GENERAL
NOTE:
From 1997 the
ESPACE
is fitted with a single deco-
der unit which enables both the engine immobili-
ser operated by a coded key transponder recogni-
tion system (called a
coded key transponder
en-
gine immobiliser) and the infra red remote
control to be controlled .
This system is fitted to petrol or diesel vehicles.
Petrol vehicle:
the engine is immobilised by the
injection computer.
Diesel vehicle:
the engine is immobilised by a co-
ded solenoid valve (on the injection pump).
Coded electronics, independent of the infra red
remote control function (which operates without
batteries), are incorporated into each ignition key
head.
The vehicle’s infra red remote control is used to:
- lock or unlock the openings,
- control the courtesy lights (timing),
- set and unset the alarm.
When the ignition is switched on, an antennan
antenna ring located around the ignition switch
interrogates and senses the code emitted by the
key and transmits it to the decoder unit.
There is no action on the engine immobiliser sys-
tem.
If the decoder unit recognises the code, starting of
the vehicle will then be authorised.
The infra red code changes and will therefore be
different each time the remote control is pressed
in order to prevent any copying.
The engine immobiliser is activated a few seconds
after the key is removed from the ignition, indica-
ted by the flashing of the red indicator light on
the roof console.
Therefore, when one of the transmitters is chan-
ged, resynchronisation will be necessary.
In the event of a key recognition system fault, a
security code can be entered using the door
locking button (either side) and the red indicator
light located on the roof console (or using the
XR25).
IDENTIFICATION
On these vehicles, the coded key transponder
head identification number has
eight characters
starting with the letter
Z
.
This code will be communicated to the repairer (at
his request) by the local assistance network (accor-
ding to country, example
Delta Assistance
on
08
00
05 15 15
for France, for U.K. contact the
N.V.S.R. by fax only).

(ISO

should be illuminated (code pre-
sent).
With this generation of engine immobiliser, the
repairer must not pass on the confidential code to
the customer when a repair is carried out (auto-
matic activation of the system 10 seconds after the
ignition is switched off (within one minute for the
UK) when a repair is carried out).
