DRIVER'S CHEST FRONT SIDE AIRBAG CIRCUIT
CC : Short circuit
CO : Open circuit
CC.1 : Short circuit to + 12 V
CC.0 : Short circuit to earth
1.DEF : Configuration
NOTESIf 1.DEF, check and adjust the computer configuration.
Priorities when dealing with multiple faults: If DF077 is present with at least one of
DF065, DF210, DF232, or DF240, 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 (Elé. 1717) adapter for working on the computer connector and the
22-track (Elé. 1687) adapter for working on the seat.
CO - CC
NOTESSpecial notes: correct the trigger line configuration if the
vehicle is not fitted with a driver's front chest side airbag.
Lock the computer, disconnect the computer connector and attach 64-track adapter (Elé. 1717). The CLIP or
XRBAG tool absolutely must be used to measure the resistance in the adapter cable marked H.
If the value indicated is correct, check the connections of the 64-track (tracks 15 and 16) connector.
Check the connections of the 22-track connector under the seat. Repair if necessary. Attach the 22-track
(Elé. 1687) test adapter under the seat (point C1).
The CLIP or XRBAG tool absolutely must be used to measure the resistance in cable A.
Is the value obtained correct?
NO
YES
Check the seat connector connections (tracks 11 and 12).
Remove the trim from the driver's seat and check that the chest side airbag ignition module is properly
connected.
Disconnect the chest side airbag ignition module, connect a dummy ignition module to the ignition
module connector and again measure the resistance in cable A.
– If the value obtained is correct, replace the driver's chest front 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 (tracks 11 and 12) again, as well as those of the 64-track
(tracks 15 and 16) connector.
If the fault is still present, the wiring is faulty between the computer and the driver's seat (C0/C1).
Replace the wiring if necessary.
AFTER REPAIRReconnect the computer and the ignition module of the driver's front side airbag
module then switch on the ignition. Clear the computer memory then switch off the
ignition.
Carry out the check again using the diagnostic tool and, if there are no faults, unlock
the computer. When replacing the airbag module, do not forget to reconnect the earth
on the new one.
Destroy the chest side airbag module if it has been replaced (tool Elé. 1287).
