System Description
POWER SUPPLY AND GROUND
Power is supplied at all times:
+through 10A fuse [No.
20, located in the fuse block (J/B)]
+to front and rear interior room lamp terminal
V1
+through 7.5A fuse [No.24, located in the fuse block (J/B)]
+to key switch terminal
V2and
+to super lock control unit terminal
V1.
When the key is removed from ignition key cylinder, power is interrupted:
+through key switch terminal
V1
+to super lock control unit terminalV18.
With the ignition key switch in the ON or START position, power is supplied:
+through 10A fuse [No.
25, located in the fuse block (J/B)]
+to super lock control unit terminal
V17.
Ground is supplied:
+to super lock control unit terminal
V16
+through body grounds terminalsM30andM19(LHD models) orM98(RHD models).
When the front driver side door is opened, ground is supplied:
+through body grounds
B23andM19(LHD models) orM98(RHD models).
+to front door switch (driver side) terminal
V3
+from front door switch (driver side) terminalV1
+to super lock control unit terminalV30.
When any other door is opened, ground is supplied to super lock control unit terminal
V31in the same man-
ner as the driver door switch.
When the front driver side door is unlocked, the super lock control unit receives a ground signal:
+through body grounds terminals
M30andM19(LHD models) orM98(RHD models).
+to front door lock actuator (driver side) (door unlock sensor) terminal
V5
+from front door lock actuator (driver side) (door unlock sensor) terminalV2
+to super lock control unit terminalV28.
When a signal, or combination of signals is received by the super lock control unit, ground is supplied:
+through super lock control unit terminal
V26
+to front interior room lamp terminalV2.
With power and ground supplied, the front interior room lamp illuminates.
INTERIOR ROOM LAMP TIMER OPERATION
When front interior room lamp switch is in the ªDOORº position, the super lock control unit keeps the front
interior room lamp illuminated for about 30 seconds when:
+unlock signal is supplied from driver's door unlock sensor while all doors are closed and key is out of
ignition key cylinder
+key is removed from ignition key cylinder while all doors are closed
+driver's door is opened and then closed while key is out of the ignition key cylinder. (However, if the
driver's door is closed with the key inserted in the ignition key cylinder after the driver's door is opened
with the key removed, the timer is operated.)
The timer is canceled when:
+driver's door is locked or
+ignition switch is turned ON.
ON-OFF CONTROL
When the driver side door, front passenger door, rear LH or RH door, back door LH or RH is opened, the
interior room lamp turns on while the interior room lamp switch is in the ªDOORº position.
