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-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 SET

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.).
