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 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.).

ERASE SELF-DIAGNOSIS
With CONSULT-III
1. Perform applicable inspection of malfuncti
oning item and then repair or replace.
2. Turn ignition switch “ON” and select “SELF-DIAG RESULTS” mode for “AIR PRESSURE MONITOR” with
CONSULTIII.
3. Touch “ERASE” on CONSULT-III screen to erase memory.
Without CONSULT-III
• In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is
stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned “ON” and “OFF”.
• However, this information is erased by turning ignition switch “OFF” after performing self-diagnostic or by
erasing the memory using the CONSULT-III.
