Front Wiper Does Not Return to Stop Position (After Front Wipers Operate for
10 Seconds, They Stop for 20 Seconds, and after repeating the operations five
times, they become inoperative)
BKS001TS
CAUTION:

When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers that front wipers are locked, and stops front wiper output. That
causes this symptom.

This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIP PROT” item shows
“BLOCK”.
1. CHECK BCM DATA MONITOR
With CONSULT-II
1. Select “BCM” on CONSULT-II, and select “WIPER” on “SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
Make sure that “FR WIPER STOP” turns ON-OFF according to
front wiper operation.
Without CONSULT-II
GO TO 2.
OK or NG
OK >> Replace IPDM E/R. Refer to PG-28, "Removal and
Installation of IPDM E/R" .
NG >> GO TO 2.
2. CHECK CIRCUIT BETWEEN IPDM E/R AND FRONT WIPER MOTOR
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connector.
3. Check continuity between IPDM E/R harness connector (A) and
front wiper motor harness connector (B).
4. Check continuity between IPDM E/R harness connector (A) and
ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.When front wiper is operating :FR WIPER STOP OFF

HEADLAMP WASHER

HEADLAMP WASHERPFP:28620
Components Parts and Harness Connector LocationBKS002CB
System DescriptionBKS002CC

BCM (Body Control Module) controls headlamp washer operation.

IPDM E/R (Intelligent Power Distribution Module Engine Room) operates headlamp washer pump accord-
ing to CAN communication signal from BCM.
OUTLINE
Power is supplied at all times

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

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

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

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

to CPU in IPDM E/R,

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

to BCM terminal 55,

through 30A fusible link (letter J, located in fuse and fusible link block)

to headlamp washer relay terminals 1 and 3.
With the ignition switch in the ON or START position, power is supplied

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

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

to BCM terminal 38.
With the ignition switch in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to BCM terminal 11.
Ground is supplied

to BCM terminal 52

through grounds M71 and M72,

to IPDM E/R terminals 38 and 60

When the headlamp washer switch is ON, ground is supplied

to BCM terminal 10

through headlamp washer switch terminal 1

through headlamp washer switch terminal 2

through grounds M71 and M72.
HEADLAMP WASHER OPERATION
When the headlamp washer switch is in ON position with the ignition switch in ON position and the lighting
switch in 2ND position, BCM detects the headlamp washer switch ON signal. It also detects the HEAD LAMP1
and 2 (ON) by BCM combination switch reading function. BCM judges that the condition of headlamp washer
operation meets. And then, BCM sends headlamp washer request signal (ON) through CAN communication.
When receiving headlamp washer request signal (ON), IPDM E/R turns ON headlamp washer relay. And then,
headlamp washer pump operates.
Power is supplied

through headlamp washer relay terminal 2

to IPDM E/R terminal 58,

through headlamp washer relay terminal 5

to headlamp washer pump terminal 1.
Ground is supplied

to headlamp washer pump terminal 2

through grounds E1 and E31.
With power and ground supplied, headlamp washer operates.
INTERLOCKED OPERATION WITH FRONT WINDOW WASHER
When the front window washer switch is in ON position at the every first time of ignition switch ON, with the
ignition switch in ON position and the lighting switch in 2ND position, BCM detects the FR WASHER (ON) and
the HEAD LAMP 1 and 2 (ON) by BCM combination switch reading function. BCM judges that the condition of
headlamp washer operation meets. And then, BCM sends headlamp washer request signal (ON) through
CAN communication.
When receiving headlamp washer request signal (ON), IPDM E/R turns ON headlamp washer relay. And then,
headlamp washer pump operates.
COMBINATION SWITCH READING FUNCTION
Refer to WW-7, "COMBINATION SWITCH READING FUNCTION" .
