3. IPDM E/R INSPECTION
With CONSULT-II
1. Select "HI" on "ACTIVE TEST" screen.
2. When front wiper relay, and front wiper high relay are operating, check voltage between IPDM E/R termi-
nals and ground.
Without CONSULT-II
1. Turn on front wipers using the auto active test. Refer to PG-22, "
Auto Active Test" .
2. When front wiper relay, and front wiper high relay are operating,
check voltage between IPDM E/R terminals and ground.
OK or NG
OK >> Replace the front wiper motor. Refer to WW-31, "Removal and Installation of Wiper Motor and
Linkage" .
NG >> Replace IPDM E/R. Refer to PG-28, "
Removal and Installation of IPDM E/R" .
4. COMBINATION SWITCH TO BCM (1) INSPECTION
Select "BCM" on CONSULT-II. With "WIPER" data monitor, check
that "FR WIPER INT", "FR WIPER LOW" and "FR WIPER HI" turn
ON-OFF according to operation of wiper switch.
OK or NG
OK >> GO TO 5.
NG >> Check wiper switch. Refer to WW-7, "
COMBINATION
SWITCH READING FUNCTION" .
5. COMBINATION SWITCH TO BCM (2) INSPECTION
Select "BCM" on CONSULT-II. Carry out self-diagnosis of BCM.

CONSULT-II Function (BCM)EKS00BEH
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 the data link connector, then turn the
ignition switch ON.
2. Touch "START (NISSAN BASED VHCL)".
3. Touch "BCM" on the "SELECT SYSTEM" screen.
If "BCM" is not indicated, go to GI-39, "
CONSULT-II Data Link
Connector (DLC) Circuit" .
BCM diagnostic

Inspection by partWORK SUPPORTSupports inspections and adjustments. Commands are transmitted to the BCM
for setting the status suitable for required operation, input/output signals are
received from the BCM and received data is displayed.
DATA MONITOR Displays BCM input/output data in real time.
ACTIVE TEST Operation of electrical loads can be checked by sending drive signal to them.
SELF-DIAG RESULTS Displays BCM self-diagnosis results.
CAN DIAG SUPPORT MNTR The result of transmit/receive diagnosis of CAN communication can be read.
ECU PART NUMBER BCM part number can be read.
CONFIGURATION Performs BCM configuration read/write functions.
