Never carry out measurements on the trigger lines with equipment other than the
XRBAG. On this vehicle "line 1" corresponds to the single trigger line of the
passenger’s airbag module .
NOTES
Lock the computer using command G80* on the XR25.
Switch off the ignition, disconnect the computer connector and fit the 30 track adaptor.
The XRBAG tool MUST be used for checking resistance on the wire marked C on the adaptor.
Is the value obtained correct?
Reconnect the computer and the ignition module of the passenger’s airbag module , then switch on the
ignition again.
Carry out an XR25 check.
If the kit still indicates the presence of a line 1 passenger’s airbag fault and and the checks carried out
show no evidence of a fault, replace the airbag computer (consult the section "Aid" for this operation).
If the value obtained is correct at wire C on the adaptor, check the condition of the
computer connection .YES
If the value obtained is not correct at wire C on the adaptor, check the 30 track
connector connection (tracks 6 and 7).NO
If the value remains incorrect, switch off the ignition and remove the dashboard to
gain access to the wiring of the passenger’s airbag module . Disconnect the ignition
module of the passenger’s airbag module, connect a dummy ignition module to the
ignition module , then use the XRBAG to measure the resistance on the wire marked C
on the adaptor.
If the value obtained is correct , replace the passenger’s airbag module .
If the value obtained is not correct, replace the airbag wiring.
Erase the computer memory using the command G0** then switch off the ignition.
Carry out another XR25 check and if there is no fault, unlock the computer using
command G81*.
Destroy the airbag cushion if it has been replaced (tool Elé. 1287).

If the value remains incorrect , replace the airbag wiring.
Lock the computer using command G80* on the XR25.
Switch off the ignition, disconnect the computer connector and fit the 30 track adaptor.
The XRBAG tool MUST be use for measuring insulation appropriate to the type of fault on the wire
marked C on the adaptor.
Is the value obtained correct? ?
