Removal and InstallationBIS0014E
REMOVAL
CAUTION:

Before removing the front seat, turn the ignition switch off, disconnect both battery cables and
wait and least 3 minutes.

When checking the power seat circuit for continuity using a circuit tester, do not confuse its con-
nector with the side air bag module connector. Such an error may cause the air bag to deploy.

Do not drop, tilt, or bump the side air bag module installing in the seat. Always handle it with care.
1. Remove front leg cover and rear leg cover (LH/RH).
2. Remove bolts.
NOTE:
Set seat sliding and seat reclining to center position when disassembling power seat after removing bolts.
Set seat lifter to top position when disassembling.
3. Disconnect side air bag module connector and power seat harness connector under the seat and remove
harness securing clips.
CAUTION:
Before removal, be sure to turn ignition switch OFF, disconnect both battery cables, and then wait
for at least 3 minutes.
4. Remove seat from the vehicle.
CAUTION:
When removing and installing, use shop cloths to protect parts from damage.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
Before installation, be sure to turn ignition switch OFF, disconnect both battery cables, and then wait
for at least 3 minutes.

TROUBLE DIAGNOSISPFP:00004
Trouble Diagnosis IntroductionBHS00043
CAUTION:

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.

Keep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function through the operation of the “AIR BAG” warning lamp.
The Diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the “AIR BAG” warning lamp and CONSULT-II are as follows:
HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.

POWER SUPPLY ROUTING CIRCUIT" .
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. CHECK AIR BAG FUSE AGAIN
Replace “AIR BAG” fuse and turn ignition switch ON.
Does the
“AIR BAG” fuse blow again?
YES >> Repair or replace main harness.
NO >>INSPECTION END
4. CHECK DIAGNOSIS SENSOR UNIT
Connect CONSULT-II and touch “START”.
Is
“AIR BAG” displayed on CONSULT-ll?
YES >> GO TO 5.
NO >> Visually check the wiring harness connection of diagno-
sis sensor unit. If the harness connection check result is
OK, replace diagnosis sensor unit.
5. CHECK HARNESS CONNECTION
Is harness connection between warning lamp and diagnosis sensor unit OK?
OK or NG
OK >> Replace diagnosis sensor unit.
NG >> Connect “AIR BAG” warning lamp and diagnosis sensor unit connector properly. If “AIR BAG”
warning lamp still does not go off, replace harness.

FRONT WIPER AND WASHER SYSTEM

FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationBKS001TF
System DescriptionBKS001TG

BCM (Body Control Module) controls front wiper low, high and intermittent operation.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates front wiper motor according to
CAN communication signals from BCM.
Power is supplied at all times

to ignition relay (located in IPDM E/R), from battery direct,

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

to BCM terminal 55,

through 15 A fuse [No. 17, located in fuse block (J/B)]

to BCM terminal 42,

through 20 A fuse (No. 73, located in IPDM E/R)

to front wiper relay (located in IPDM E/R),

through 15 A fuse (No. 78, located in IPDM E/R)

to CPU (central processing unit) located in IPDM E/R,

through 15 A fuse (No. 71, located in IPDM E/R)

to CPU located in IPDM E/R.
When the ignition switch ON or START position, power is supplied

to ignition relay (located in IPDM E/R),

through 10 A fuse [No. 1, located in fuse block (J/B)]

to BCM terminal 38,

through 10 A fuse (No. 84, located in IPDM E/R)

to front washer pump terminal 1.
Ground is supplied

to BCM terminal 52 and

to combination switch terminal 12

through grounds M71 and M72,

to IPDM E/R terminals 38 and 60

through grounds E1 and E31.
LOW SPEED WIPER OPERATION
When the front wiper switch is in LO position, BCM detects the FR WIPER LOW (ON) by BCM combination
switch reading function. BCM sends front wiper request signal (LO) through CAN communication.
When receiving front wiper request signal (LO), IPDM E/R turns ON front wiper relay in IPDM E/R. IPDM E/R
supplies power

through IPDM E/R terminal 21, front wiper high relay and front wiper relay

to front wiper motor terminal 1.
Ground is supplied

to front wiper motor terminal 2

through grounds E1 and E31.
With power and ground is supplied, the front wiper motor operates at low speed.
HIGH SPEED WIPER OPERATION
When the front wiper switch is in HI position, BCM detects the FR WIPER HI (HI) by BCM combination switch
reading function. BCM sends front wiper request signal (HI) through CAN communication.
When receiving front wiper request signal (HI), IPDM E/R turns ON front wiper relay and front wiper high relay
in IPDM E/R. IPDM E/R supplies power

through IPDM E/R terminal 31, front wiper high relay and front wiper relay

to front wiper motor terminal 4.
Ground is supplied

to front wiper motor terminal 2

through grounds E1 and E31.
With power and ground is supplied, the front wiper motor operates at high speed.
INTERMITTENT OPERATION
Front wiper intermittent operation is determined from a combination of 3 switches (INT VOLUME 1, 2, and 3)
and vehicle speed signal*.
When the front wiper switch is in INT position, BCM detects the FR WIPER INT (ON) and ON/OFF status of
the INT VOLUME 1, 2, and 3 by BCM combination switch reading function. BCM judges the condition of wiper
intermittent dial position by ON/OFF status of INT VOLUME 1, 2, and 3 .
BCM sends front wiper request signal (1LOW) at certain intervals through CAN communication. The interval is
calculated by wiper intermittent dial position and vehicle speed signal received from combination meter
through CAN communication.
When receiving front wiper request signal (1LOW), IPDM E/R turns ON front wiper relay in IPDM E/R, and
operates front wiper motor at low speed. Then IPDM E/R detects front wiper arms reach to the stop position
via wiper auto stop signal from front wiper motor, IPDM E/R turns OFF front wiper relay, and sends front wiper
auto stop signal (ON) to BCM through CAN communication, and controls intermittent operation.
