DATA MONITOR
BCM diagnostic test item Check item diagnostic test mode Content Refer to page RETAINED PWR Work support Changes setting of each function.
RF-15
Data monitor Displays the input data of BCM in real time.RF-15
Active test Gives a drive signal to a load to check the operation.RF-15
Test Item Description
RETAINED PWR This test is able to supply RAP signal (power) from BCM (body control module) to power window
system and power sunroof system (if equipped). 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 is ON. Then turn
ignition switch OFF to check retained power operation. CONSULT-II might be stuck if “RETAINED
PWR” is turned to ON or OFF on CONSULT-II screen when ignition switch is OFF.
Work item Description
RETAINED PWR Rap signal’s power supply period can be changed by mode setting. Selects rap signal’s power
supply period between three steps

MODE1 (45 sec.) / MODE2 (OFF) / MODE 3 (2 min.).
