Check that other systems using the signal of the following systems operate normally.
Te s t I t e m D e s c r i p t i o n
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” 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 “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)/MODE3 (2 min.).
