Never carry out measurements on the trigger lines with equipment other than the
XRBAG.NOTES
Lock the computer using command G80* on the XR25.
Switch off the ignition and check that the ignition module of the passenger’s pretensioner is correctly
connected.
Disconnect the ignition module of the passenger’s pretensioner and connect a dummy ignition module
to the ignition module connector.
Switch on the ignition and carry out an XR25 check.
Replace the passenger’s pretensioner if the fault has been memorised (fault no longer declared).
Disconnect the computer connector and fit the 30 track adaptor.
The XRBAG tool MUST be used for checking resistance on the wire marked D on the adaptor.
If the value obtained is not correct , check the 30 track connector connection (tracks 3 and 4) and replace
the wiring if necessary.
If the checks carried out have not proven the existence of a fault, replace the airbag computer (consult
the section "Aid" for this operation).
Reconnect the ignition module of the passenger’s pretensioner .
The XRBAG tool MUST be used for checking resistance at point C1 (seat connector) of the passenger’s
pretensioner line.
If the value obtained is not correct , replace the wiring between points C1 and C3 (seat 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 pretensioner if it has been replaced (tool Elé. 1287).

Never carry out measurements on the trigger lines with equipment other than the
XRBAG.NOTES
Lock the computer using command G80* on the XR25.
Disconnect the ignition module of the driver’s pretensioner and connect a dummy ignition module to
the ignition module connectors.
Switch on the ignition and carry out an XR25 check.
If the fault has been memorised (fault no longer declared), check the condition of the seat wiring.
Replace the driver’s pretensioner if the wiring is not faulty.
Then carry out the same operation on the Passenger’s pretensioner (if not a driver’s side fault ).
The XRBAG tool MUST be used for measuring insulation appropriate to the type of fault at point C1 (seat
connector) of the driver’s pretensioner line.
If the value obtained is not correct , replace the wiring between points C1 and C3 (seat wiring).
Then carry out the same measurement on the passenger’s pretensioner line (if not a driver’s side fault ).
Disconnect the computer connector and fit the 30 track adaptor.
The XRBAG tool MUST be used for measuring insulation appropriate to the type of fault on the adaptor
wires marked D (Passenger ) and E (Driver ) .
If one of the values obtained is not correct, check the 30 track connector connection (tracks 3 / 4 for wire
D and 1/2 for wire E) and replace the wiring if necessary .
If the checks carried out have not proven the existence of a fault, replace the airbag computer (consult
the section "Aid" for this operation).
Reconnect the ignition modules of the seat belt pretensioners.
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 pretensioner(s) if it has been replaced (tool Elé. 1287).

Fault finding - Pretensioner Check
Destroy the pretensioner(s) if it has been replaced (tool Elé. 1287).AFTER REPAIR
Seat belt pretensioner circuit check
on computer without airbag function
NoneNOTES
The XRBAG tool MUST be used for checking resistance and tests for leaks to positive and to earth on the
adaptor wires marked D and E .
If the values obtained on the 2 circuits are correct,there is no fault on the seat belt pretensioner circuit.
Reconnect the computer .
If one of the values obtained is not correct, check the 30 track connector connection (tracks 3 / 4 for wire
D and 1/2 for wire E) and replace the wiring if necessary .
The XRBAG tool MUST be used for checking resistance and tests for leaks to positive and to earth at
point C1 of the pretensioner at fault (wire D : Passenger and E : Driver ).
If all values obtained are correct, replace the wiring between points C0 and C1, then carry out the test
again using the adaptor to check that the repair has been successful.
The XRBAG tool MUST be used for checking resistance and tests for leaks to positive and to earth at
point C3 ( Pretensioner ignition module ).
If all values obtained are correct, replace the wiring between points C1 and C3 (seat wiring), then carry
out the test again at the adaptor to check that the repair has been successful.
If one of the values is not correct at C3, replace the seat belt pretensioner, then carry out the test again
using the adaptor to check that the repair has been successful.
With the ignition switched off, disconnect the computer connector and fit the 30 track XRBAG adaptor.
Switch on the ignition and check the computer power supply between the terminals marked earth and
+after ignition feed.
Carry out the operations necessary to ensure a voltage between 10.5 volts and 16 volts.
