System DescriptionEKS003BQ
POWER SUPPLY AND GROUND
Power is supplied at all times:

through 10A fuse [No. 28, located in the fuse block (J/B)]

to key switch terminal 1 and

to time control unit terminal 1

through 10A fuse [No. 26, located in the fuse block (J/B)]

to interior room lamp terminal 1

to luggage room lamp terminal 1

to map lamp terminal 1 (with sunroof models)
When the key is removed from ignition key cylinder, power is interrupted

through key switch terminal 2

to time control unit terminal 18.
With the ignition key switch in the ON or START position, power is supplied

through 10A fuse [No. 5, located in the fuse block (J/B)]

to time control unit terminal 17.
Ground is supplied

through grounds terminals M27 and M70

to time control unit terminal 16.
When the driver side front door is opened, ground is supplied

through grounds B8 and B18

to front door switch driver side terminal 3

from front door switch driver side terminal 2

to time control unit terminal 30.
When any door (except back door) is opened, ground is supplied

through case ground of each door switch

to each door switch terminal 1

to time control unit terminal 31.
When back door is opened, ground is supplied:

through ground D53

to back door switch terminal 3

from back door switch terminal 1

to time control unit terminal 31.
When the driver side door is unlocked, the time control unit receives a ground signal

through grounds terminals M27 and M70

to front door lock actuator terminal 1

from front door lock actuator terminal 5

to time control unit terminal 28.
When a signal, or combination of signals is received by the time control unit, ground is supplied

through time control unit terminal 26

to interior room lamp terminal 2.

to map lamp terminal 3 (with sunroof models)
With power and ground supplied, the interior room lamp illuminates.
