1.SUNROOF SWITCH INPUT SIGNAL CHECK
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-III screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-III can be operated with ignition switch in "OFF" po-
sition. "RETAINED PWR" should be turned "ON" or "OFF" on CONSULT-III
screen when ignition switch ON. Then turn ignition switch OFF for checking re-
tained power operation. CONSULT-III might be stuck if "RETAINED PWR" is
turned "ON" or "OFF" on CONSULT-III 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.
