Front Wiper Does Not OperateNKS003WN
CAUTION:
During IPDM E/R fail-safe control, front wipers may not operate. Refer to PG-18, "CAN COMMUNI-
CATION LINE CONTROL" in “PG IPDM E/R” to make sure that it is not in fail-safe status.
1. ACTIVE TEST
With CONSULT-II
1. Select “IPDM E/R” by CONSULT-II, and select “ACTIVE TEST”
on “SELECT DIAG MODE” screen.
2. Select “FRONT WIPER” on “SELECT TEST ITEM” screen.
3. Touch “LO” or “HI” screen.
Without CONSULT-II
Start up auto active test. Refer to PG-24, "
Auto Active Test" .
Does front wiper operate normally?
YES >> GO TO 2.
NO >> GO TO 4.
2. CHECK CIRCUIT BETWEEN COMBINATION SWITCH AND BCM
With CONSULT-II
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”, “FR WIPER LOW”, and “FR
WIPER HI” turn ON-OFF according to wiper switch operation.
Without CONSULT-II
Refer to LT- 2 4 0 , "
Combination Switch Inspection" .
OK or NG
OK >> GO TO 3.
NG >> Check combination switch (wiper switch). Refer to LT-
240, "Combination Switch Inspection" .
3. CHECK CIRCUIT BETWEEN IPDM E/R AND BCM
Select “BCM” on CONSULT-II, and perform self-diagnosis for
“BCM”.
Displayed self
-diagnosis results
NO DTC>>Replace BCM. Refer to BCS-17, "Removal and Installa-
tion of BCM" .
CAN COMM CIRCUIT>>Check CAN communication line of BCM.
Refer to BCS-15, "

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-24, "
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-43, "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”.
