< BASIC INSPECTION >[BCM]
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".
>> Work End.

POWER CONSUMPTION CONTROL SYSTEM
Sleep condition
Wake-up operation
• BCM transmits sleep wake up signal (wake up) to each unit when any condition listed below is established,
and then goes into normal mode from low power consumption mode.
• Each unit starts transmissions with CAN communication by receiving sleep wake up signals. Each unit trans- mits wake up signals to BCM with CAN communication to convey the start of CAN communication.
Wake-up condition
CAN sleep condition BCM sleep condition
• Receiving the sleep-ready signal (ready) from all units
