UCE AIRBAG SUPPLY VOLTAGE
PRESENT
1. DEF : micro- disconnection
2. DEF : Supply voltage too small.
3. DEF : Supply voltage too high.
RECOMMENDATIONS
Use 30 pins adapter B40 for the intervention at the level of UCE
airbag connector
1. DEF
RECOMMENDATIONS
Nothing to notice
For a micro-disconnection failure, check the supplying lines of UCE airbag:
- check the wiring connector condition at the level of UCE airbag
- check the electric mass routing condition of UCE airbag.
- check the condition of the fuse designated for UCE airbag.
- check the condition and the correct tightening of the battery plugs.
2. DEF – 3. DEF
RECOMMENDATIONS
Nothing to notice
Perform the necessary interventions in order to obtain a correct supply voltage of UCE airbag:
10.5 volts ± 0.1 < supply voltage< 15 volts ± 0.1
- check the battery charging condition
- check the charging circuit.
- check the tightening and condition of the battery plugs.
- check the electric mass presence at UCE airbag.
AFTER
Erase by means of the CLIP tester the failures memorized by UCE
INTERVENTION

DRIVER’S AIRBAG CIRCUIT
PRESENT
CC
: shortcircuit
CO
: open circuit
CC.1
: shortcircuit at + 12 volts
CC.0
: shortcircuit at mass
RECOMMENDATIONS
Characteristics: the measurement of the airbag releasing line is to be
performed only by means of the CLIP tester.
Use 30 pins adapter B40 for the intervention at the level of the
computer connector
CO - CC
RECOMMENDATIONS
Nothing to notice
Set the contact on, then block the computer by means of the CLIP tester (see “Blocking UCE
airbag”)
Set the contact off and dismount the two attachment screws of the airbag on the steering wheel.
Check the correct connection of the airbag.
Disconnect the airbag then connect the inert igniter instead of it.
Set the contact on and perform a checking by means of the CLIP tester.
Replace the airbag if the state “present failure” is becoming “memorized failure”
Turn the contact off; conect then reconect the connector of the rotating contact of under steering
wheel control.
Only CLIP tester is to be used for measuring the resistance in point C2 of the airbag circuit.
If the resulted value is not correct, replace the control under steering wheel.
Reconnect the rotating contact of the control under steering wheel, disconnect the computer
connector and connect in its place the 30 pins adapter B40.
Only CLIP tester is to be used for measuring the resistance of the driver’s airbag releasing line,
using cable A of the 30 pins adapter.
If the resulted value is not correct, check the correct connection of the 30 pins adapter (pins 10
and 11) and replace the front wiring if necessary.
If after performing these checking no failure has been noticed, check the presence of the 5 pegs
for shunt unblocking, at the 30 pins connector of UCE airbag. Check the condition of the 30
ways connector of the airbag wiring (the connector blocking system…).
AFTER
Connect UCE airbag and driver’s airbag then set the contact on.
INTERVENTION
Erase by means of the CLIP tester the failures memorized by UCE
airbag, then turn the
contact
off.
Perform again a checking by means of the CLIP tester ; in case of
failure absence, unblock the computer.
Destroy the airbag pillow, if you are replacing it (see “Destroying
procedure”)
