1.
CHECK CONDITIONS OF WINDSHIELD (RAIN SENSOR DETECTION AREA)
Make sure that rain sensor detection area of windshield was high temperature [approximately 70
°
C (158
°
F)
or more].
OK or NG
OK
>> GO TO 2.
NG
>> Wait for a while until the temperature of windshield falls.
2.
CHECK RAIN SENSOR OUTPUT SIGNAL
With CONSULT-II
1.
Select “IVMS” on CONSULT-II. And select “WIPER” on “SELECT TEST ITEM” screen.
2.
Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
3.
Make sure that the value decreases from 87 % when “RAIN
SENSOR” of “DATA MONITOR” sprinkles water with spray.
Without CONSULT-II
Sprinkle water to sensor detection area using spray, and then check voltage waveform between BCM harness
connector R4 terminal 134 and ground when wiper operates.
OK or NG
OK
>> Replace BCM.
NG
>> Replace rain sensor if voltage waveform with wiper stopped is output or if “RAIN SENSOR” of
“DATA MONITOR” on CONSULT-II is still 87 %.
When Ignition Switch Is Turned ON with Front Wiper Switch Turned to INT Posi-
tion, Front Wiper Operates though There Are No Water Drops
NKS001FE
1.
CHECK CONDITIONS OF WINDSHIELD (RAIN SENSOR DETECTION AREA)
Check rain sensor detection area of windshield for dirt such as greases.
OK or NG
OK
>> Calibration malfunctions. Refer to
WW-36, "Calibration Procedure of Rain Sensor"
NG
>> Clean rain sensor detection area of windshield fully.
When Ignition Switch Is Turned ON with Front Wiper Switch Turned to INT Posi-
tion, Front Wiper Does Not Operate though There Are Remarkable Water Drops
NKS001FF
1.
CHECK FRONT WIPER OPERATION
1.
Sprinkle water to sensor detection area using spray.
2.
Turn front wiper switch to INT position.
3.
Make sure that wiper operates when ignition switch is turned ON. (Wiper does not operate when there are
no remarkable water drops or when moisture is like a film.)
OK or NG
OK
>> Normal
NG
>> Calibration malfunctions. Refer to
WW-36, "Calibration Procedure of Rain Sensor"

Sensitivity of Rain Sensor Cannot be Controlled
NKS001FG
1.
CHECK INTERMITTENT WIPER VOLUME INPUT SIGNAL
With CONSULT-II
1.
Select “IVMS” on CONSULT-II. And select “WIPER” on “SELECT TEST ITEM” screen.
2.
Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
3.
Make sure that “INT RESIST” changes in order from approx. 0
to 1 kohm according to operation of intermittent wiper volume.
Without CONSULT-II
1.
Turn ignition switch ON.
2.
Check voltage between BCM harness connector M4 terminal 48
and ground while turning intermittent wiper volume.
OK or NG
OK
>> Replace BCM.
NG
>> GO TO 2.
2.
CHECK FRONT WIPER SWITCH
Check front wiper switch. Refer to
WW-30, "Front Wiper Switch Inspection"
.
OK or NG
OK
>> Check the following.
●
Harness for open or short between BCM and intermittent wiper volume
●
Front wiper switch ground circuit
NG
>> Replace front wiper switch.Refer to
WW-34, "Removal and Installation of Front Wiper Switch"

Intermittent Wiper Does Not Operate When Rain Sensor is Canceled
NKS001FH
1.
CHECK INTERMITTENT FRONT WIPER SWITCH INPUT SIGNAL
With CONSULT-II
1.
Select “IVMS” on CONSULT-II. And select “WIPER” on “SELECT TEST ITEM” screen.
2.
Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
3.
Make sure that “INT SW” turns ON-OFF according to operation
of front wiper switch.
NOTE:
When “DATA MONITOR” is operating, intermittent wiper does
not operate.
Without CONSULT-II
Check front wiper switch (INT) in switch monitor mode. Refer to
.
OK or NG
OK
>> GO TO 2.
NG
>> Check the following.
●
Front wiper switch: Refer to
WW-30, "Front Wiper Switch Inspection"
.
●
Harness for open or short between BCM and front wiper switch
●
Front wiper switch ground circuit
When front wiper switch is INT
: INT SW ON
When front wiper switch is OFF
: INT SW OFF

2.
CHECK FRONT WIPER AUTO STOP SIGNAL
With CONSULT-II
Make sure “WIPR AUTO STP” changes from “IGN” to “GND” accord-
ing to operation of front wiper switch.
Without CONSULT-II
1.
Turn ignition switch ON.
2.
Turn front wiper switch to LO or HI position.
3.
Check voltage between BCM harness connector and ground.
OK or NG
OK
>> GO TO 3.
NG
>> Check the following.
●
Front wiper motor
●
Front wiper motor ground circuit
●
Harness for open or short between BCM and front wiper motor
Front wiper is stopped.
: WIPR AUTO STP IGN
