tation and dermatitis. In addition, used engine oil contains potentially harmful contaminants which may cause skin
cancer. Washing facilities and adequate means of skin protection should be provided.
Observe these recommendations:
Wear pro t
ective clothing and impe
rvious gloves when necessary.
Do not put oily
rags in pockets. Avoid contaminat
ing clothes, particularly underwear, with oil.
Overal
ls must be cleaned re
gularly; discard oil impregna ted clothing and footwear wh ich cannot be washed or
cleaned.
Fi rst
Aid treatment should be obtained
immediately for open cuts or wounds.
Use barrier
creams, applying before each work period, to en
able easier removal of dirty oil and grease from the skin.
Wa
sh with soap and water to ensure th
at all oil is removed (skin cleaner and a nail brush will help). The use of
preparations containing lanolin will help to replace the natural skin oils which have been removed.
Do
not use petrol, kerosene, gas oil, th
inners or solvents for washing skin.
If
skin disorders develop, obtain medical advice immediately.
Wh
ere prac
ticable, degrease components prior to handling.
W
h
ere there is a risk of fluids coming into contact with th
e eyes, suitable eye protection should be worn - goggles or
face shield. An eye wash facility should be provided.
Ensure that a
dequate ventilation is provided when volatile degreasing agents are being used.
E
n
vironmental Protection
In so
m
e countries it is illegal to pour used oil onto the ground
, down sewers or drains, or into water courses. The burning of
used engine oil in small space heaters or boilers is not reco mmended unless emission control equipment is fitted. Dispose of
used oil through authorized waste disposal contractors, to licensed waste disposal sites or to the waste oil reclamation
trade. If in doubt, contact the Local Authority for advice on disposal facilities.
On-Board Diagnostics (OBD)
Ve
hicles use programmed electronic control systems to prov
ide engine management and emission regulation, automatic
transmission operation and anti -lock braking control. These control systems ha ve an integral On-Board Diagnostics (OBD)
facility for use in conjunction with either Jaguar diagnostic equipment or a scan t ool which is capable of retrieving DTCs,
PIDs and performing active commands.
The OBD information in this manual provid es diagnostic and rectification procedures for emission related electrical and
mechanical systems. The informat ion is intended to facilitate fault diagnosis and the subsequent rectification of vehicles
without recourse to the portab le diagnostic unit (PDU).
OBD related information can be fo und in the following sections:
General Information

Engine M

anagement System
Auto

matic Transmission
Anti-lock Br

Where appropriate a section comprises the following sub-sections:
Description and Operation
A ge
neral illustration and parts list to help the identi
fication of the particular system or component.
A b
rief description of the system operating characteristics and monitoring procedure
accompanied by a component
illustration.
Addi ti
onal information, where appropriat
e, is provided in the form of component calibrations, characteristics and
cross sectional views.
A localized circui
t diagram is included to provide circuit iden
tification and details of connectors, splices, fuses, wire
gauge and colors. See Circuit Diagrams.
Diagnosis and Testing (dedicated to fault analysis and rectification)
Recommended special tools. Symptom chart; a ch

CAUTION: If a steering gear assemb ly is returned under warranty with leaking seals, but there is also
damage to the steering gear boot/boots the steering gear warranty will be invalid. This is due to the steering
gear seals being damaged due to fore ign materials entering the steering gear boot and damaging the steering
gear seals thereafter.

ous cause for an observed or
reported concern is found, correct th e cause (if possible) before proceeding
to the next step.
4. 4. If the concern is not visually evident, refer to the Diagnostic trouble code (DTC) index.
CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit,
part number 3548-1358-00. Failure to follow this in struction may result in damage to the vehicle.
• NOTE: When performing electrical voltag e or resistance tests, always use a digital multimeter (DMM) accurate to 3
decimal places, and with an up-t o-date calibration certificate. When testing resistance, always take the resistance of the
DMM leads into account.
• NOTE: Check and rectify basic faults before beginning diagnostic ro utines involving pinpoint tests.
