Front Wiper Does Not Return to Stop Position When Front Wiper Motor Oper-
ates at Low Speed (After Front Wiper Operate for 10 Seconds, They Stop for 20
Seconds, and After Repeating the Operations Five Times, They Become Inoper-
ative)
NKS003WP
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 FRONT WIPER STOP SIGNAL
With CONSULT-II
Select “IPDM E/R” on CONSULT-II. With “DATA MONITOR”, make
sure that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with
wiper LO operation.
Without CONSULT-II
GO TO 2.
OK or NG
OK >> Replace IPDM E/R. Refer to PG-31, "Removal and
Installation of IPDM E/R" .
NG >> GO TO 2.
2. CHECK IPDM E/R
Check voltage between IPDM E/R harness connector and ground
while front wiper motor is stopped and while front wiper LO is operat-
ing.
OK or NG
OK >> Replace IPDM E/R. Refer to PG-31, "Removal and Installation of IPDM E/R" .
NG >> GO TO 3.
3. CHECK CIRCUIT BETWEEN FRONT WIPER MOTOR AND GROUND
1. Turn ignition switch OFF.
2. Disconnect front wiper motor connector.
3. Check continuity between front wiper motor harness connector
E27 terminal 6 and ground.
OK or NG
OK >> Replace front wiper motor. Refer to WW-43, "Disassem-
bly and Assembly of Front Wiper Drive Assembly" .
NG >> Repair harness or connector.
