RCM (Restraint Control Module)
E135477
Electronic sensors are incorporated into the RCM;
these measure the vehicle acceleration /
deceleration in the event of a collision. The
calculated value is evaluated by the RCM to
determine the severity of the impact.
The RCM compares the values it receives from the
crash sensor, side impact sensors and the internal
electronic sensors. If the deceleration, due to a
frontal or side impact, exceeds the stored value
the RCM will trigger the air bag modules and the
safety belt pretensioners as required. The RCM
can be used again after a collision, provided the
RCM is not physically damaged and it passes a
self-test.
Passenger air bag deactivation switch
E135479
When the ignition is switched on, a warning lamp
in the instrument panel indicates that the passenger
air bag module has been deactivated.
Air bag warning indicator
E135478
The airbag warning indicator is active when an
airbag system Fault has occurred or the airbag
module is disconnected. The indicator will have a
predetermined bulb prove- out following ignition
being turned to 'Run' configurable with restraints
system.

DESCRIPTION AND OPERATION
Driver air bag and driver lower air bag
E135480
This vehicle line is available with a steering wheel
mounted driver air bag and a driver lower air bag
(knee air bag).
Side impact sensors
1. Side impact sensor (Front doors)
E135481
There are two side impact sensors located in the
front driver and passenger doors. The sensors
transmit digitally encoded pressure information to
the RCM, where it is evaluated to assess the
severity of a side impact. Power is supplied to the
sensor by the RCM. If the sensor fails, the RCM
stores a diagnostic trouble code (DTC).
2. Side impact sensor (Rear side)
E135483
There are two side impact sensors located at the
bottom of the C-pillars in stretch cab and double
cab variants. The sensors transmit digitally
encoded acceleration information to the RCM,
where it is evaluated to assess the severity of a
side impact. Power is supplied to the side impact
sensor by the RCM. If the senor fails, the RCM
stores a diagnostic trouble code (DTC).
Side air curtain
E135482
In the event of a side impact, the side air curtains
(curtain air bags) deploy from the headliner,
protecting the first and second row outboard
occupants during a side impact.
501-20B-11
Supplemental Restraint System
501-20B-11
DESCRIPTION AND OPERATION
Front impact severity sensor
E135483
There are two front impact severity sensors located
at the front of the vehicle, behind the radiator grille.
The sensors transmit digitally encoded acceleration
information to the RCM, where it is evaluated to
assess the severity of a front impact. Power is
supplied to the sensor by the RCM. If the sensor
fails, the RCM stores a diagnostic trouble code
(DTC).
Safety belt retractor and pretensioners
E135484
The front outboard seat belts are available
equipped with a retractor pretensioner and load
limiter. In the event of a collision, the safety belt
pretensioner deploy in one of two ways:
• On their own.
• Simultaneously with the front air bag module(s).
Safety belt use is necessary to obtain the best
occupant protection and to receive the full
advantage of the SRS.
Side air bag
E135485
The side air bags are incorporated in the front seat
backrests and side air bag modules deploy from
the outboard of front seat backrest upon a side
impact.
When a side air bag is deployed, the seam of the
seat cover tears open enabling the side air bag to
inflate unhindered from the front seat backrest.
Passenger air bag
E135487
The passenger air bag is designed to provide
increased collision protection for front seat
passengers.

Adhesive Tape
WARNINGS:
If there is a break between installing the
clockspring and steering wheel rotation
sensor assembly and installing the
steering wheel, the centralizing of the
clockspring must be repeated.
If the centralization of the clockspring is
in doubt, the centralizing of the clockspring
must be repeated.
NOTE: Make sure that the road wheels are in the
straight ahead position.
1.
1.
Turn the clockspring in a clockwise direction
until a resistance is felt.
2. Turn the clockspring in a counterclockwise
direction 2.5 revolutions, until the arrow
marked on the rotor of the clockspring aligns
with the raised 'V' section on the outer cover
of the clockspring.

GENERAL PROCEDURES
Deployed Air Bag Disposal
WARNING: After deployment, the air bag
module surface may contain deposits of
sodium hydroxide, a product of the gas
generate combustion, that is irritating to
the skin. Use protective gloves when
handling any deployed air bag module.
Failure to follow this instruction may result
in personal injury.
1. Remove the deployed air bag module(s). For
additional information, refer to the relevant
procedure in this section.
2. Seal the deployed air bag module(s) in the
packaging from the new air bag module(s)
or a suitable polythene bag, and then
dispose of in accordance with local
contaminated waste regulations.

WARNINGS:
To avoid accidental deployment, the
restraints control module (RCM) backup
power supply must be depleted. Wait at
least one minute after disconnecting the
battery ground cable(s) before
commencing any repair or adjustment to
the supplemental restraint system (SRS),
or any component(s) adjacent to the SRS
sensors. Failure to follow these
instructions may result in personal injury.
To minimize the possibility of premature
deployment, do not use radio key code
savers when working on the SRS. Failure
to follow this instruction may result in
personal injury.
Before deploying the air bag module or
safety belt pretensioner pyrotechnic make
sure that all personnel in the vicinity are
aware that a loud noise (bang) is about to
occur. Do not let anybody approach closer
than 6 meters. Failure to follow this
instruction may result in personal injury.
The air bag module or the safety belt
pretensioner should not be handled
immediately following deployment as the
air bag module will be very hot. Failure to
follow this instruction may result in
personal injury.
After deployment, the inflator(s) becomes
inert, direct contact to the skin or eyes of
any free pyrotechnic residues should be
avoided. Failure to follow this instruction
may result in personal injury.
Always wear gloves and safety glasses
when handling deployed air bag modules
and safety belt pretensioners, Failure to
follow this instruction may result in
personal injury.
If the air bag module or safety belt
pretensioner pyrotechnic residue should
contact the eyes, wash the eyes with clean
water and seek medical assistance. Failure
to follow this instruction may result in
personal injury.
If a large amount of air bag or safety belt
pretensioner pyrotechnic residue is
inhaled, seek medical assistance. Failure
to follow this instruction may result in
personal injury.
