AIRBAG - SEAT BELT PRETENSIONERS 
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.

AIRBAG - SEAT BELT PRETENSIONERS 
Fault finding - Aid
REPLACING THE AIRBAG COMPUTER
The  airbag computers   are sold in locked mode to avoid all risk of release at the wrong time (all
trigger lines are inhibited). This operational mode is indicated by the illumination of the warning
light on the instrument panel.
When replacing the airbag computer, follow this procedure :
- Ensure that  the ignition is switched off.
- Replace  the computer.
- Carry out an XR25 check.
- Unlock the computer using  command G81*, only when no fault is declared.
