LOW TIRE PRESSURE WARNING CONTROL UNIT PART NUMBER
Operation Procedure
1. Perform “CONSULT-II Start Procedure”. Refer to GI-39, "CONSULT-II Start Procedure" .
2. The part number described on low tire pressure warning control unit sticker is displayed.
Diagnosis Procedure with Warning Lamp Function (Without CONSULT-II)NES000K6
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (low tire pres-
sure warning control unit) of this system has pressure judgement 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 malfunction location is indicated by the warning lamp flash-
ing and the buzzer sounds. Regarding location of tire pressure warning check connector, refer to PG-63,
"HARNESS" .

FRONT WIPER AND WASHER SYSTEMPFP:28810
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-96, "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.

With the ignition switch in the ON or START position, power is supplied
to ignition relay, located in IPDM E/R,
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)]

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.

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.

AUTO STOP OPERATION
With wiper switch turned OFF, wiper motor will continue to operate until wiper arms reach windshield base.
When wiper arms are not located at base of windshield with wiper switch OFF, ground is provided
from IPDM E/R terminal 23
to front wiper motor terminal 3, in order to continue wiper motor operation at low speed.
When wiper arms reach base of windshield, front wiper motor terminals 4 and 5 are connected
to IPDM E/R terminal 32
through front wiper motor terminals 4 and 5.
Then the IPDM E/R sends auto stop operation signal to BCM with CAN communication line.
When BCM receives auto stop operation signal, BCM sends wiper stop signal to IPDM E/R with CAN commu-
nication line.
IPDM E/R stops wiper motor. Wiper motor will then stop wiper arms at the STOP position.
WAS H ER O P E R ATI O N
When wiper switch is in front wiper washer position with ignition switch ON, BCM detects front wiper washer
signal by BCM wiper switch reading function (refer to BCS-3, "
COMBINATION SWITCH READING FUNC-
TION" ). Combination switch ground is supplied
to front washer motor terminal 2
through combination switch terminal 14
to combination switch terminal 12
through grounds M16 and M70.
And power is supplied
through combination switch terminal 13
to front washer motor terminal 1.
With power and ground supplied, front washer motor is operated.
When BCM detects that front washer motor has operated for 0.4 seconds or longer, BCM operates front wiper
motor for low speed.
When BCM detects washer switch is OFF, low speed operation cycles approximately 2 times and stops.
MIST OPERATION
When the wiper switch is turned to the MIST position, wiper low speed operation cycles once and then stops.
For additional information about wiper operation under this condition, refer to WW-5, "
LOW SPEED WIPER
OPERATION" .
If the switch is held in the MIST position, low speed operation continues.
FAIL-SAFE FUNCTION
If an abnormality occurs in CAN communications, IPDM E/R holds the condition just before fail-safe status is
initiated until ignition switch is turned OFF. (If wipers were operating in LO just before the initiation of fail-safe
status, they continue to operate in LOW until ignition switch is turned OFF.)
