Check that other systems us ing the signal of the following systems operate normally.
Test Item Description
RETAINED PWR This test is able to supply RAP signal (powe
r) 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-III screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-III can be operated with ignition switch in OFF position. “RETAINED
PWR” should be turned “ON” or “OFF” on CONSULT-III screen when ignition switch is ON. Then
turn ignition switch OFF to check retained power operation. CONSULT-III might be stuck if “RE-
TAINED PWR” is turned “ON” or “OFF” on CONSULT-III 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)/MODE3 (2 min.).
