OK or NG
OK >> Replace front wiper motor.
NG >> Replace IPDM E/R.
Only Front Wiper Intermittent Does Not OperateNKS0032M
1. CHECK COMBINATION SWITCH
With CONSULT-ll
1. Select “BCM” on CONSULT-II, and select “WIPER” on “SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen. Make sure that “FR WIPER INT”, turn ON-OFF according to

After Front Wiper Operate for 10 Seconds, They Stop for 20 Seconds, and After
Repeating the Operations Five Times, They Become Inoperative
NKS0032Q
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
With CONSULT-ll
Select “IPDM E/R” by CONSULT-II. With “DATA MONITOR”, make
sure that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with
wiper operation.
Without CONSULT-ll
GO TO 2.
OK or NG
OK >> Replace 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 E7 ter- minal 32 and front wiper motor harness connector E57 terminal
5.
4. Check continuity between IPDM E/R harness connector E7 ter- minal 32 and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3. CHECK FRONT WIPER MOTOR
1. Connect IPDM E/R connector and front wiper connector.
2. Turn ignition switch ON.
3. Check voltage between IPDM E/R harness connector E7 termi- nal 32 and ground while front wiper motor is stopped and while it
is operating.
OK or NG
OK >> Replace IPDM E/R.
NG >> Replace front wiper motor.
