Land Rover Body And Paint Air Bag And Safety Belt Rover Manual

PASSENGER AIR BAG
DEACTIVATION SWITCH (ALL
EXCEPT NAS)
The passenger air bag deactivation switch provides a
method of manually disabling the passenger air bag.
The switch is installed in the front passenger end of the
instrument panel and operated by the ignition key.
When the passenger air bag deactivation switch is
operated, it changes a ground connection between two
pins in the connectors of the restraints control module.
When the passenger air bag deactivation switch is
selected to OFF, the...

The occupant detection system can only determine if
the front passenger seat is occupied or unoccupied. The
occupant detection system consists of a pressure sensor
installed between the foam padding and the cover of the
front passenger seat cushion.
The pressure sensor incorporates a number of load cells
connected in series and embedded in a plastic film.
Weight on the pressure sensor increases the resistance
of the circuit.
The instrument cluster supplies a reference voltage to
the pressure sensor and...

Occupant classification module6
The occupant classification system can determine if the
front passenger seat is unoccupied, occupied by a small
person, or occupied by a large person. The occupant
classification system consists of:
•A pressure pad, installed under the cushion of the
front passenger seat, which is connected to a pressure
sensor.
(G421346) Technical Training266...

•A safety belt tension sensor, integrated into the
anchor point of the front passenger safety belt.
•An occupant classification module, installed under
the front passenger seat.
The pressure pad is a silicone filled bladder. Any load
on the pressure pad is detected by the pressure sensor.
The safety belt tension sensor is a strain gauge that
measures the load applied by the safety belt anchor to
the anchor bolt.
The occupant classification module supplies a reference
voltage to the pressure sensor and...

AIR BAG WARNING INDICATOR
The air bag warning indicator consists of a red Light
Emitting Diode (LED) behind a SRS graphic in the
tachometer of the instrument cluster.
Operation of the air bag warning indicator is controlled
by a high speed CAN bus message from the restraints
control module to the instrument cluster. The restraints
control module illuminates the air bag warning indicator
if a fault is detected, and for approximately 6 seconds
during the bulb check at the beginning of each ignition
cycle....

The clockspring consists of a plastic cassette which
incorporates an outer cover fixed to the steering column
and an inner rotor which turns with the steering wheel.
Four securing lugs attach the cover to the multifunction
switch on the steering column. The rotor is keyed to the
steering wheel by a drive peg. A lug on the underside
of the rotor operates the self-cancelling feature of the
turn signal indicator switch. A ribbon lead, threaded on
rollers in the rotor, links two connectors on the cover
to...
