7. CHECK IPDM E/R
With CONSULT-II
1. Connect IPDM E/R connector and front wiper motor connector.
2. Install front wiper reverse relay.
3. Select “IPDM E/R” on CONSULT-II. Select “ACTIVE TEST” on “SELECT DIAG MODE” screen.
4. Select “FRONT WIPER” on “SELECT TEST ITEM” screen.
5. Touch “LO” or “HI” screen.
6. Check voltage between IPDM E/R harness connector and
ground while front wiper (HI, LO) is operating.
Without CONSULT-II
1. Connect IPDM E/R connector and front wiper motor connector.
2. Install front wiper reverse relay.
3. Start up auto active test. Refer to PG-23, "
Auto Active Test" .
4. Check voltage between IPDM E/R harness connector and ground while front wiper (HI, LO) is operating.
OK or NG
OK >> Replace front wiper motor. Refer to WW-44, "Disassembly and Assembly of Front Wiper Drive
Assembly" .
NG >> Replace IPDM E/R. Refer to PG-31, "
Removal and Installation of IPDM E/R" .
Front Wiper Does Not Return to Stop Position (After Front Wiper Operate for 10
Seconds, They Stop for 20 Seconds, and After Repeating the Operations Five
Times, They Become Inoperative)
NKS003WO
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”.

REMOVAL
1. Turn wiper switch ON to operate wiper motor, and then turn wiper switch OFF (auto stop).
2. Open hood, remove arm caps, and remove wiper arm nuts.
3. Raise wiper arms, and remove wiper arms from the vehicle.
INSTALLATION
1. Clean up the pivot area as shown in the figure. This will reduce
possibility of wiper arm looseness.
2. Prior to wiper arm installation, turn on wiper switch to operate
wiper motor and then turn it “OFF” (auto stop).
3. Push wiper arm onto pivot shaft, paying attention to blind spline.
4. Lift the blade up and then set it down onto glass surface to set
the blade center to clearance “L1” & “L2” immediately before
tightening nuts.
5. Spray washer fluid. Turn on wiper switch to operate wiper motor
and then turn it “OFF”.
6. Make sure that wiper blades stop within clearance “L1” & “L2”.
Tighten wiper arm nuts to specified torque.
7. Attach wiper arm caps.
ADJUSTMENT
Refer to WW-43, "INSTALLATION" .
