GENERAL INFORMATION
03-21
It should be noted that these precautions are not
restricted to operations performed when servicing
the SRS system, the same care should be exercised
when working on ancillary systems and components
located in the vicinity of SRS components; these
include but are not limited to:
lSteering system – steering wheel airbag,
rotary coupler.
lFront fascia – passenger front airbag (where
fitted); SRS DCU behind centre console, on
transmission tunnel under the HeVAC system.
lFront seats – seat belt pre-tensioners, integral
with seat belt buckle assembly.
lElectrical system – SRS harnesses, link leads
and connectors.
Making the SRS system safe
Before working on or in the vicinity of SRS
components, ensure the system is rendered safe by
performing the following procedures:
lRemove the ignition key from the ignition switch.
lDisconnect both battery leads, earth lead first.
lWait 10 minutes for the SRS DCU back-up
power circuit to discharge.
The SRS system uses energy reserve capacitors
that keep the system active in the event of electrical
supply failure under crash conditions. It is necessary
to allow the capacitor sufficient time to discharge (10
minutes) in order to avoid the risk of accidental
deployment.
WARNING: Always disconnect both battery leads
before beginning work on the SRS system.
Disconnect the negative battery lead first. Never
reverse connect the battery.Installation
In order to assure system integrity, it is essential that
the SRS system is regularly checked and maintained
so that it is ready for effective operation in the event
of a collision. Carefully inspect SRS components
before installation. Do not install a part that shows
signs of being dropped or improperly handled, such
as dents, cracks or deformation.
WARNING: The integrity of SRS system
components is critical for safety reasons. Ensure
the following precautions are always adhered to:
lNever install used SRS components from
another vehicle or attempt to repair an SRS
component.
lWhen repairing an SRS system only use
genuine new parts.
lNever apply electrical power to an SRS
component unless instructed to do so as
part of an approved test procedure.
lSpecial Torx bolts are necessary for
installing the airbag module — do not use
other bolts. Ensure bolts are tightened to the
correct torque.
lAlways use new fixings when replacing an
SRS component.
lEnsure the SRS Diagnostic Control Unit
(DCU) is always installed correctly. There
must not be any gap between the DCU and
the bracket to which it is mounted. An
incorrectly mounted DCU could cause the
system to malfunction.
CAUTION: Ensure SRS components are not
contaminated with oil, grease, detergent or
water.
Ensure that SRS component fixings are correctly
positioned and torqued during service and repair.
CAUTION: Torque wrenches should be regularly
checked for accuracy to ensure that all fixings
are tightened to the correct torque.
If you suspect an airbag assembly could be
defective, install a new unit and dispose of the old
unit. Manually deploy the old unit before disposal.
MAINTENANCE
10-28 MAINTENANCE
Steering
Check
1.Check/tighten steering unit and steering rod
ball joint fixings.
2.Check condition of ball joints and dust covers.
3.Check steering rack bellows for any signs of
leakage.
Road Test
There are two purposes for conducting a road test.
Firstly, to ensure the work completed within the
dealership meets the standards required as laid
down by dealership processes. Secondly, for a
skilled technician to assess the general condition of
the vehicle and report any conditions that the
customer should be made aware of.
CAUTION: Two wheel dynamometer tests must
not be carried out. Four wheel dynamometer
tests must be restricted to 3 mph (5 kph).
Engine Start
1.Check for correct operation of starter switch.
Ensure the engine starts in a correct manner.
Leave the engine running.
Starter Inhibitor Switch – (Automatic only)
1.Select 'D' gear lever position.
2.Check that engine will not start.
3.Select 'R' gear lever position and repeat start
check.
4.Check that engine will start in 'P' and 'N'
positions.
Selector Cable – (Automatic only)
1.Check for correct setting of gear selector cable.
Engine Performance and Throttle Operation
1.Start engine and check that it starts easily.
2.Check that 'oil pressure' and 'no charge'
warning lamps extinguish.
3.Check that throttle pedal movement is free and
unrestricted.
4.Check that engine is responsive to throttle
movement.
Clutch and Gear Selection –
(Manual only, normal driving conditions)
1.Check that clutch engages smoothly without
judder, slipping or noise.
2.Check for abnormal transmission noise.
3.Check for smooth quiet gear changes and that
gear selected engages easily.
PANEL REPAIRS
BODY REPAIRS 77-2-1
PANEL REPAIRS
General
Body shells are of monocoque construction. Front and rear sections of the shell are designed as 'energy absorbing'
zones. This means they are designed to deform progressively when subjected to impact in order to minimise the
likelihood of injury to vehicle occupants.
It is essential that design dimensions and strength are restored in accident rectification. It is important that neither
structural weakness nor excessive local stiffness are introduced into the vehicle during body repair.
Repairs usually involve a combination of operations ranging from straightening procedures to renewal of individual
panels or panel assemblies. The repairer will determine the repair method and this decision will take into account a
balance of economics between labour and material costs and the availability of repair facilities in both equipment and
skills. It may also involve considerations of the vehicles' downtime, replacement vehicle availability and repair turn-
around time.
It is expected that a repairer will select the best and most economic repair method possible, making use of the facilities
available. The instructions given are intended to assist a skilled body repairer by expanding approved procedures for
panel replacement. The objective is to restore the vehicle to a safe running condition by carrying out a repair which is
as close as is feasible to original standard. The results should not advertise to the experienced eye that the vehicle
has been damaged, although the repair might not be identical in all respects to the original factory build. Commercial
bodyshop repair facilities cannot always duplicate methods of construction used during production.
Operations covered in this Manual do not include reference to testing the vehicle after repair. It is essential that work
is inspected and suspension geometry checked after completion. Where necessary a road test of the vehicle should
be carried out, particularly where safety-related items are concerned.
Where major units have been disconnected or removed it is necessary to ensure that fluid levels are checked and
topped up where necessary. It is also necessary to ensure that the repaired vehicle is in a roadworthy condition in
respect of tyre pressures, lights, washer fluid etc.
Body repairs often involve the removal of mechanical and electrical units and associated wiring. Where necessary,
refer to the relevant section of the Workshop Manual for removal and refitting instructions.
Body components
Taking into consideration the differences in body styles, suspension systems and engine and transmission layouts,
the location of the following components as applicable to a particular vehicle is critical:
lFront suspension upper damper mountings.
lFront suspension or sub frame mountings.
lRear suspension upper damper mountings.
lRear suspension mountings or lower pivots.
Additional points which can be used to check alignment and assembly are:
lInner holes in crossmember - side - main floor.
lHoles in front longitudinals.
lHoles in side members.
lHoles in rear longitudinals.
lHoles in rear lower panels or extension rear floor.
Apertures for windscreen, backlight, bonnet and doors can be measured and checked using the dimensional
information provided and also by offering up an undamaged component as a gauge.
Straightening
Whenever possible, structural members should be cold straightened under tension. Do not attempt to straighten with
a single pull but rework the damaged area using a series of pulls, releasing tension between each stage and using
the opportunity to check alignment.
