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.).
Monitor 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

Wind Deflector InspectionNIS001TB
1. Make sure the wind deflector is properly raised by manual. If a
malfunction is detected, remove and visually check it. If it is
damaged, replace it with a new one. If no damage is found, rein-
stall it properly.
Link and Wire AssemblyNIS001TC
NOTE:
Before replacing a suspect part, carefully ensure it is the source of noise being experienced.
1. Check link to determine if coated film has peeled off to such an extent that substrate is visible. Check also to determine if link is the source of noise. If it is, replace it.
2. Visually check to determine if a sufficient amount of grease has been applied to wire or rail groove. If not, add grease as required.
3. Check wire for any damage or deterioration. If any damage is found, replace wire.
