2005 LOTUS ELISE ECU

Disarming the AlarmTo disarm the alarm, press once, and for a full second, the
larger button on the transmitter fob. This command will be
acknowledged by:
- 1 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:
- 1 pulse flashing: door, engine cover/boot lid or body front access panel.
- 2 pulse flashing: movement detected in cabin by microwave sensor.
- 4 pulse flashing: tampering with ignition circuit.
- 6 pulse flashing: interruption of battery supply.
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
page 18) from step 3.

Intrusion SensingA 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 shield 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 Siren To enhance personal security, with the system in a fully armed
state (after 45 second arming period), the siren may be manually
triggered by pressing the transmitter smaller button. The siren
will sound and the turn lamps flash for 15 seconds. To stop the siren, press either of the two transmitter buttons.

Transmitter Fob Battery ReplacementThe 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 insert
-
ing 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 following 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 con-
stantly.
- 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 car. If one
transmitter is lost or damaged, a replacement should be ob
-
tained immediately from your dealer, and programmed to the car alarm controller using a functioning transmitter fob and the
system owner’s unique Personal Identification Number (PIN).
Up to 4 transmitter fobs can be matched with the alarm system, but all fobs must collectively undergo the single programming
operation:
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. Turn the ignition on and off 3 times within 7 seconds; the
security tell tale in the tachometer will light for 3 seconds.
4. 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.
5. Repeat operation (4) 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.
6. If the PIN is correct, the security tell tale will be lit. Test op
-
eration of each transmitter fob.
Disconnecting the Car Battery If the battery is to be disconnected, refer to the ‘Battery’
section later in this handbook which includes the following precaution:
- Before disconnecting the battery, ensure that the alarm system
is disarmed and mobilised.

Interior LampThe interior lamp is located centrally in the rear bulkhead trim
panel, and incorporates a three position rocking lens:
• Lens rocked upwards; lamp is switched off.
NOTICE:
Use this position only temporarily as required. Arm-
ing the security alarm system with the lamp switched off may
exclude the doors from activating the alarm.
• Lens central; lamp is switched on with or without ignition.
NOTICE: To guard against flattening the battery, take care
not to leave the lamp on when parking the car, or to switch
it on accidentally when using the storage space behind the
seats.
• Lens rocked downwards; a courtesy mode applies, where the
lamp is switched on whenever a door is opened, and goes out when both doors are closed. This is the normal position
and should be used whenever leaving the car.
Sun Visors To help reduce sun glare, pivoted visors are provided for both
driver and passenger. Swing down the visor from the windscreen
header rail as required.
