NOTESUse the Wiring Diagrams Technical Note, New TWINGO.
Check the condition of the airbag computer connector component code 756 (see Wiring Diagram Technical
Note, New Twingo, Component code 756 and Technical Note 6015A, Repairing electrical wiring, Wiring:
Precautions for repair).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check fuse F7 15 A on the passenger compartment fuse box, component code 1016.
With the ignition on, check for + 12 V on connection AP25 of the airbag computer, component code 756:
10.5 V ± 0.1 < voltage OK < 16 V ± 0.1.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
–Check the battery charge.
–Check the charge circuit (see 80A, Battery).
–Check the tightness and the condition of the battery terminals.
–Check the computer earth connection NAP.
Use the universal bornier to check the insulation and continuity of the following connections:
–Connection code AP25 between components 756 and 1016,
–Connection code NAP on component 756.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRClear the computer fault memory. Switch off the ignition.
Carry out the check again using the diagnostic tool and, if there is no fault, unlock the
computer.
