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" .

Components Parts and Harness Connector LocationNKS003WB
System DescriptionNKS003WC

Front wiper relays (HIGH, LOW) are included in IPDM E/R (intelligent power distribution module engine
room).

Front wiper reverse relay is included in relay box-1. Refer to PG-98, "ELECTRICAL UNITS LOCATION" .

Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. Terminal combination status is read by BCM (body control module) when switch is turned ON.

BCM controls front wiper LO, HI, and INT (intermittent) operation.

IPDM E/R operates wiper motor according to CAN communication signals from BCM.

Front wiper motor switches LOW speed to/from HIGH speed by BCM function to change polarity.

Power is supplied at all times

to ignition relay, located in IPDM E/R, from battery directly,

through 50 A fusible link (letter F, located in fuse and fusible link block)

to BCM terminal 55,

through 10 A fuse [No. 21, located in fuse block (J/B)]

through 15 A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38,

through 10 A fuse [No. 12, located in fuse block (J/B)]

through grounds M16 and M70,

to IPDM E/R terminals 38 and 51

through grounds E22 and E43,

to combination switch terminal 12

through grounds M16 and M70.
LOW SPEED WIPER OPERATION
When wiper switch is in the LO position, BCM detects low speed wiper ON signal by BCM wiper switch read-
ing function.
BCM sends front wiper request signal (LO) with CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 49 and 50.
When IPDM E/R receives front wiper request signal (LO), it turns ON front wiper low relay, located in IPDM
E/R, power is supplied

through IPDM E/R terminal 23 and front wiper high relay and front wiper low relay

to front wiper motor terminal 3.
Ground is supplied

to front wiper motor terminal 1

through front wiper reverse relay terminals 3 and 4

through grounds E22 and E43.
With power and ground supplied, the front wiper motor operates at low speed.

FRONT WIPER AND WASHER SYSTEM
Revision: 2007 April2007 M35/M45
HIGH SPEED WIPER OPERATION
When wiper switch is in the HI position, BCM detects high speed wiper ON signal by BCM wiper switch read-
ing function.
BCM sends front wiper request signal (HI) with CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 49 and 50.
When IPDM E/R receives front wiper request signal (HI), it turns ON front wiper high relay (located in IPDM
E/R) and front wiper reverse relay (located in relay box-1), power is supplied

through IPDM E/R terminal 19

through front wiper reverse relay terminals 5 and 3

to front wiper motor terminal 1.
Ground is supplied

to front wiper motor terminal 2

to IPDM E/R terminal 31 and front wiper high relay and front wiper low relay

to IPDM E/R terminal 38

through grounds E22 and E43.
With power and ground supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
1. BCM detects ON/OFF status of intermittent operation dial position 1, 2 and 3 switched by wiper dial posi-
tion to judge wiper dial position status.
2. BCM calculates intermittent operation interval time (second) from the vehicle speed signal received by
combination meter through CAN communication line and the wiper dial position.
Unit: second
NOTE:
The value in the table can differ from the actual vehicle speed.
3. BCM switches front wiper request signal transmitted to IPDM E/R through CAN communication line from
STOP to LO once at intervals of intermittent operation time.
4. IPDM E/R receives front wiper request signal (LO) once to turn ON front wiper main relay located in IPDM
E/R. Then operates front wiper. IPDM E/R receives front wiper auto stop signal (stop) input from front
wiper motor to turn OFF front wiper motor relay. IPDM E/R switches front wiper auto stop signal transmit-
ted through CAN communication line from MOVE to STOP.
5. BCM receives front wiper auto stop signal (stop) to operate timer that determines intermittent operation
interval time till next front wiper motor operation.
