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.

The fuse box from the engine compartment is presented in Chapter 9, that contains information
about its location on the vehicle and the functional purpose of the relays and fuse placed on it.
The functional codes of the wires are detailed explained in Chapter 12. FUNCTIONAL DIAGRAMS INTERPRETATION
The functional diagram information included in Chapter 7 are to be i nterpreted taking i nto
consideration the explanation referring to the following example:
1= vehicle class
2= manufacturing year
3= functional electric diagram denomination
4= equipment differentiation criteria for identifying the functional electric diagram ˙
5= electric connector colour ˝
6= connector graphical representation
7= electric component index number
8= number of the fuse box on which the relay or safety fuse is m ounted
9= safety fuse identification on fuse box
10 = safety fuse value
11 = identification of wiring joints
12 = electric mass identification
13 = electric connection colour between wiring ˝
14 = electric connection identification
15 = electric connection graphical representation
16 = symbol, pages containing functional diagrams
17 = wire function code
18 = wire colour ˝
19 = functional diagram number
OBSERVATION:
1. The area ( 4) specifies the differentiating elements serving to the various functional diagrams
identification, considering the following symbols:
ABCO01 = driver’s airbag
CA = climate maintenance with air conditioning
CHAUFO = climate maintenance without air conditioning
CPE = Electric locking/unlock ing doors control
DA = assisted power steering
E0, E1, E2 = levels of equipment
LV E = front windows electric control
