When rear door LH is opened, ground is supplied

through case ground of rear door switch LH

through rear door switch LH terminal 1

to BCM terminal 63, and

to personal lamp LH terminal 1.
When rear door RH is opened, ground is supplied

through case ground of rear door switch RH

through rear door switch RH terminal 1

to BCM terminal 13, and

to personal lamp RH terminal 1.
When driver side door is unlocked by door lock and unlock switch, BCM receives a ground signal

through grounds terminals M35, M45 and M85

to power window main switch (door lock and unlock switch) terminal 17 or front power window switch
(passenger side) (door lock and unlock switch) terminal 11

from power window main switch (door lock and unlock switch) terminal 14 or front power window switch
(passenger side) (door lock and unlock switch) terminal 16

to BCM terminal 22.
When front driver side door is unlocked by driver side door lock assembly (key cylinder switch), BCM receives
a ground signal

through grounds M35, M45 and M85

to front door lock assembly (driver side) (key cylinder switch) terminal 5

from front door lock assembly (driver side) (key cylinder switch) terminal 6

to power window main switch (door lock and unlock switch) terminal 6

from power window main switch (door lock and unlock switch) terminal 14

to BCM terminal 22.
When a signal, or combination of signals is received by BCM, ground is supplied

to interior room lamp terminal 1 (without DVD player),

to map lamp terminal 2,

to front door inside handle illumination terminal 2, and

to rear door inside handle illumination terminal 2

through BCM terminal 48.
With power and supplied, interior lamp illuminates.
SWITCH OPERATION
When driver door switch is ON (door is opened), ground is supplied

through BCM terminal 1

to ignition keyhole illumination terminal 2.
And power is supplied

from BCM terminal 41

to ignition keyhole illumination terminal 1.
When any door switch is ON (door is opened), ground is supplied

through BCM terminal 47

to front step lamp (driver side and passenger side) and rear step lamp (LH and RH) terminals 2

through rear door switch (LH or RH) terminal 1

to personal lamp (LH or RH) terminals 1.
And power is supplied

from BCM terminal 41

to front step lamp (driver side and passenger side) and rear step lamp (LH and RH) terminals 1, and

to personal lamp (LH and RH) terminals 2
When map lamp switch is ON, ground is supplied
