Fault finding – Fault Finding Chart
ALP 1 No communication with the airbag computer
NOTESSpecial note:
See Introduction/Procedure section to activate the forced + after ignition feed to
run fault finding on a computer.
Try to establish dialogue with a computer on another vehicle to check that the diagnostic tool is not faulty.
If the diagnostic 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 computer at fault.
check the battery voltage and carry out the operations required to obtain a correct voltage.
(10.5V < U battery < 16V)
Check the presence and condition of the airbag computer supply fuse.
Check that the computer connector is properly connected and check the condition of its connections.
Check that the supply to the computer is correct:
– Disconnect the airbag computer and fit the 22-track adapter Elé. 1685.
– Check and ensure the presence of + after ignition feed between the terminals marked earth and + after ignition
feed.
Check that the power supply to the diagnostic socket is correct:
–+ Before ignition on track 16.
– + after ignition en track 1.
–Earth on tracks 4 and 5.
Check using the 22-track adapter Elé. 1685. Check the continuity and insulation of the lines of the airbag
computer/diagnostic socket connection between:
Bornier track CAN H
Bornier track CAN LTrack 6 of the diagnostic socket
Track 14 of the diagnostic socket
If dialogue has still not been established after these checks, contact Techline.
AFTER REPAIRWhen communication is established, deal with any faults indicated.
