Terminals and Reference Values for IPDM E/RNKS003WI
NOTE:
During LO operation, terminal No. 32 detects front wiper motor stopping or moving by front wiper auto stop signal.
During HI operation, terminal No. 32 detects front wiper motor stopping or moving by front wiper auto stop signal that is output from
terminal No. 44 (not from terminal No. 32).
How to Perform Trouble DiagnosesNKS003WJ
1. Confirm the symptoms and customer complaint.
2. Understand operation description and function description. Refer to WW-4, "
System Description" .
3. Perform the Preliminary Check. Refer to WW-22, "
Preliminary Check" .
4. Check symptom and repair or replace the cause of malfunction.
5. Does the front wiper and washer operate normally? If YES, GO TO 6. If NO, GO TO 4.

Preliminary CheckNKS003WK
CHECK POWER SUPPLY AND GROUND CIRCUIT
1. CHECK FUSE
Check for blown fuses.
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 >> Check harness for open or short between fuse, fusible link and BCM.
3. CHECK GROUND CIRCUIT
Check continuity between BCM harness connector and ground.
OK or NG
OK >> INSPECTION END
NG >> Repair harness or connector.

CONSULT-II Functions (BCM)NKS003WL
CONSULT-II can display each diagnostic item using the diagnostic test mode shown following.
CONSULT-II BASIC OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, and then turn
the ignition switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “BCM” on “SELECT SYSTEM” screen.
If “BCM” is not indicated, check power supply and ground of
BCM. If it is normal, refer to GI-40, "
CONSULT-II Data Link Con-
nector (DLC) Circuit" .
BCM diagnosis position Diagnosis mode Description
WIPERWORK SUPPORT Changes the setting for each function.
DATA MONITOR Displays BCM input data in real time.
ACTIVE TEST Device operation can be checked by applying a drive signal to device.
BCMSELF-DIAG RESULTS BCM performs self-diagnosis of CAN communication.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
