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**.
