BCM is activated with low current consumption mode.

CAN communication is not active.

When CAN communication operation is detected, it switches to CAN communication status.

When a state of the following switches changes, it switches to CAN communication state:
–Ignition switch
–Key switch (without Intelligent Key)
–Key switch and ignition knob switch (with Intelligent Key)
–Hazard switch
–Door lock/unlock switch
–Front door switch (LH, RH)
–Rear door switch (LH, RH)
–Back door lock assembly
–Combination switch (passing, lighting switch 1st position, front fog lamp)
–Keyfob (lock/unlock signal)
–Front door key cylinder switch LH

When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.

Status of combination switch reading function is changed.

ting value for each item according to the configuration list.
Depending on CONSULT-II 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 appear on the CONSULT-
II "WRITE CONFIGURATION" screen(s), then it is an auto setting item and it cannot be manually set or
changed.
NOTE:
Confirm vehicle model on IDENTIFICATION PLATE. Refer to GI-47, "
Model Variation" .
10. Touch "CHNG SETTING" on "WRITE CONFIGURATION" screen.
CAUTION:
Make sure to touch "CHNG SETTING" even if the indicated configuration of brand-new BCM is
