CONSULT-II Function (IPDM E/R)EKS00P54
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II 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 carries out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to data link connector, and then turn igni-
tion switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “IPDM E/R” on “SELECT SYSTEM” screen.
If “IPDM E/R” is not displayed, refer toGI-50, "
CONSULT-II Data

Front Wiper Does Not Return to Stop Position (After Front Wiper for 10 Sec-
onds, They Stop for 20 seconds, and After Repeating the Operations Five
Times, They Become Inoperative)
EKS00P57
CAUTION:
lWhen auto stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers front wipers are locked, and stops wiper output. That causes this
symptom.
lThis status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
ITEMS SHOWS “BLOCK”.
1.CHECK FRONT WIPER STOP SIGNAL
With CONSULT-ll
1. Select “BCM” on CONSULT-II. Select “WIPER” on “SELECT
TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
Make sure that “WIP AUTO STOP” turns “ACT P” - “STOP P”
linked with wiper operation.
Without CONSULT-ll
GO TO 2.
Does the front wiper operate normally?
YES >> Replace IPDM E/R. Refer toPG-26, "Removal and
Installation of IPDM E/R".
NO >> GO TO 2.
2.CHECK IPDM E/R
Check voltage between IPDM E/R harness connector and ground
while front wiper motor is stopped and while it is operating.
OK or NG
OK >> Replace IPDM E/R. Refer toPG-26, "Removal and
Installation of IPDM E/R".
NG >> GO TO 3.
