REPLACEMENT OF COCKPIT INTERMEDIARY RELAY
DISMOUNTING
Disconnect the battery (-) terminal.
Dismount the relays assembly and UCE decoder.
Remove the relay: flash (6), timer (7 ), signaling (8) or speed limit warning ( 9) from their
connectors. Mark the identification of the relays mounting position.
REMOU NT I NG
Reconnect the relays observing the mounting position prior to dismountin g.
Remount the assembly relays and UCE decoder.
Reconnect the battery (-) terminal.
Pe rform functional tests, noticing the correct operation of all consumers supplied by means of the
cockpit relays asse mbly and UCE decoder.
OBSERVATION :
A fter battery reconnecting, re- program the clock, and for vehicles equipped with
p rogrammable radio tape player, re-introduce the radio code.

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.

Diagnostic – Failure locating tree
Ensure t hat not CL IP tester i s the failure cause – try its communication with some ot her
vehicle UCE airbag. If CLIP tester is not the failure cause and the dialogue is not established
with no other computer of the same vehicle, it is possible that another damaged computer is
perturbing the diagnostic lines L and K.
Proceed by consecutive disconnection for damaged computer locating.
Check the battery voltage and perform the necessary interve ntions in order to obtain an
adequate vol tage, with the value between 10.5 volts and 15 volts.
Check the presence and condition of the supply fuse of UCE airbag.
Check the correct connection of the computer connector and the cables condition.
Check the computer correct supplying: -Disconnect UCE airbag then connect the 30 pins adapter B40.
- Check and ensure voltage presence be tween plugs marked mass and +DC (+ after
contact)
Check the correct supplying of the diagnostic socket: -supply + permanent at pin 16
- mass at pin 5
Check the continuity and insulation of the connection lines diagnostic socket / UCE airbag:
- plug 23 of UCE airba g pin 15 diagnostic socket (line L)
- plug 9 of UCE a irbag pin 7 di agnostic socket (line K)
If dialogue is not established after these checking, replace UCE airbag (see c hapter “UCE
airbag replacement) .
