1.DEF: Configuration
NOTESIf 1.DEF, check and modify the computer configuration.
Priorities when dealing with a number of faults: If DF068 is present with at least
one of faults DF210 or DF241, begin the fault finding by checking the 22-track under-
seat connector.
Special notes: never carry out measuring operations on trigger lines using any tool
other than CLIP or XRBAG.
Use the 64-track adapter (Elé. 1717) when working on the computer connector,
and use the 22-track adapter (Elé. 1687) when working on the seat connector.
CO - CC
NOTESSpecial notes: correct the trigger line configuration if the
vehicle is not fitted with passenger front chest-level side
airbags.
Lock the computer, 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 F.
If the value obtained is correct, check the connections of the 64-track (tracks 43 and 44) connector.
Check the connections of the 22-track connector under the seat. Repair if necessary. Fit the 22-track test adapter
(Elé. 1687) underneath the seat (point C1).
The CLIP or XRBAG tool must be used to measure the resistance on cable A.
Is the value obtained correct?
NO
YES
Check the seat connector connections (tracks 11 and 12).
Strip the passenger seat and check that the side airbag module ignition module is connected correctly.
Disconnect the side airbag ignition module, connect a dummy ignition module to the ignition module
connector and measure the resistance on cable A again.
– If the value obtained is correct, replace the passenger's front chest side airbag module.
– If the value obtained is still not correct, replace the wiring between points C1 and C3 (seat wiring).
Check the seat connector connections again (tracks 11 and 12) as well as those of the 64-track
connector (tracks 43 and 44).
If the fault persists, the wiring is faulty between the computer and the passenger's seat (C0/C1).
Replace the wiring if necessary.
AFTER REPAIRReconnect the computer and the ignition module of the passenger's front side airbag
module then switch on the ignition again. Clear the computer memory then switch off
the ignition.
