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).
3. PREREQUISITES FOR FAULT FINDING

Check that it is correctly connected.
Disconnect the steering wheel airbag and connect a dummy ignition module to the ignition module connector.
Switch on the ignition and carry out a check using the diagnostic tool.
Replace the airbag if the fault is now stored (fault no longer declared as present) (see MR Mechanical: MR-
AIRBAGS-SRP, 88, Airbags and seat belt pretensioners, Driver's airbag: Removal-refitting).
With the ignition switched off, disconnect and reconnect the connector of the rotary contact beneath the steering
wheel.
Check the connections if the fault has become stored (fault no longer declared present).
