CAUTION:

Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.

Turn wiper dial position to 4 except when checking waveform or voltage of wiper dial position.
Wiper dial position can be confirmed on CONSULT-II. Refer to WW-25, "

Preliminary CheckNKS003WK
CHECK POWER SUPPLY AND GROUND CIRCUIT
1. CHECK FUSES AND FUSIBLE LINK
Check for blown fuses and fusible link.
Refer to WW-13, "
Wiring Diagram — WIPER —" .
OK or NG
OK >> GO TO 2.
NG >> If fuse or fusible link is blown, be sure to eliminate cause of malfunction before installing new fuse
or fusible link. Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connectors.
3. Check voltage between BCM harness connector and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3. CHECK GROUND CIRCUIT
Check continuity between BCM harness connector and ground.
OK or NG
OK >> INSPECTION END

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”.

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 (HI, LO) is
operating.
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 FRONT WIPER AUTO STOP CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connector.
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.
OK or NG
OK >> Replace front wiper motor. Refer to WW-44, "Disassembly and Assembly of Front Wiper Drive
Assembly" .
NG >> Repair harness or connector.
