To use this function, enter G on the XR25 , then the number of the command followed by a star.
03Courtesy light control (Illuminates the courtesy light for 3 seconds).
04Forced protection mode : activates the immobiliser function even if the key is correct, which allows
starting prevention to be checked. Bargraph 9 left should illuminate.
This command must be entered when the ignition is off and the immobiliser function is active.
IMPORTANT: switching the ignition off cancels this command.

AIRBAG - SEAT BELT PRETENSIONERS
Fault finding -Introduction
CONDITIONS FOR THE APPLICATION OF THE CHECKS DEFINED IN THIS FAULT FINDING
The checks defined in this fault finding should only be applied to a vehicle when the fault bargraph is
illuminated, indicating that the fault is present on the vehicle at the time of checking. Only a computer
fault will require replacement of the computer, whether the bargraph is permanently illuminated or
flashing .
If the fault is not present but simply memorised, the bargraph flashes and application of the checks
recommended in the fault finding section will not allow the origin of the fault to be found. In this case,
only a check of the wiring and the connection of the component in question must be carried out (it is
possible to test the wiring concerned in fault finding mode to try to obtain permanent illumination of the
bargraph ).
TOOLING REQUIRED FOR OPERATIONS ON THE AIRBAG AND SEAT BELT PRETENSIONER SYSTEMS :
- XR25 (with minimum XR25 cassette N° 16).
- XRBAG the updated N° 3 version (with the new measuring lead and its adaptors as well as the 30 track
adaptor for operations on the computer connector).
REMINDER:
When carrying out an operation on the airbag/seat belt pretensioner systems , it is essential to lock the
computer with the XR25 command G80* to avoid all risk of triggering at the wrong time (all firing lines
will be inhibited). This operating mode will be indicated by illumination of the warning light on the
instrument panel.
Never carry out any measuring operations on the airbag and pretensioners trigger lines with equipment
other than the XRBAG.
Before using a dummy ignition module, ensure that its resistance is between 1.8 and 2.5 ohms.
Only 30 track connector computers with airbag(s) function are able to be tested with the XR25.
Computers with the pretensioner function only must be checked with the XRBAG by following the checks
described in the fault finding section.
The ignition must be switched off, then on again to make the warning light extinguish following erasure
of the memory using the command G0**.

Ensure that 12 volts are reaching the warning light .
If the checks carried out have not proven the existence of a fault, disconnect the computer connector and
fit the 30 track XRBAG adaptor . Use the XRBAG in testing mode to check the operation of the warning
light on the instrument panel from the grey adaptor wire.
If it is possible to illuminate the warning light using the XRBAG, replace the airbag computer (consult
the section "Aid" for this operation).
If it is impossible to operate the warning light , repeat the preceding checks.

Fault present before impact 14
NoneNOTES
This bargraph is normally illuminated in the following situations :
- An impact has been detected.
- A fault was present in the computer memory before the impact.
- This fault was declared by the illumination of the fault warning light before the impact .
Bargraph 14 left hand side can in this way justify non-release of an airbag or a seat belt pretensioner .
Consult the Techline if this bargraph is illuminated in other situations (no fault, no impact, ...).
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*.AFTER REPAIR

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.
