DF034 BLOCKED COMPUTER
PRESENT 1. DEF : blocked further to a shock
2. DEF : blocked by m eans of CL IP t ester.
RECOMMENDATIONS Characteristics : nothing to notice
This failure is allowing visualization of the blocking state of the airbag computer.
When present, all releasing lines are inhibited, driver’s airbag releasing being not possible.
1. DEFRECOMMENDATIONS Nothing to notice
This failure is present after airbag releasing.
It is obligatory UCE airbag replacement and of the airbag pillow after shock producing
2. DEF RECOMMENDATIONS Nothing to notice
This failure is present in the following situation s:

Diagnostic – Help
UCE A IRB AG REPL ACEMENT
New airbag computer are delivered in blocked condition in order to avoid all risks of
undesirable releasing (all releasing lines are inhibited).
This “blocked” mode is noticed by the airbag indicator lighting from the instrument panel
when setting the contact on. In order to replace t he UCE airbag, proceed as follows:
- set the c ontact off,
- dismount the central console tunnel,
- disconnect the UCE airbag connector,
- dismount the UCE airbag attachment screws,
- mount the new UCE airbag, the arrow from UCE a irbag being oriented towards front
of the vehicle, - reconnect UCE airbag connector,
- check t he system by means of the CLIP tester,
- modify if necessary the airbag computer configuration using the control “Configuration”,
- unblock the computer only in case of a failure absence, declared by the CLIP t ester.

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) .

GENERAL PRESENTATION
From electric point of view, the vehicle electric diagrams have been structured as Applied Principle
Schemes (APS), presented according to each system function. These APS diagrams also contain
details concerning the internal function of some simple electric components (contacts, relays), thus
contributi ng to a better understanding of the system functioning and of the incident good diagnosis.
Chapter 2 includes t he list of t he vehicle functional diagra ms (APS). They are divided in
electric’s supply diagrams, mass connection diagrams and system functional diagrams.
Chapter 7 includes the electric functional diagrams (APS), identified as follows: - electric c omponents marked by 3-4 figures; their identification on the electric diagrams
can be achieved by means of “Index of components” – see Chapter 3;
- connections between the electric wiring, marked by an “R” followed by figures; they are
indicated in the Chapter 4 list; - mass connections, marked by an M followed by figures or letters; they a re indicated in
Chapter 4.
Every wire of the electric diagrams is defined by an alphanumeric code representing its function,
followed by a group of letters, representing the color of that wire. Chapter 11 includes the connectors and connections between wiring, drawn from the later inlet
towards the connector/connection. The wires entering each connector socket are identified by
means of the above-mentioned drawings. The Chapter 11 also includes detailed tables about each
wi re entering the connector: wire l ocation in the connector socket, wire section, wire function
code and its destination. Chapter 11 includes the index of all wire functions in connectors and connections, namely the
list of all the connectors and connections, which helps to their easy identification in Chapter 11.
Chapter 5 includes the mass and connection positions on ve hicle and he lps to i dentify the
electric mass fixing points on it, as well as location of the connections between its wiring.
Chapter 6 i ncludes the electric c omponent position on vehicle. The location of the va rious
components with electric functions on the vehicle can be identified by means of the component list.
The cockpit fuse box is presented in Chapter 8 and contains information about its positioning
and the functional purpose of the fuse.
