INTERIOR LAMPS
DESCRIPTION
Defender 1999 MY vehicle are fitted with an interior lamp in the front of the
vehicle. 110 Station wagon vehicles are also fitted with a rear interior lamp.
Both lamps can be switched on manually using their integral switches. If any
door, including the tail door are opened, the lamps will illuminate.
The lamps are controlled by the alarm ECU. The ECU contains a time out
feature which switches off the interior lamps after eight minutes if any door is
left open, thus preventing unnecessary battery drain.
OPERATION
90/110 Hard Top and 90 Station Wagon
Feed from the battery positive terminal is connected to fuse 6 and fuse 7 of the
engine compartment fuse box (C0632-1) by a brown wire. Fuse 6 (C0574-2)
supplies a feed to the alarm ECU (C0057-8) on a purple/brown wire. Fuse 7
(C0574-1) supplies a feed to the front interior lamp (C0355-3) on a
purple/brown then purple wire.
The interior lamp has an integral switch. With this switch in the normal (central)
position, the lamp is earthed (C0355-1) via the alarm ECU (C0061-1) on a
purple/white wire. The alarm ECU will only supply the lamp with an earth path
is either of the front doors, or the tail door, are opened.
The alarm ECU (C0061-5) is connected to the drivers door switch (C0054-1) by
a slate/white wire. The passenger door switch (C0033-1) and the tail door
switch (C0615-1) are wired in parallel and are connected to the alarm ECU
(C0061-16) by purple/blue wires.
If the internal switch is moved to the forward ON position, the feed from fuse 7
flows across the interior lamp (C0355-3 & C1210-1) directly to earth on a black
wire. Moving the switch to the rear OFF position, breaks the circuit to prevent
the lamp from illuminating when any of the doors are opened.
