Diagnostic – Help

UCE A IRBAG REPLACEMENT

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 the UCE airbag, proceed as follows:

- set the contact 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 airbag being oriented towards front

of the vehicle,

- reconnect UCE airbag connector,
- check the 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 tester.

Diagnostic – Failure locating tree

Ensure that not CLIP tester is the failure cause – try its communication with some other
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 interventions in order to obtain an
adequate voltage, 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 between 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 airbag         pin 15 diagnostic socket (line L)
- plug 9 of UCE airbag           pin 7 diagnostic socket (line K)

 If dialogue is not established after these checking, replace UCE airbag (see chapter “UCE
airbag replacement).

 Missing dialog with the airbag computer.

DISMOUNTING

Dismount the battery (-) terminal.
Dismount the front door panel (see chapter 72 “Front door panel”)
Disconnect the speaker connector (1)
Dismount the front door deflective panel.
Disconnect and detach from clips actuator’s  connector (2)
Disconnect window electric regulator connector (3) (for Solenza Dacia vehicles)
Cut attachment clip (4) of the front door wiring. Mark the mounting position of the attachment

clip.

Remove the wiring protector (5) from the front door and front pillar.  Mark the mounting

position of  the protector.

Remove the front wiring from the door. Mark the mounting position of the fron wiring.
Carefully, remove protector off the wiring

REMOUNTING

Perform the dismounting operations in the reverse order, observing the mounting position

previously existent.

Replace the attachment clip (4).
Check the actuator’s operation, the windows and speaker operation.
