NOTESIf 1.DEF, check and modify the computer configuration.
Special notes:
Depending on the vehicle bodywork definition, this fault relates to a fault on the lap
belt pretensioner circuit or the seat base airbag (anti-submarine airbag).
Never take measurements on the ignition lines with any tool other than the CLIP
or XRBAG tool.
Use the 64-track adapter Elé. 1717 when working on the computer connector
and use the 8-track adapter Elé. 1617 when working on the seat.

NOTESCorrect the configuration of the ignition lines if the vehicle is
not fitted with a driver's lap belt/seat base airbag.
Lock the computer using the diagnostic tool.
Disconnect the computer connector and fit the 64-track adapter Elé. 1717.
The CLIP or XRBAG tool must be used to measure the resistance on the adapter cable marked B.
If the value indicated is correct, check the connections of the 64-track connector (tracks 3 and 4).
Check the connections of the 8-track connector under the seat.
Repair if necessary.
Fit the 8-track test adapter Elé. 1617 underneath the seat (point C1).
The CLIP or XRBAG tool must be used to measure the resistance on cable D.
Is the value obtained correct?
AFTER REPAIRReconnect the computer and driver's seat base/lap airbag ignition module, then switch
on the ignition again. Clear 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.
When replacing the airbag module, do not forget to reconnect the earth on the new
module.
Destroy the driver's seat base airbag module or the lap belt pretensioner if they have
been replaced (tool Elé. 1287).
