CHANGING THE AIR BAG COMPUTER
Air bag computers are sold locked to prevent any risk of incorrect triggering (all trigger lines are
inhibited). This "locked" mode is indicated by illumination of the warning light on the instrument panel.
When changing an air bag computer, follow the instructions below:
- Ensure that the ignition is switched off.
- Change the computer.
- Carry out a check using the fault finding tool.
- If necessary change the computer configuration using the "computer configuration" command
- Unlock the computer, only in the absence of a fault declared by the fault finding tool.

Chart 1NO DIALOGUE WITH THE AIR BAG COMPUTER
NoneNOTES
Ensure that the fault finding tool is not the cause of the fault by trying to communicate with a computer
on another vehicle . If the tool is not at fault and dialogue can be established with another computer on
the same vehicle, it may be that a faulty computer has disrupted the fault finding linesK and L.
Proceed using successive disconnections in order to locate this computer.
Check the battery voltage and carry out the necessary operations to obtain the correct voltage (10.5 volts
< U battery > 16 volts).
When communication is established, deal with any faults which may be declared.
Check the presence and condition of the air bag computer supply fuse.
Check the computer connector connection and the condition of its connections.
Check the the computer is correctly supplied :
- Disconnect the air bag computer and fit the XRBAG 30 track B40 adaptor .
- Check and ensure the presence of the +After Ignition Feed between the terminals marked earth and
+After Ignition Feed .
Check that the diagnostic socket is supplied correctly :
-+Before Ignition Feed ontrack 16.
-Earth on track 5.
Check the continuity and insulation of the diagnostic socket / air bag computer connection lines:
- Between the terminal marked L and track 15 of the diagnostic socket.
- Between the terminal marked K and track 7 of the diagnostic socket .
If dialogue is still not established after carrying out these different checks, replace the air bag computer
(refer to "Aid" section for this operation).

NOTES
Erase the computer memory.
For a micro-cut fault, check the computer supply lines :
- condition of the connections on the computer,
- the condition of the computer earths (tracks 6 and 30 on the 50 track connector to the front right pillar
earth).
- condition/ position of the fuse,
- condition and tightness of the battery terminals.

Carry out the operations necessary to obtain the correct supply voltage for the computer :
9 volts ± 0.1 < correct voltage < 18 volts ± 0.1.
- Check the battery charge.
- Check the charging circuit.
- Check the tightness and condition of the battery terminals.
- Check the computer earth.
