After deactivating the air bag function using the
fault finding tool and removing the passenger air
bag module :
• cut the passenger air bag wiring 60 mm from
the instrument panel wiring tape,
• unsheath the passenger air bag supply wiring
by 30 mm,
• strip the wiring provided in the kit and the
passenger air bag wiring by approximately10
mm,
• thread 2 cm of heat shrink sleeving (provided
in the kit) on each of the vehicle’s wiring lines,
• solder the vehicle’s wiring to the wiring in the
kit (B),
• position the heat shrink sleeving over the sol-
dered joins and heat it,

• refit and secure the passenger air bag module,
• connect the new connector to the passenger
air bag module,
• carry out a check using the fault finding tool.
Unlock the computer if everything is correct,

IMPORTANT : before removing the air bag cus-
hion, lock the computer using the fault finding
tool.
When this operation is activated, all the trigge-
ring lines are inhibited, the air bag warning light
on the instrument panel is illuminated.
ROTARY SWITCH
The rotary switch ensures the electrical connec-
tion between the steering column and the stee-
ring wheel.
It consists of a strip with two conducting tracks
(air bag) of which the length is long enough to al-
low 2.5 turns of the steering wheel (full lock plus
safety) for each side.
Removal
IMPORTANT:The pyrotechnic systems (pretensio-
ners or air bags) must not be handled when near a
heat source or a flame because there is a risk that
the system will be triggered.
IMPORTANT : When removing the steering wheel,
the air bag connector must be disconnected (D)
(see below). The air bag is fitted with a connector
which short circuits when it is disconnected to
avoid incorrect triggering .
14036R1
Remove :
- the air bag cushion by its two torx bolts located
behind the steering wheel and disconnect its
connector (D).
- the steering wheel bolt,
- the steering wheel after positioning the wheels
straight,
- the half cowlings (three bolts).
Disconnect the stalks (windscreen wipers and
lights) and the rotary switch connector.
Before removing the assembly, the rotary switch
position must be noted:
- by ensuring that the wheels are straight during
removal in order to position the length of the
strip in the centre ,
- by checking that the mark "0" is correctly posi-
tioned opposite the fixed index (E).

Special case : the connector with lugs
A series of vehicles are fitted with a red connector
with lugs (A) on the passenger air bag module.

To disconnect it, carefully use a small screwdriver
as a lever , so as not to damage the lugs .
In the event of the lugs breaking, replace the
connector using the kit part number : 77 01 206
210 using the following method.

Reconnect the computer and the driver’s side air bag ignition module, then switch
on the ignition. Erase the computer memory then switch off the ignition.Carry
out a check using the fault finding tool and, in the absence of a fault, unlock the
computer . Destroy the side air bag module if there has been a replacement (tool
Elé. 1287).
Driver’s side air bag circuit
CC : Short circuit
CO : Open circuit
CC.1 : Short circuit to 12 volts
CC.0 : Short circuit to earthDF008
present
NOTESNever carry out measuring operations on the trigger lines with equipment other
than the XRBAG.
NoneNOTES CO - CC
Lock the computer using the fault finding tool command.
The XRBAG must be used for resistance measurements appropriate to the type of fault at point C1 (seat
connector) on the driver’s side air bag module line.
Is the value obtained correct?
Disconnect the computer connector and fit the 50 track B50 adaptor.
The XRBAG must be used to measure resistance on adaptor cable E
If the value obtained is not correct, check the connections on the 50 track connector
(16 and 17) and replace the wiring if necessary
If the value obtained is correct at adaptor cable E, check on the air bag computer base
for the 7 shunt opening pins for the 50 track connector.
Check the condition of the computer connections
Check the condition of the 50 track connector (locking system, connector,...).
YES
Check the connections on the seat connector.
Strip the driver’s seat and check that the side air bag ignition module is connected
correctly .NO
Disconnect the driver’s side air bag ignition module, connect a dummy ignition
module to the ignition module connector and measure the resistance with the XRBAG
onpoint C1 again.
If the value obtained is correct, replace the driver’s side air bag module.
If the value obtained is still incorrect, replace the wiring between points C1 and C3
(seat wiring).
Check the connections on the seat connector (point C1).
Visually check the seat wiring. Reconnect point C1.
