< FUNCTION DIAGNOSIS >
DIAGNOSIS SYSTEM (BCM)
The BCM records the following condition at the moment a particular DTC is detected.
• Vehicle Speed
• Odd Trip Meter
• Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
• The number is 0 when a malfunction is detected now.
• The number increases like 1
→
2
→
3...38
→
39 after returning to the normal condition whenever ignition
switch OFF
→
ON.
• The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
AIR PRESSURE MONITOR
AIR PRESSURE MONITOR : Diagnosis Description
INFOID:0000000003579703
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 low tire pressure warning
lamps in the combination meter comes on.
SELF DIAGNOSTIC PROCEDURE (WITH CONSULT-III)
With CONSULT-III
Touch “SELF-DIAG RESULT” display shows malfunction experienced since the last erasing operation. Refer
to
.
SELF DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-III)

ERASE SELF-DIAGNOSIS
With CONSULT-III
1.
Perform applicable inspection of malfunctioning item and then repair or replace.
2.
Turn ignition switch ON and select “SELF-DIAG RESULTS” mode for “AIR PRESSURE MONITOR” with
CONSULT-III.
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.
