transmitters.
Are there any tires that ID can not be registered to?
YES >> Replace transmitter of the tire, then GO TO 5.
NO >> GO TO 4.
4. VEHICLE DRIVING
Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping.
Check all tire pressures with CONSULT-II “DATA MONITOR” within 15 minutes after vehicle speed becomes
17 km/h (11 MPH).
Does
“DATA MONITOR ” display tire pressure as normal without any warning lamp?
YES >>INSPECTION END
NO >> GO TO 5.
5. ID REGISTRATION AND VEHICLE DRIVING
1. Perform ID registration of all transmitters.
2. Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for
10 minutes. Then check all tire pressures with CONSULT-II “DATA MONITOR” within 5 minutes.
Does
“DATA MONITOR” display tire pressure as normal without any warning lamp?
YES >>INSPECTION END
NO >> GO TO the inspection applicable to DTC.
