Fault finding – Replacement of components
REPLACING A SYSTEM COMPONENT
Disconnect the battery before removing and refitting any pyrotechnic component (airbag module,
pretensioner or seat belt retractor).
REPLACING THE AIRBAG COMPUTER
BEFORE REPLACING THE COMPUTER IT IS ESSENTIAL THAT YOU CONTACT THE TECHLINE.
To ensure that the returned computer's fault can be analysed, do not use command RZ001 "Fault memory"
when DF001 "Computer" is present or stored.
The airbag computers are sold in locked mode to avoid all risk of accidental triggering (all ignition lines are inhibited).
The "locked" mode is indicated when the airbag fault warning light on the instrument panel illuminates.
Follow this procedure to replace an airbag computer:
– check that the ignition is switched off,
– replace the computer,
– modify the computer configuration if necessary,
– write the VIN to the computer using the diagnostic tool command VP010 Write VIN,
– switch off the ignition,
– carry out a check using the diagnostic tool,
– unlock the computer using the command VP007 Unlock computer, only if there are no faults declared by the
diagnostic tool and check that the warning light has gone out.
After the computer has been replaced, if there are abnormalities on the impact sensors, it is necessary to check that
the sensors fitted are compatible with the airbag computer connected to the vehicle. If not, it is necessary to order
the sensors which are specifically for the respective airbag.
Note:
After the airbag computer is replaced, if the engine no longer starts, restore the injection operation by applying the
following procedure:
– Run command RZ001 to clear the faults from the injection computer memory (even if no present or stored faults
are declared).
– Switch off the ignition and wait for loss of dialogue with the injection computer.
–Drive for 1 minute at a speed greater than 21 mph (35 km/h) to restore the operation of the steering column
lock.

NOTESNone.
Lock the computer using the diagnostic tool.
Switch off engine and remove the glovebox.
Disconnect the 8-track intermediate connector from the passenger air bag and check the connections (tracks A5
and A6 behind the glove box).
Fit the 8-track test adapter Elé. 1617.
The CLIP or XRBAG tool must be used to measure the resistance on the adapter cable B.
Is the value obtained correct?
YES
Reconnect the 8-trackconnector.
Disconnect the computer and check the connector connections (tracks 1 and 12).
Fit the 22-track adapter Elé. 1685.
The CLIP or XRBAG tool must be used to measure the resistance on the adapter
cable A.
If the value obtained is incorrect, the wiring is faulty between the computer and the
8-track connector (C0/C2).
Repair or replace the wiring harness if necessary.
NOCheck that the passenger airbag ignition module (GREEN) connector is correctly
connected.
Disconnect the GREEN passenger airbag connector, connect 1 dummy ignition module
to the ignition module connector and check the resistance again on the cable B.
– If the value obtained is correct, replace the passenger airbag.
– If the value obtained is incorrect, the wiring is faulty between points C2 and C4.
Repair or replace the wiring harness if necessary.
AFTER REPAIRReconnect the computer and driver's frontal airbag ignition modules, then switch on
the ignition again.
Clear the computer fault memory. Switch off the ignition.
Carry out the check again using the diagnostic tool and, if there is no fault, unlock the
computer. When replacing the airbag module, do not forget to reconnect the earth on
the new module.
Destroy the driver's front airbag if it has been replaced (tool Elé. 1287).
