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”.

●
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
