CAUTION:

Do not use electrical test equipment on any circuit related to the SRS unless instructed to do so in
this Service Manual.

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

Keep ground connections 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

FRONT WIPER AND WASHER SYSTEM

FRONT WIPER AND WASHER SYSTEMPFP:28810
Components Parts and Harness Connector LocationEKS00I1G
System DescriptionEKS00I1H

Front wiper relays (front wiper relay, front wiper high relay) are located in the IPDM E/R (intelligent power
distribution module engine room).

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.
OUTLINE
Power is supplied at all times

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

through 40A fusible link (letter g, located in fuse, fusible link and relay box)

to BCM terminal 70,

through 30A fuse (No. 39, located in IPDM E/R)

to front wiper relay located in IPDM E/R

through 15A fuse (No. 52, located in IPDM E/R), and

through 20A fuse (No. 53, located in IPDM E/R)

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

through ignition relay (located in IPDM E/R)

to front wiper motor terminal 2

through grounds E15 and E24,

to BCM terminal 67

to combination switch terminal 12

through grounds M57 and M61.
LOW SPEED WIPER OPERATION
When the front wiper switch is in LO position, the BCM detects the low speed wiper ON signal by means of the
BCM wiper switch reading function.
The BCM sends a front wiper request signal (LO) through the CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 40 and 41.
When the IPDM E/R receives front wiper request signal (LO), it turns ON front wiper relay, located in IPDM E/
R, power is supplied

through IPDM E/R terminal 33 and front wiper high relay and front wiper relay

to front wiper motor terminal 3.
Ground is supplied

to front wiper motor terminal 2

through grounds E15 and E24.
With power and ground is supplied, front wiper motor operates at low speed.
HIGH SPEED WIPER OPERATION
When the front wiper switch is in HI position, the BCM detects a high speed wiper ON signal by means of the
BCM wiper switch reading function.
The BCM sends a front wiper request signal (HI) through the CAN communication line

from BCM terminals 39 and 40

to IPDM E/R terminals 40 and 41.
When the IPDM E/R receives front wiper request signal (HI), it turns ON front wiper relay and front wiper high
relay, located in IPDM E/R, power is supplied

through IPDM E/R terminal 32

to front wiper motor terminal 5.
Ground is supplied

to front wiper motor terminal 2

through grounds E15 and E24.
With power and ground is supplied, front wiper motor operates at high speed.
INTERMITTENT OPERATION
Wiper intermittent operation delay interval is determined from the intermittent wiper dial position inputs. During
each intermittent operation delay interval, the BCM sends a front wiper request signal to the IPDM E/R to
operate the wipers.
When the ignition switch is in the ON or START position, and the front wiper switch is turned to the intermittent
position, the BCM detects a front wiper (intermittent) ON signal by means of the BCM wiper switch reading
function.
BCM then sends front wiper (intermittent) request signal through the CAN communication lines

REAR WIPER OPERATION
When the ignition switch is in the ON or START position, and the rear wiper switch is in the ON position, the
BCM detects a rear wiper ON request through the combination switch (wiper switch) reading function and con-
trols the rear wiper motor as follows.
Power is supplied

through BCM terminal 55

to rear wiper motor terminal 1.
Ground is supplied

to rear wiper motor terminal 3

through grounds B117, B132 and D402.
With power and ground supplied, the rear wiper motor operates.
INTERMITTENT OPERATION
The rear wiper motor operates the wiper arm at low speed approximately every 7 seconds.
When the wiper switch is in the rear wiper INT position, the BCM detects a rear wiper INT request through the
combination switch (wiper switch) reading function.
When BCM operates rear wiper motor, power is supplied

through BCM terminal 55

to rear wiper motor terminal 1.
Ground is supplied

to rear wiper motor terminal 3

through grounds B117, B132 and D402.
With power and ground supplied, the rear wiper operates in intermittent mode.
AUTO STOP OPERATION
When the rear wiper arm is not located at the base of the rear window, and the rear wiper switch is turned
OFF, the rear wiper motor will continue to operate until the rear wiper arm is at the base of the rear window.
When the rear wiper arm reaches the base, rear wiper motor terminals 2 and 1 are connected.
Ground is supplied

to BCM terminal 44

through rear wiper motor terminal 2

through rear wiper motor terminal 3

through grounds B117, B132 and D402.
REAR WASHER OPERATION
When the ignition switch is in the ON or START position, and the front and rear washer switches are OFF, the
front and rear washer motor is supplied power

through 15A fuse [No. 4, located in the fuse block (J/B)]

to combination switch (wiper switch) terminal 14

through combination switch (wiper switch) terminal 11

to front and rear washer motor terminal 2.
When the rear wiper switch is in rear washer position, the BCM detects a rear washer signal by BCM wiper
switch reading function. Combination switch ground is supplied

to front and rear washer motor terminal 1

through combination switch (wiper switch) terminal 13

through combination switch (wiper switch) terminal 12

through grounds M57 and M61.
With ground supplied, the front and rear washer motor is operated in the rear direction.
When the BCM detects that the rear washer motor has operated for 0.4 seconds or longer, BCM operates the
rear wiper motor.
When the BCM detects that the rear washer switch is in OFF, the rear wiper motor cycles approximately 3
times and then stops.
If the rear washer is operated with the rear wiper switch in the INT position, normal rear wiper operation will
take over. Once the rear washer switch is released the rear wiper will return to INT operation.
