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.).

AIR PRESSURE MONITOR

AIR PRESSURE MONITOR : Diagnosis Description

INFOID:0000000005275687

DESCRIPTION

During driving, the TPMS receives the signal transmitted from the transmitter installed in each wheel, when
the tire pressure becomes low. The control unit (BCM) of this system has pressure judgment and trouble diag-
nosis functions.
When the TPMS detects low inflation pressure or another unusual symptom, the warning lamps in the combi-
nation meter comes on.

SELF DIAGNOSTIC PROCEDURE (WITH CONSULT-III)

With CONSULT-III

• Touch “SELF-DIAG RESULTS” display to show malfunction experienced since the last erasing operation.

Refer to

BCS-50, "DTC Index"

SELF DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-III)

Without CONSULT-III

To start the self-diagnostic results mode, ground terminal of the tire pressure warning check connector. The
malfunction location is indicated by the warning lamp flashing.

NOTE:
When the low tire warning lamp flashes 5 Hz and continues repeating it, the system is normal.

ERASE SELF-DIAGNOSIS

With CONSULT-III

Perform applicable inspection of malfunctioning item and then repair or replace.

Turn ignition switch “ON” and select “SELF-DIAG RESULTS” mode for “AIR PRESSURE MONITOR” with
CONSULT-III.

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.
