Two ﬂashes of the hazard warning lamps;

Continuous ﬂashing of the security tell tale.

Check that these indications occur. If not, press the button a second time, as the ﬁrst press may have

only switched off the passive immobilisation (see above).

Note that if the system is armed when a door or engine cover/front access panel is not fully closed, a

continuous buzz will be heard as warning. If still open after expiry of the arming period, (see below) the alarm

will be armed with that switch group (both doors, or front/rear access lids) excluded from the circuit.

After arming the system, the engine is immediately immobilised, but a period of approximately 45 seconds

must elapse before all functions and sensors become fully active. After this time, the alarm will be triggered

by any of the following actions:

Interruption of the vehicle battery power supply.

Energising the ignition circuit (‘hot wiring’).

Opening a door;

Opening the engine cover or a front access panel.

Movement detected within the cabin.

When triggered, the hazard warning lamps will ﬂash and the electronic wailing siren will sound for a

period of approximately 30 seconds before closing down and resetting, ready for any further triggering input.

If a trigger is continuously present, the alarm will repeat after a short delay, and continue in this sequence for

about ten cycles.

To silence the siren when triggered, press once, and for a full second, the larger button on the transmitter

fob. This will not affect the status of the alarm which will remain armed.

Disarming the Alarm

To disarm the alarm, press once, and for a full second, the larger button on the transmitter fob. This com-

mand will be acknowledged by:

One ﬂash of the hazard warning lamps;

Extinguishing of the security tell tale.

If the alarm had been triggered during the last armed period, the disarm command will be acknowledged

by the hazard lamps ﬂashing 4 times, and the buzzer sounding 4 times. The security tell tale will then ﬂash a

code to indicate the triggering source:

One pulse ﬂashing: door, engine cover/boot lid or body front access panel. On USA cars, check that the

interior lamp is not switched off.

Two pulse ﬂashing: movement detected in cabin by microwave sensor.

Four pulse ﬂashing: tampering with ignition circuit.

Six pulse ﬂashing: interruption of battery supply.

Seven/Eight pulse ﬂashing: serial data fault; alarm harness including microwave sensor cables and im-

mobiliser fuse.

The coding will be deleted when the ignition is next turned on.

Emergency Disarming/Mobilising

If the transmitter fobs are lost or damaged, the alarm system owner’s unique PIN may be used to disarm

the alarm and/or mobilise the engine

provided that access is available to the cabin. Follow the transmitter fob

programming instructions (see later) from step 3.

Intrusion Sensing

A microwave sensor is mounted behind the cabin rear bulkhead trim panel, and is able to detect substantial

physical movement within the cockpit, and trigger the alarm. Microwave transmissions are blocked by metal

objects, so it is important not to corrupt the signal by placing such items on the bulkhead ledge.

If desired, the alarm may be armed without the intrusion sensor or battery interruption circuits being active

by arming the system in the usual way with the transmitter larger button, and within 20 seconds, pressing the

smaller button twice.

Manual Activation of Horn/Siren

To enhance personal security, with the system in an armed state, the siren may be manually triggered by

pressing the transmitter smaller button. The horn/siren will sound and the turn lamps ﬂash for 15 seconds. To

stop the alarm, press either of the two buttons.

Transmitter Fob Battery Replacement

The transmitter fobs will normally operate within a range of 5 metres from the car, but this may be reduced

by the presence of other radio signals in the vicinity. A small LED tell tale on the transmitter fob will ﬂash whilst

the button is held down to indicate correct operation, but if the lamp ﬂashes irregularly or only once, transmitter

battery replacement is required.

The transmitters are powered by a long life 3V Lithium battery, type CR2032, which with normal use should

last for 3 years. To ensure continuity of operation, it is recommended to renew the batteries every 12 months:

Using a small screwdriver, prise open the case in the areas marked ‘open’.

Remove the old battery and wait for 10 seconds before inserting the new battery with +ve sign uppermost,

and holding the battery only by the periphery.

Align the locating studs, and ﬁrmly press the case together.

The transmitter should now operate normally, but may require re-synchronisation with the control unit.

Transmitter Re-synchronisation

If at any time the transmitter does not function, and the battery is known to be good, carry out the follow-

ing re-synchronisation procedure:

Stand close to the car and hold down both buttons on the transmitter until the LED on the fob is extinguished

(approx. 10 seconds).

Release both buttons; the fob tell tale should come on constantly.

Press the larger button for one second (the fob tell tale will ﬂash). Synchronisation is complete.

Programming Additional Transmitter Fobs

Two transmitter fobs are provided with the new vehicle. If a transmitter is lost or damaged, a replacement

should be obtained immediately from your dealer, and programmed to the vehicle alarm controller using the

system owner’s unique Personal Identiﬁcation Number (PIN). Up to four transmitter fobs can be matched with

the alarm system, but all fobs must collectively undergo the single programming operation:

a). Before programming the transmitters, the PIN should ﬁrst be veriﬁed. If the PIN is incorrect and a working

fob is prepared for reprogramming, all fobs may be disabled. To verify the PIN;

With the car immobilised (tell tale ﬂashing), follow steps (3i) to (3iii) below (i.e. do not prepare any fobs).

