1. SCOPE OF THIS DOCUMENT
This document presents the fault finding method applicable to all computers with the following specifications:
2. CONDITIONS FOR APPLICATION OF THE TESTS DEFINED IN THIS FAULT FINDING
The tests defined in this fault finding should only be applied to vehicles not fitted with side airbags but which are
fitted with the 2nd generation of airbag computers.
These new computers can be identified by the heading AC4 Ph 2 on the fault finding tools.
The tests defined in this fault finding must only be carried out if the fault is present on the vehicle at the time the test
is carried out.
Only the computer fault leads to replacement of the computer, whether the fault is present or simply stored.
If the fault is not present but simply stored, applying the checks recommended in the fault finding will not allow the
reason why this fault was stored to be located. In this case only, the wiring and the faulty component connections
should be checked (it is possible to access the wiring concerned in fault finding mode to try to display the change
from stored fault to present fault).

4. REMINDERS
During operations on the airbag/seat belt pretensioner systems it is vital that you lock the computer using the
diagnostic tool to prevent any risk of accidental triggering (all the trigger lines will be inhibited). The locked mode is
indicated when the instrument panel warning light comes on. Without the diagnostic tool, switch off the ignition and
remove the supply fuse from the system, then wait at least 2 seconds for the power reserve capacity to discharge.
Never measure the airbag or pretensioner trigger lines with any device other than the XRBAG or by the "Airbag and
pretensioner wiring harness check" function on the CLIP and NXR tools.
Before using a dummy ignition module, check that its resistance is between 1.8 and 2.5 ohms.
Ensure during the operation that the supply voltage to the computer does not drop below 10 volts.Special tooling required
Diagnostic tools (except XR25)
Adapter and bornier kit to be used for the "Airbag and
pretensioner wiring harness check" function of the CLIP and
NXR tools or the XRBAG unit.
