FRONT WIPERS OPERATE FOR 10 SECONDS, STOP FOR 20 SECONDS, AND AFTER
REPEATING THIS OPERATION FIVE TIMES, THEY BECOME INOPERATIVE
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 front wipers locked and stops wiper output, which causes this symp-
tom.
This status can be checked by using IPDM E/R "DATA MONITOR". Under this condition, "WIP
PROT" reads "BLOCK".
Inspection Procedure
1. IPDM E/R TO FRONT WIPER MOTOR (1) INSPECTION
With CONSULT-II
Select "IPDM E/R" with CONSULT-II. With data monitor, confirm that
"WIP AUTO STOP" changes from "ACT P" to "STOP P" according to
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. Remove the wiper arm mounting covers.
3. Remove the wiper arm mounting nuts, then remove the wiper arms.
INSTALLATION
1. Prior to wiper arm installation, turn on wiper switch to operate
wiper motor and then turn it "OFF" (Auto Stop).
2. Lift the blade up and then set it down onto glass surface to set
