Check procedure
Apart from the following items, servicing is the same as in the previous
model.
Clock spring
If any of the following checks reveals a non-conformity, then the clock
spring must be replaced with a new one.
(1)
Damage to the connectors or protector tube, or deformation of
the terminals
(2)
Damage to the case
(3)
Check that there is connectivity between the C-205 clock spring
connector terminal 1 and the C-206 phone switch connector.
(4)
(Vehicle with integrated airbag module)
Insert the special probe (MB991222) behind the Driver’s airbag
module connector C-207.
Caution
Do not insert the probe directly into the terminal from the
front side of the connector.
(5)
Connect the circuit tester to the special tool, as illustrated in the
diagram, and check that there is connectivity between the
terminals.
(4)
(Vehicle with separate airbag module)
Align the paint mark of the No.1 connector of the special SRS
check harness (MB991606 or MB991613) with the arrow on the
No.3 connector of the clock spring. Couple the connectors
together.
(5)
(Using SRS check harness (MB199606))
Check that there is connectivity between the terminals 25 – 26 of
the No.2 connector of the SRS check harness.
(Using SRS check harness MB991613)
Check that there is connectivity between the terminals 22 – 23 of

Seat belt Pre-Tensioner
Apart from the following items, servicing is the same as for the previous
model.
Removal service points
Removal of seat belt pre-tensioner
Using a flathead screwdriver, pull the locking button of the harness side
connector two steps towards you, release the lock and remove the
connector.
Disposal procedures for airbag module and seat belt pre-tensioner
When disposing of an airbag module or seat belt pre-tensioner, or when disposing of a vehicle fitted with airbag modules and
seat belt pre-tensioners, the following procedures must be observed so that the airbag module and/or pre-tensioner are
actuated before disposal.
Disposal of airbag module
Apart from the deployment harnesses shown below which are used to deploy the driver’s airbag module in the vehicle,
servicing information is the same as that for the previous model.
• Deployment harness
(1) Prepare two deployment harnesses at least 6m long, and connect
together (short) the terminal sections on either side. This will prevent
accidental deployment of the driver’s airbag due to static electricity,
etc.
(2) Touch the vehicle body with your bare hand to eliminate any
accumulated static electricity.
Caution
The procedure above is designed to prevent malfunction due to
static electricity, and must be carried out in all cases.
(3) Detach the clock spring connector C-204.
(4) Using a clipper, or the like, cut the instrument panel wiring harnesses
as illustrated in the diagram.
Remarks
In this step, the harnesses should be cut at a sufficient distance from
the clock spring connector, taking into account the connection position
of the deployment harnesses.
(5) Connect the deployment harnesses respectively to the two cut
harnesses, and seal the connected sections with insulating tape. Trail
the deployment harnesses outside of the vehicle.
(6) Take the connector which is coupled to the deployment harnesses, and
connect it to the clock spring connector C-204.

connector two steps towards you, release the lock and remove the
connector.
• Pre-tensioner adapter harness
When actuating the pre-tensioner, both inside and outside the vehicle, a
