After Front Wipers Operate for 10 Seconds, They Stop for 20 Seconds, and after
repeating the operations five times, they become inoperative

AKS00AN6

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”.

CHECK WIPER MOTOR SIGNAL

With CONSULT-ll

Select “IPDM E/R” on CONSULT-II. With “DATA MONITOR”, confirm
that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with wiper
operation.

Lift the blade up and then set it down onto glass surface to set
the blade center to clearance “L1” & “L2” immediately before
tightening nut.

Eject washer fluid. Turn on wiper switch to operate wiper motor
and then turn it “OFF”.

Ensure that wiper blades stop within clearance “L1” & “L2”.

●

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 “A” and “B” as shown in the figure.
(See the illustration)

●

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.

Unit: mm (in)

CAUTION:

Do not adjust the washer nozzle with needle pin. If attempts are
made to adjust the washer nozzle with needle pin, damage may
occur.
