Torque Specifications
Torque sp
ecifications are shown in maintenance procedure illustra
tions and also in the torque specifications chart located at
the front of the relevant section.
Disconnecting/Connecting the Battery
Ow ing t
o the electronic components used on the vehicle, it is important that the battery is disconnected when specified in a
maintenance procedure.
When the battery is connected, the specified procedure must be followed, to ensure the correct operation of all vehicle
systems; refer to Section 414-01.
Use of Control Modules
Control modu les may
only be used on the ve
hicle to which they were originally fitted. Do not attempt to use or test a control
module on any other vehicle.
Function
al Test
On
completion of a maintenance procedure, a thorough test should be carried out, to ensu
re that the relevant vehicle
systems are working correctly.
Protecting the Vehicle
Al ways
fit covers to protect
the fenders before commencing work in the engi ne compartment. Cover the seats and carpets,
wear clean overalls and wash hands or wear gloves before working inside the vehicle. Avoid spilling hydraulic fluid,
antifreeze or battery acid on the paintwork. In the event of spillage, wash off with water imme diately. Use polythene sheets
in the trunk to protect carpets. Always use the recommended service tool, or a satisfactory equivalent, where specified.
Protect temporarily exposed screw thread s by replacing nuts or fitting caps.
Preparation
Before disassembly, clean the surrounding ar ea
as thoroughly as possible. When co
mponents have been removed, blank off
any exposed openings using grease-proof paper and masking tape. Immediately seal fuel, oil and hydraulic lines when
separated, using plastic caps or plugs, to prevent loss of fluid and the entry of dirt. Close the open ends of oilways, exposed
by component removal, with tapered hardw ood plugs or readily visible plastic plugs. Immediately a component is removed,
place it in a suitable container; use a se parate container for each component and its associated pa rts. Before dismantling a
component, clean it thoroughly with a recommended cleaning agent; check that the agent will not damage any of the
materials within the component. Clean the bench and obtain ma rking materials, labels, containers and locking wire before
dismantling a component.
Dismantling
O b
serve scrupulous cleanliness when dismantling components,
particularly when parts of the brake, fuel or hydraulic
systems are being worked on. A particle of dirt or a fragment of cloth could caus e a dangerous malfunction if trapped in
these systems. Clean all tapped holes, crev ices, oilways and fluid passages with compressed air. Do not permit compressed
air to enter an open wound. Always use ey e protection when using compressed air.
Ensure that any O-rings used for sealing are correctly refitted or renewed if disturbed. Mark mating parts to ensure that
they are replaced as dismantled. Whenever possible use markin g materials which avoid the possibilities of causing distortion
or the initiation of cracks, which could occur if a center pu nch or scriber were used. Wire together mating parts where
necessary to prevent accidental interchange (e.g roller bearing components). Tie labels on to all parts to be renewed and to
parts requiring further inspection before being passed fo r reassembly. Place labelled parts and other parts for rebuild in
separate containers. Do not disc ard a part which is due for renewal until it ha s been compared with the new part, to ensure
that the correct part has been obtained.
Before inspecting a component for wear or per
forming a dimensional check,
ensure that it is absolutely clean; a slight smear
of grease can conceal an incipient failure. When a component is to be checked dimensionally against figures quoted for it,
use the correct equipment (surface plates, micrometers, dial gauges etc.) in serviceable condition. The use of makeshift
equipment can be dangerous. Reject a component if its dimensio ns are outside the limits quoted, or if damage is apparent.
A part may be refitted if its critical di mension is exactly to the limit size and it is otherwise satisfactory. Use Plastigauge 12
Type PG-1 for checking bearing surface clearance, e.g. big end bearing shell to crank jour nal. Instructions for the use of
Plastigauge and a scale giving bearing clearances in steps of 0.0025 mm (0.0001 in) are supplied with the package.

Wh
en using electrical tools and equipment, inspect the power
lead for damage and check that it is properly earthed.
D
o not leave tools, equipment, spilt oil etc. around the work area.
Working beneath a vehicle:
Wh
enever possible, use a ramp or

It is a reciprocating two
-circuit pu
mp in which one brake circuit is as signed to each pump circuit.
It supplies th
e fluid pressure and vo
lume to supply the brake circuits under ABS and Traction control.
The pump is driven by an electri
c motor, with the pump
housing incorporating two lo w pressure accumulators and
damping chambers for each brake circuit.
The ac cu
mulator stores the pressure and smooths out the output pu
lses from the pump.
ABS Warning Lamp
The sys
tem will be set in a fail-safe mode if a problem is de
tected; a warning lamp on the instrument panel will notify the
driver there is a problem.
Anti-Lock Braking Sy
stem (ABS)
The AB
S components are combined with
an hydraulic booster and a tandem master cylinder to provide a two circuit braking
system. The system comprises, four wheel speed sensor s, a brake control modulator and an ABS warning lamp.
Should a wheel start to lock-up during braking a signal tr ansmitted from the wheel speed sensor to the brake control
modulator will start the hydraulic pump. The brake control modula tor will close the input valve of the line connected to the
locked-wheel to stop any increase in fluid pressure to the br ake caliper. If this fails to prevent the wheel locking, the
pressure in the caliper will be decreased by opening the return valve until th e wheel starts accelerating again. The fluid
pressure from the return va lve is directed into the low pressure accumulator, housed in the pump.
From the low pressure accumulator, fl uid is pumped through the damping cham ber to the brake master cylinder. The
pressure to the brake caliper will then be increased in small steps to maintain maximum adhesion between the tire and road
surface. This is achieved by closing the return valve, and opening the input valve and using the hydraulic pump to increase
the pressure.
Although the system senses all four wheels independently, the rear wheels are regulated as a pair. If a sensor on a rear
wheel detects a wheel decelerating rapidly, then the fluid pressure to both wheels is reduced. The fluid pressure is then
dictated by the wheel having the lowe st adhesion with the road surface.
The ABS system will be set in a fail-safe mode if a problem is detected; a warn ing lamp on the instrument panel will notify
the driver there is a problem. The brake system will still operate conventionally and with the same standard of performance
as a vehicle not equipped with ABS.
Automa tic Stability Control (ASC)
Th
e ASC utilizes the ABS sensing arrangement to provide the maximum traction force to propel the vehicle.
The ASC is switched on when the engine is started. The system can be switched off by pressing the 'ASC OFF' (the switched
is marked 'TRAC OFF' on vehicles fitted with traction control). The switch, which is situated in the center console switchpack,
lights up to warn that the system is sw itched off. An 'ASC' amber warning light flashes on the instrument panel when the
system detects a spinning wheel.
The ASC system uses engine intervention to reduce the torque delivered to the drive wheels to prevent them spinning.
Engine torque is re duced in three ways:
The
throttle is moved towards the closed position.
The ignition is retarded. F
u
el is cut-off at the cylinder injectors.
Wheel spin is detected by the wheel sp eed sensors and communicated to the AB S/TCCM. The ABS/TCCM uses information
from the controller area network (CAN) to calculate the torque that the engine should produce to stop the wheel spinning.
Torque reductions are then requested from the engine control module (ECM ) through the CAN. The throttle is then
positioned to provide the target torque, which has been calculated to prevent wheel spin. During the transient phase of
torque reduction the fuel is cut-off and th e ignition retarded Both the fuel cut-off an d ignition retard will be restored to
normal when the throttle is set to its new position.
The ASC uses a brake control modulator with six solenoid va lves: three normally open inlet valves and three normally
