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.

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.
