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.

5.2 Connector check
Visual inspection of the connection:
– Check that the connector is connected correctly and that the male and female parts of the connection are correctly
coupled.
Visual inspection of the area around the connection:
– Check the condition of the mounting (pin, strap, adhesive tape, etc.) if the connectors are attached to the vehicle.
– Check that there is no damage to the wiring trim (sheath, foam, adhesive tape, etc.) near the wiring.
– Check that there is no damage to the electrical wires at the connector outputs, in particular on the insulating material
(wear, cuts, burns, etc.).
Disconnect the connector to continue the checks.
Visual inspection of the plastic casing:
– Check that there is no mechanical damage (casing crushed, cracked, broken, etc.), in particular to the fragile
components (lever, lock, openings, etc.).
– Check that there is no heat damage (casing melted, darker, deformed, etc.).
– Check that there are no stains (grease, mud, liquid, etc.).Note:
Carry out each requested check visually.
Do not remove a connector if it is not required.
Note:
Repeated connections and disconnections alter the functionality of the connectors and increase the risk of poor
electrical contact. Limit the number of connections/disconnections as much as possible.
Note:
The check is carried out on the 2 parts of the connection. There may be two types of connection:
– Connector/Connector.
– Connector/Device.

CONFIGURATION/CONFIGURATION READING
– The configuration reading commands are used to read the computer configuration status in relation to the trigger
lines installed in the vehicle.
PARAMETER SETTINGS:
LOCK COMPUTER
This command should be used for any operation on the system. It inhibits all of the trigger lines.
UNLOCK COMPUTER
This command is used to unlock the computer when it is new or if it has been deactivated via the UNLOCK
COMPUTER command.Configuration reading Option Configuration

REPLACING THE AIRBAG COMPUTER
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 indicator light on the instrument panel illuminates.
Follow this procedure when replacing an air bag computer:
– Make sure the ignition is switched off.
– Replace the computer (see MR Mechanical: MR-AIRBAGS-SRP, 88, Airbags and seat belt pretensioners,
Computer: Removal-refitting).
– Carry out a check using the diagnostic tool.
– If necessary, modify the computer configuration using the "Configuration" command.
– Switch off the ignition.
– Unlock the computer only if no faults are indicated by the diagnostic tool.
WARNING:
The owner of the vehicle may have locked the passenger front airbag to allow a child seat to be fitted to
the front passenger seat. In this case, the procedure for locking the passenger front airbag defined in the
Technical Note published for this subject has been applied, i.e.:
– Signing of a discharge by the customer (example in the Technical Note).
– Replacement of the passenger front seat belt.
– Disconnection of the passenger front airbag module.
– Locking of the trigger line of the passenger front airbag and modification of the computer configuration.
– Replacement of the "airbag" labels on the passenger side.
If this procedure has been applied, it is imperative to relock the passenger front airbag using the "Lock
passenger front airbag" command ("Configuration and programming" section).
It is vital that you never use this passenger airbag locking command before a Technical Note dealing with
the subject has been distributed.
