RETAINED PWRThis 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” is turned “ON” or “OFF” on CONSULT-II screen when ignition switch is OFF.
Work item Description
RETAINED PWRRAP 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.).
