CONSULT-II Functions (IPDM E/R)NKS003WM
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 “IPDM E/R” on “SELECT SYSTEM” screen.
If “IPDM E/R” is not indicated, check power supply and ground
of IPDM E/R. If it is normal, refer to GI-40, "
CONSULT-II Data
Link Connector (DLC) Circuit" .
Diagnosis Mode Description
SELF
DIAG RESULTS Refer to PG-21, "SELF-DIAG RESULTS" .
DATA MONITOR The input/output data of IPDM E/R is displayed in real time.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ACTIVE TEST IPDM E/R sends a drive signal to electronic components to check their operation.

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”.

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”.
1. CHECK FRONT WIPER STOP SIGNAL

Select “IPDM E/R” on CONSULT-II. With “DATA MONITOR”, make
sure that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with
wiper LO operation.

while front wiper motor is stopped and while front wiper LO is operat-
ing.
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 CIRCUIT BETWEEN FRONT WIPER MOTOR AND GROUND
1. Turn ignition switch OFF.
