After Front Wiper Operate for 10 Seconds, They Stop for 20 Seconds, and After
Repeating the Operations Five Times, They Become Inoperative
AKS00CRS
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 wiper output. That causes this
symptom.
●
This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
item shows “BLOCK”.
1.
CHECK WIPER MOTOR SIGNAL
With CONSULT-ll
Select “IPDM E/R” by CONSULT-II. With “DATA MONITOR”, make
sure that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with
wiper operation.
Without CONSULT-ll

CHECK WIPER AUTO STOP CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect IPDM E/R connector and front wiper motor connec-
tor.
3.
Check continuity between IPDM E/R harness connector E7 ter-
minal 32 (L/Y) and front wiper motor harness connector E22 ter-
minal 4 (L/Y).
4.
Check continuity between IPDM E/R harness connector E7 ter-
minal 32 (L/Y) and ground.

Washer Nozzle Adjustment
AKS00ANB
●
In this model, the washer nozzle has a non-adjustment nozzle and requires no adjusting.
●
If necessary, ensure that washer fluid spray covers at least the area as shown in the figure. (See the illus-
tration)
●
If the above is not satisfied, confirm that the washer nozzle is installed correctly on the cowl top cover and/
or cowl top cover is installed correctly on the body.
●
If they are installed correctly, and the fluid is still spraying out of the shooting target areas, replace them
with new washer nozzle and/or cowl top cover.
CAUTION:
Never adjust the washer nozzle with needle pin. If attempts are
made to adjust the washer nozzle with needle pin, damage may
occur.

System Description
AKS004X4
●
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 (body control module) controls rear wiper ON and INT (intermittent) operation.

through 10 A fuse [No. 18, located in fuse block (J/B)]
●
to BCM terminal 42.
When ignition switch ON or START position, power is supplied
●
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 (intelligent power distribution module engine room)]

REAR WIPER OPERATION
When wiper switch is in rear wiper ON position, BCM detect rear wiper ON signal by BCM wiper switch read-
ing function.
When BCM operates rear wiper motor, power is supplied
●
through BCM terminal 70
●
to rear wiper motor 4.
Ground is supplied
●
to rear wiper motor terminal 2
●
through grounds B7 and B20.
With power and ground supplied, the rear wiper operates.
INTERMITTENT OPERATION
The rear wiper motor operates the wiper arms at low speed approximately every 7 seconds.
When wiper switch is in rear wiper INT position, BCM detects rear wiper INT signal by BCM wiper switch read-
ing function (Refer to
WW-7, "COMBINATION SWITCH READING FUNCTION"
When BCM operates rear wiper motor, power supplied
●
through BCM terminal 70
●
to rear wiper motor 4.
Ground is supplied
●
to rear wiper motor terminal 2
●
through grounds B7 and B20.
With power and ground supplied, rear wiper operates at intermittent.
AUTO STOP OPERATION
With rear wiper switch turned OFF, rear wiper motor will continue to operate until wiper arm reaches rear wiper
stopper.
Then wiper motor turns the other way and wiper arm moves once until wiper arm reaches stopper.
WASHER OPERATION
When wiper switch is in rear wiper washer position, BCM detects rear wiper washer signal by BCM wiper
switch reading function (Refer to
WW-7, "COMBINATION SWITCH READING FUNCTION"
), and combination
switch (wiper switch) power is supplied
●
through combination switch terminal 11
●
to front and rear washer motor terminal 2.
Ground is supplied
●
to front and rear washer motor terminal 1
●
through combination switch terminal 13
●
to combination switch terminal 12
●
through grounds M14 and M78.
With ground supplied, front and rear washer motor is operated.
When BCM detects that front and rear washer motor has operated for 0.4 seconds or longer, BCM operates
rear wiper motor at low speed.
When BCM detects washer switch is OFF, low speed operation cycles approximately 3 times and then stops.
