After Front Wiper Operate for 10 Seconds, They Stop for 20 Seconds, and After
Repeating the Operations Five Times, They Become Inoperative
NKS0052J
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 WIPER MOTOR SIGNAL
CONSULT-III DATA MONITOR
1. Select "WIP AUTO STOP" of BCM data monitor item.
2. make sure that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with wiper operation.

OK or NG
OK >> Replace IPDM E/R. Refer to PG-26, "Removal and Installation of IPDM E/R" .
NG >> GO TO 2.
2. CHECK WIPER AUTO STOP CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connec-
tor.
3. Check continuity between IPDM E/R harness connector (A) and
front wiper motor harness connector (B).
4. Check continuity between IPDM E/R harness connector (A) and
ground.