If the PIN is correct, the tell tale should be extinguished, and the system mobilised. If not, the PIN is incor-

rect.

b). Having veriﬁed the PIN as above, proceed as follows:

1. Press, simultaneously, both buttons on a transmitter fob until the fob tell tale stops ﬂashing (approx. 10

seconds). On release of the buttons, the fob tell tale will light.

2. Repeat operation (1) for ALL the transmitter fobs required to operate the system.

3. If the system is immobilised (security tell tale ﬂashing):

Turn the ignition on and off 3 times within 7 seconds; the security tell tale in the tachometer will light

for 3 seconds.

ii)

Enter the PIN: Immediately the tell tale goes out, switch ON the ignition and count the number of

security tell tale ﬂashes until equal to the ﬁrst number of the PIN, then turn the ignition OFF, then back ON

again.

iii) Repeat operation (ii) for the remaining 3 digits of the PIN, remembering to turn the ignition OFF and

back ON after each code number.

Note: If at any time a mistake is made when entering the PIN, turn the ignition OFF for 10 seconds and

re-commence entering the PIN.

iv). If the PIN is correct, the security tell tale will be out. Carry on with step 4.

4. With the system mobilised (security tell tale out):

Turn the ignition on and off 3 times within 7 seconds; the security tell tale in the tachometer will light

for 3 seconds.

ii)

Enter the PIN: Immediately the tell tale goes out, switch ON the ignition and count the number of

security tell tale ﬂashes until equal to the ﬁrst number of the PIN, then turn the ignition OFF, then back ON

again.

iii) Repeat operation (ii) for the remaining 3 digits of the PIN, remembering to turn the ignition OFF and

back ON after each code number.

Note: If at any time a mistake is made when entering the PIN, turn the ignition OFF for 10 seconds and

re-commence entering the PIN.

5. After ﬁnishing step (4) with the ignition on, within 7 seconds, press once the large button of each transmit-

ter fob.

6. Turn off the ignition.

7. Test operation of each transmitter fob.

MP.2 - CENTRAL DOOR LOCKING (IF FITTED)

The central door locking (CDL) operates on the driver’s and passenger’s doors in conjunction with the

security alarm system, which includes CDL circuitry in the Cobra 8186 alarm controller.

To lock the car, remove the ignition key, close both doors and check that the engine cover and front body

access panels are secure. Arm the security alarm in the usual way by pressing once, for a full second, the

larger of the two buttons on the transmitter key. This action will both arm the alarm and electrically lock the

driver’s and passenger’s doors.

If it is desired to lock the doors from inside the vehicle, for example to deter highjack attempts, a CDL

rocker switch is provided on the front of the gear lever shroud which should be pressed to the right to lock both

doors with or without the ignition switched on. Alternatively, the doors can be locked individually by depress-

ing the button at the rear end of each door sill. Note that whichever locking method is used, the doors will be

‘deadlocked’ such that the interior door release handles are inoperative.

To unlock the doors, press once, for a full second, the larger button on the transmitter key. The alarm will

be disarmed and both doors unlocked. Alternatively, from inside the car, press to the left the rocker switch on

the gear lever shroud to unlock both doors, or raise the sill button on each door. Note that in the event of a

vehicle collision which causes the safety inertia switch to be tripped, the doors will automatically be unlocked.

Notes:

In the event of a ﬂat vehicle battery, the

central door locking will not operate. The

doors can be unlocked from outside only

after:

Elise; opening the engine cover and

restoring power to the battery by

substitution, re-charging or ‘jumping’ to

a second battery.

Exige; removing the front body passenger

side access panel and providing a 12 volt

supply to the auxiliary power point.

To lock the car with a ﬂat or disconnected battery, use the mechanical key in each exterior door button

to disconnect each release button from the latch. This technique does not 'deadlock' the interior release

handles, but does allow continued key access to the car until restoration of battery power.

To deadlock the car with a ﬂat vehicle battery, or without the use of the transmitter or mechanical key,

close and lock one door using the sill button, and for the second door, hold the exterior release button

pressed in and depress the sill button before closing the door. Access is now available only on restoration

of electrical power.

Door Locking Actuator

A CDL actuator is screw ﬁxed to the door shell below the latch mechanism, and uses a link rod which

passes through the innermost hole on the latch lever, before continuing upwards to the door sill button. For

replacement details, refer to sub-section BP.17.

Modules, Fuses & Relays

A CDL module is mounted on the top of

the scuttle beam at the extreme end on the

driver's side, accessible after removal of the

fascia top trimmed panel and face level vent

trunking (if ﬁtted). A battery feed for the CDL

system is provided from fuse A22 (7.5A).
