INSPECTION AND ADJUSTMENT
• When replacing BCM, you must perform WRITE CONFIGURATION
with CONSULT-III.
• Complete the procedure of WRITE CONFIGURATION in order.
• If you set incorrect WRITE CONF IGURATION, incidents will occur.
• Configuration is different for each vehicle mode l. Confirm configuration of each vehicle model.
CONFIGURATION : Special Repair RequirementINFOID:0000000005146383
1. WRITING VEHICLE SPECIFICATION
Perform “WRITE CONFIGURA TION” with CONSULT-III.
When writing saved data>>GO TO 2
When writing manually>>GO TO 3
2. PERFORM “WRITE CONFIG URATION - CONFIG FILE”
Perform “WRITE CONFIGURATION - Config file” with CONSULT-III.
>> WORK END
3. PERFORM “WRITE CONFIGURA TION - MANUAL SELECTION”
For “WRITE CONFIGURATION - Manual selection”, using the following flow chart, identify the correct model
and configuration list.
Confirm and/or change setting value for each item according to the configuration list.
Depending on CONSULT-III software version being used, some or all of the write configuration items shown in
the following configuration lists may be displayed. If an item does not display on the CONSULT-III “WRITE
CONFIGURATION - Manual selection” screen, then it is an auto setting item and it cannot be manually set or
changed.
NOTE:
Confirm vehicle model. Refer to GI-20, "
Model Variation".

AIR PRESSURE MONITOR : Diagnosis DescriptionINFOID:0000000005146412
DESCRIPTION
During driving, the TPMS receives the signal transmitt ed 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 DIAGNOSIS (WITH CONSULT-III)
With CONSULT-III
• Touch “SELF-DIAG RESULTS” display to show malfunction experienced since the last erasing operation. Refer to WT-11, "
CONSULT-III Function (BCM)".
SELF DIAGNOSIS (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.
