Fault finding – Interpretation of statuses
–ET010:Impact detected.
This status indicates that an impact was detected by the computer.
–ET072:Passenger airbag status indicator light activated.
This status permits a check on the request by the computer for the passenger airbag indicator
light to be lit.
–ET073:Computer locked by tool.
This status indicates that the computer has been locked by the diagnostic tool.
–ET074:Fault warning light activated.
This status permits a check on the request by the computer for the fault warning light to be lit.
–ET076:Computer in need of replacement.
This status indicates whether the computer should be replaced.
–ET108:Passenger airbag locking mode.
This status signals whether the vehicle is fitted with a passenger airbag locking switch.
–ET143:Passenger airbag(s) locked.
This status indicates the passenger trigger line locking (passenger front airbag, passenger front
chest airbag and passenger lap pretensioner).
–ET144:Fault present or stored.
This status indicates if the computer has detected a present or a stored fault.
–ET168:Driver's seat belt contact.
This status is used to check whether the driver buckle switch is working properly.
–ET171:Passenger presence detected.
This status indicates if a passenger has been detected on the front passenger seat.

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.
