Transmitter Wake Up Operation

NES000JZ

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"

.
