Use bornier Elé. 1332 for any operations on the computer connector.NOTES
When communication is established, deal with any fault bargraphs which may be
illuminated.
Ensure that the XR25 is not the cause of the fault by trying to communicate with the computer on ano-
ther vehicle. If the XR25 is not the cause of the fault and dialogue is not established with another compu-
ter on the same vehicle, a faulty computer may be causing interference on the K and L fault finding lines.
Disconnect connections successively to determine which computer is at fault.
Check the ISO selector is on position S8, that you are using the latest XR25 cassette and the correct access
code (D34).
Check the battery voltage and carry out any necessary operations to ensure the correct voltage (U battery
> 10.5 volts).
Check the 15 Amp fuses on the engine connection unit have not blown (positions 3 and 4).
Check the connection and condition of the connections on the computer connector and the connection
R67 engine / dashboard.
Check the computer is correctly fed:
- Earth on track 2 of the computer connector (check the condition and tightness of the engine earth
strap and the engine earth MH near to the gearbox housing).
- + after ignition feed on track 1 of the computer connector.
Check the diagnostic socket is correctly fed:
- Earth on track 5.
- + before ignition feed on track 16.
Check and ensure the continuity and insulation of the lines in the connection diagnostic socket/
computer:
- Between track 10 of the computer connector and track 15 of the diagnostic socket.
- Between track 13 of the computer connector and track 7 of the diagnostic socket.
If fault finding is not established after these operations, replace the computer (consult the "Aid" section
for this operation).

Ensure insulation in relation to 12 volts of the connection between track 19 on the computer connector
and track 18 on the air conditioning computer connector.
Test the connections on the 2 connectors (+ intermediate connection engine / dashboard).
Even if present at the moment of testing, this fault is still declared
by a flashing BG 13LH side. To confirm its presence and the necessity
of following the fault finding below, erase the computer memory
then start the engine. The fault is present if the bargraph flashes
when the engine is running.
NOTES
If the fault persists after these tests, replace the air conditioning control module.
If the "air conditioning cut out information "fault reappears, replace the diesel injection computer (consult
the "Aid" section for this operation).

Check that the XR25 kit is not the cause of the fault by trying to communicate with the computer of
another vehicle. If the XR25 kit is not at fault and it will not communicate with any other computer in the
same vehicle, it is possible that a faulty computer is corrupting fault finding lines K and L . Locate this
computer by disconnecting the lines one by one.
Check that the ISO interface is correctly in position S8 and that you are using the most recent XR25
cassette and the correct access code.
Check the battery voltage and carry out the necessary operations to obtain the correct voltage(9.4Volts<
U battery<17.4Volts)
Check the presence and condition of the ABS fuse on the connection unit of the passenger compartment
(10A).
Check the connection of the computer connector and the condition of its connection.
Check the connection and condition of the connection at the R36 dashboard / ABS connection.
Check the ABS earth wires (tighten the two earth screws above the ABS assembly).
Check that the computer is correctly fed :
-earth on track 19 of the 31 track connector,
-+ after ignition feed on track 15 of the 31track connector.
Check that the diagnostic socket is correctly fed :
-+ before ignition feed on track 16,
-earth on track 5.
Check the continuity and insulation of the lines in the diagnostic socket / ABS computer connection:
- between track 12 of the computer connector and track 15 of the diagnostic socket,
- between track 11 of the computer connector and track 7 of the diagnostic socket.
If dialogue is still not established after these tests, replace the ABS computer.,

- +after ignition on track 15 of the 31 track connector.
Ensure that the XR25 is not at fault by trying to communicate with a computer on another vehicle. If the
XR25 is not at fault and dialogue is not being established with another computer on the same vehicle, it is
possible that a faulty computer is disturbing diagnostic lines K and L. Proceed with successive disconnec-
tions to localise this computer.
Check that the ISO interface is in position S8, that you are using the most recent version of the XR25 kit
and the correct access code.

Never carry out measurements on the trigger lines with equipment other than the
XRBAG. On this vehicle "line 1" corresponds to the single trigger line of the
passenger’s airbag module .
NOTES
Lock the computer using command G80* on the XR25.
Switch off the ignition, disconnect the computer connector and fit the 30 track adaptor.
The XRBAG tool MUST be used for checking resistance on the wire marked C on the adaptor.
Is the value obtained correct?
Reconnect the computer and the ignition module of the passenger’s airbag module , then switch on the
ignition again.
Carry out an XR25 check.
If the kit still indicates the presence of a line 1 passenger’s airbag fault and and the checks carried out
show no evidence of a fault, replace the airbag computer (consult the section "Aid" for this operation).
If the value obtained is correct at wire C on the adaptor, check the condition of the
computer connection .YES
If the value obtained is not correct at wire C on the adaptor, check the 30 track
connector connection (tracks 6 and 7).NO
If the value remains incorrect, switch off the ignition and remove the dashboard to
gain access to the wiring of the passenger’s airbag module . Disconnect the ignition
module of the passenger’s airbag module, connect a dummy ignition module to the
ignition module , then use the XRBAG to measure the resistance on the wire marked C
on the adaptor.
If the value obtained is correct , replace the passenger’s airbag module .
If the value obtained is not correct, replace the airbag wiring.
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*.
Destroy the airbag cushion if it has been replaced (tool Elé. 1287).
