IGNITION AND INJECTION

PRINCI PLE
When the engine is in “closed loop” phase, the enriching adjustment is correcting the injection
time in order to be able to obtain a fuel mixture with the enriching as close as possible to 1. The
co rrec tion value is fluctuating around the value 128, within the limits 0 and 255.
Although, variations in time of the components elements parameter of the injection system may
occur, this leading to the enriching correction displacement towards 0 or 255, in order to maintain
the enrichment at the value 1. The adaptive correction is allowing the “resetting” of the injection chart in order to bring the
enrichment adju stment to the average value 128 and the achievement of an effective constant
correc tion for the enrichment or impoverishment of the fuel mixture.
The adap tive correction of the enrichment adjustment is divided into two components:
-p reponderant adaptive correction at engine medium or high charges (adaptive enriching
during running); -prepo nderant adaptive correction at engine idling or small charges (adaptive enriching
during idling).
The adap tive corrections are considering the value 128 as an average value after performing
the activation (after erasing the memorized failures) and they have for the next parameters, the
following limit va lues:
PR030 = Adaptive enriching during running 80< X < 176
PR031 = Adaptive correction during idling 80 < X < 176.
The ad apti ve corrections are not applied unless the engine is warm (water temperature > 80°C),
and it is in the “closed loop” phase and the pressure from the inlet manifold is in a certain interval.
It is necessary that engine has been run in “closed loop” phase in many of the inlet manifold
pre ssure areas, for which the adaptive correction evolution is starting the compensation of the
engine running enriching dispersions.
Therefor e, further to UCE injection re-activation, after erasing the memorized failures, when
the values PR030 and PR031 are 128, it will be necessary that a specific road test is to be per-
formed.

DISMOUNTING
After identification and elimination of the real cause of the battery discharging, proceed as
follows: Remove the plastic protector from the plus plug of the battery.
Dismount the attachment nut of the mass wiring from the minus plug of the battery.
Dismount the attachment nut of the wiring from the plus plug of the battery.
Dismount the battery attachment clamp screw.
Carefully take off the battery.

Perform the dismounting operations in the reverse order. After that, reset the radio by intro-
ducing the radio code (if the vehicle is equipped with radio) and adjust the dashboard clock.

“ Expert “ operation mode.
In order t o pass in c onfiguration (Expert mode), perform a long pushing (4 seconds) on
“source” key until a beep is heard. This is allowing the following functions adjustment:
- AF mode activation ( automatic resetting)
-V olume modifi cation subject to the vehicle speed ( 5 for maximal modification, 0 for
modification canceling) -Loudness mode activation
- Assisted radio receiver mode activation
-N umber of speakers activation (2 or 4)
- Manual or dynamic list selection
REMARK: during c onfiguration one impulse on “source” ke y i s canceling t he
modifications.
Volume
The volume may be settled subject to vehicle speed. For the activation of this function, select
the desired volume modification curve, by means of the “ Expert “ mode (push longer on the
“ source” key, until a beep is heard): 5 for maximal modification, 0 for modification canceling.
REMARK : In order this function becomes operational check that radio is correctly
connected.

AIRBAG SYSTEM CONFIGURATION
Because the vehicle is e quipped only the
driver’s airbag, it i s necessary the UCE airbag
configuration only “with driver’s airbag”.
In case UCE airbag configuration does not
match with the vehicle equipping, the airbag
indicator will remain lighted.
-S elect menu “ Diagnostic”
- Select and validate vehicle type.
-S elect and validate diagnostic system
“Airbag/ Pre-tensioning systems” - Select mode “ Control”.
-S elect function “ Programmi ng” then
configure the computer only “ With driver’s
airbag ”.
-S et the contact off then reset t he contact
on for in order to validate the configuration.
In the case of the UCE airbag configuration, the
airbag indicator from the instrument panel is
remaining lighted because new UCE airbag are
delivered in blocked state. -S elect mode “ Control”, select mode “
Configuratio ns reading” or select m enu
“States list” and e nsure that modification ha s
been taken into consideration.
AT T E N T I ON!
N on-observing of these prescriptions may
ge ne rat e an abnorm a l ope rat i on of t he
sy stem, even undesirable releasing of the
airbag. UCE airbag may accept up to maximum
4 ai rbag re leasing (c ert ai n e lements are
loosing their nominal characteristics). It is
n ot necessary the systematic replacement
after each airbag releasing.
UCE AIRBAG UNBLOCKING
Af ter replacing UCE airbag it is necessary
the re leasing lines unblocking. The same
method as for the UCE airbag blocking is to
be used, by validation c ontrol “ Computer
unblocking”. The airbag indicator from the
instrument panel is getting off.
REMARK:
The 30 pins connecto r of the UCE
airbag has a shunt circuit that is short-
circuiting the different transmitting
lines of the releasing signal when this
one is disconnected, avoiding the
undesirable releasing of this system (by
antenna effect, for instance)
REMARK:
UCE airbag supply and the
pyrotechnic gas generator is performed
by means of the vehicle bat tery. UCE
airbag is disposing of a reserve electric
energy enabling nevertheless the airbag
r eleasing even if, at the be ginning of a
shock, the v ehicle battery i s not anymore
supplying the UCE airbag.
