CONSULT-II Function (BCM)EIS002WQ
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 igni-
tion switch ON.
2. Touch "START (NISSAN BASED VHCL)".
3. Touch "BCM".
If "BCM" is not indicated, go to GI-39, "
CONSULT-II Data Link
Connector (DLC) Circuit" .
BCM diagnostic
test itemDiagnostic mode Description
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.

Work item Description
RETAINED PWR SETRAP signal’s power supply period can be changed by mode setting. Select RAP signal’s
power supply period between the following three mode settings:
MODE 1 (45 sec.) / MODE 2 (OFF) / MODE 3 (2 min.)
Test item Description
RETAINED PWRThis test is able to supply RAP signal (power) from BCM to power window system, power
sunroof system. Those systems can be operated when turning on “RETAINED PWR” on
CONSULT-II screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-II can be operated with ignition switch “OFF” position.
“RETAINED PWR” should be turned “ON” or “OFF” on CONSULT-II screen when
ignition switch ON. Then turn ignition switch OFF for checking retained power
operation. CONSULT-II might be stuck if “RETAINED PWR” is turned “ON” or “OFF”
on CONSULT-II screen when ignition switch is OFF.
Monitored item Description
IGN ON SW Indicates [ON/OFF] condition of ignition switch.
DOOR SW-DR Indicates [ON/OFF] condition of front door switch driver side.
DOOR SW-AS Indicates [ON/OFF] condition of front door switch passenger side.
