ANTI-THEFT ALARM
DESCRIPTION
Although a key is used in the normal way to lock and unlock the vehicle, this
will not arm the alarm system. The system is armed with an RF handset, which
transmits a rolling code. This code is received by the alarm ECU, which is
mounted behind the instrument pack.
The alarm system fitted to 1999 MY Defenders has two methods of protecting
the vehicle; perimetric protection, and volumetric protection.
Perimetric protection monitors...

DESCRIPTION AND OPERATION

DEFENDER 1999 MY
OPERATION
The battery positive terminal provides a feed to the engine compartment fuse
box (C0632-1) on a brown wire. Fuse 6, fuse 7, fusible link 5 and fusible link 6
are all connected in parallel and provide a direct battery feed to the following;
·Fuse 6 (C0574-2) provides two feeds to the alarm ECU on purple/brown
wires. The first (C0061-25) is used as a power signal. The second
(C0057-8) is used to power the indicator lamp circuits (C0057-1 & C0057-6)...

DESCRIPTION AND OPERATION
DEFENDER 1999 MY4.3
The alarm ECU is connected to all the door switches (including the tail door)
and the bonnet switch. When the perimetric alarm system is armed, the ECU
monitors the switch circuits and detects open or grounded circuit. By monitoring
the circuits in this way, the alarm ECU can tell if any of the hinged panels are
open or closed. The alarm ECU is connected to the following switches;
·The alarm ECU (C0061-5) to the RH front door switch (C0054-1) on a
slate/white...

DEFENDER 1999 MY
The energised alarm relay (C0731-5) also provides a feed to fuse 20 of the
passenger compartment fuse box (C0581-20) on an orange/red wire. Fuse 20
(C0581-19) then supplies a feed to the LH (C0003-2) and RH horns (C0004-2)
on purple/black wire.
By switching the earth path on and off, the alarm ECU can control the operation
of the sounder and the horns.
The alarm ECU (C0057-4) supplies a feed to the anti-theft alarm LED
(C1060-3) on a pink wire. Because the...

ENGINE IMMOBILISATION - Td5
DESCRIPTION
The engine immobilisation system fitted to 1999 MY Defender works in
conjunction with the Alarm system. The alarm ECU sends a coded signal to the
Engine Control Module (ECM). If the signal does not match the one expected
by the ECM, the ECM will immobilise the engine.
Passive immobilisation is also fitted, with a passive coil fitted around the
ignition barrel. This will activate 30 seconds after the ignition is turned...

DESCRIPTION AND OPERATION
4.6
DEFENDER 1999 MY
When the ignition switch is turned to the crank position, current flows across
the switch (C0090-1) to the starter relay (C0151-4) on a white/red wire. With
the alarm ECU in the armed state, it also provides a feed (C0057-10) to the
starter relay (C0151-6) on the black/orange wire. As the potential difference
across the relay is 0 volts, the relay is not energized. When the alarm is
de-activated, the alarm ECU (C0057-10) withdraws the feed on the...
