When discarding the seat belt with
pre-tensioner or a vehicle which is equipped with seat
belts with pre-tensioner, be sure to deploy the
pre-tensioner in advance as specified in the
service procedure that follows.
|
|
1.Move the vehicle to flat
and isolated spot.
|
|
2.
caution |
Before starting the work, wait
for 60 seconds or more
after the disconnection of the battery cable.
(Refer to the item 5
of
Service Precautions).
|
Disconnect the (-) and (+) terminals of
battery cable, and then remove
the battery from the vehicle.
|
|
3.Remove the rear pillar
lower trim <Single Cab> (Refer to GROUP 52A -
Interior
Trim ), rear door
lower trim <Club Cab> (Refer to GROUP
52A - Door Trim ), centre

4.Use the flat-tipped
screwdriver to pull out the locking button of floor harness
connector.
After releasing the lock, disconnect the
connector.
note |
When the floor harness
connector is disconnected from the seat belt
pre-tensioner, the
two pins of the seat belt pre-tensioner
connector are automatically shorted. This
prevents the
unintentional deployment of the seat belt
pre-tensioner caused by the static or
others.

|
5.Connect the deployment
wires of 6 m or more to each of the two wiring harnesses of
special
tool adapter harness (MB991885), and cover the connection
areas with insulation tape. Keep the
other ends of deployment wires connected to each other
(shorted).
note |
This prevents the
unintentional deployment of seat belt
pre-tensioner caused by the static
or others.

|
6.Connect the adapter
harness (MB991885) to the 2-pin connector of seat belt
pre-tensioner,
and then pull out the deployment wire to outside the
vehicle. 7.In order to suppress the operation
sound as much as possible, fully close all the
door windows and close the doors. 8.
caution |
- Make sure that no one
is present inside or near the vehicle
before the deployment.
- Immediately after the pre-tensioner
deployment, the inflator is extremely
hot. Thus,
before handling, leave the inflator for
30 minutes or more to cool.
- If the seat belt pre-tensioner does not
deploy, consult with your
distributor.
|
Disconnect the deployment wire connection at a place
as far as possible from the vehicle.
Then, connect the wires to the removed vehicle battery to
deploy the seat belt pre-tensioner. 9.Discard the
deployed seat belt pre-tensioner according to the disposal
procedures
(Refer to ).

connector.
note |
When the floor harness
connector is disconnected from the lap
pre-tensioner, the two pins
of pre-tensioner connector are automatically
shorted. This prevents the unintentional
deployment
of lap pre-tensioner caused by the static or
others.

with pre-tensioner according to the disposal procedures
(Refer to ).
|
|
After deployment and operation, the
air bag module and seat belt pre-tensioner should
