Data monitor

Displays the input data of BCM in real time.

Active test

Gives a drive signal to a load to check the operation.

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 to “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 sup-
ply period between three steps
• MODE1 (45 sec.) / MODE2 (OFF) / MODE 3 (2 min.).
