After Front Wiper Operate for 10 Seconds, They Stop for 20 Seconds, and after 
Repeating the Operations Five Times, They Become Inoperative

NKS001UA

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”.

●

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
