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.
