and pretensioners, Front side chest-level airbag: Removal - Refitting).
.
Check the condition of the driver's front side chest-level airbag connector component code 1103 (see Wiring

Position the dummy module (part no. Elé. 1835 yellow) on the driver's front side chest-level airbag connector
component code 1103.
Switch on the ignition again.
Read the fault in the AIRBAG / PRETENSIONER field.
AFTER REPAIRReconnect the computer and the ignition module for the driver's front side chest-level
airbag module
then switch on the ignition again. Clear the computer fault memory using command
RZ001 "Fault memory". Switch the ignition off and then on again.
Repeat the check using the diagnostic tool and, if there are no faults (ignore DF034

Fault finding - Fault Finding Chart
ALP 1 No communication with the airbag computer
NOTESSpecial note:
See "Introduction" for the + after ignition feed to perform fault finding on a
computer.
Use the W iring Diagrams Technical Note, New TWINGO.
Try to establish dialogue with a computer on another vehicle to make sure that the diagnostic tool is not faulty. If
the tool is not the cause and communication cannot be established with any other computer on the same vehicle,
it is possible that another computer is disrupting the multiplex network.
Proceed by successive disconnections to locate the defective computer. Check the battery voltage and perform
the necessary operations to reach the correct voltage.
(10.5 V < battery voltage < 16 V).
Check for the presence and condition of the supply fuse (F7 15A) of the airbag computer component code 756
on the passenger compartment fuse box component code 1016.
Check the connection of the airbag computer connector, component code 756 and the condition of its
connections.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check that the airbag computer, component code 756, is correctly supplied:
–Check and ensure the presence of + after ignition feed between the terminals marked earth connection
code NAP and + after ignition feed connection code AP25.
If the + after ignition feed is absent:
Check the insulation against earth and the continuity of the following connection:
–Connection code AP25 between components 1016 and 756.
Check the continuity of the following connection:
–Connection code NAP between component 756 and the earth NAP.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRWhen communication is established, deal with any faults indicated.
