CONSULT-II Function (BCM)EIS009BN
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II START PROCEDURE
Refer to GI-38, "CONSULT-II Start Procedure" .
Work Support EIS009BO
Active TestEIS009BP
Data MonitorEIS009BQ
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. Selects RAP sig-
nal’s power supply period between the following three steps.

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 in "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 LH.
DOOR SW-AS Indicates [ON/OFF] condition of front door switch RH.
