GENERAL INFORMATION
ENGINE LUBRICATION12-2
GENERAL INFORMATION
M1121000100357
The lubrication method is a fully force-fed, full-flow
filtration type. The engine oil pump is a trochoid type
which is driven by the crankshaft <4G1>.The engine
oil pump is a gear type which is driven by the
crankshaft via the balancer timing belt <4G6>.
ENGINE OILS
Health Warning
Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In
addition, used engine oil contains potentially harmful
contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities must be provided.
Recommended Precautions
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example by
using enclosed systems for handling used engine oil
and by degreasing components, where practicable,
before handling them. Other precautions:
•Avoid prolonged and repeated contact with oils,
particularly used engine oils.
•Wear protective clothing, including impervious
gloves where practicable.•Avoid contaminating clothes, particularly
underpants, with oil.
•Do not put oily rags in pockets, the use of overalls
without pockets will avoid this.
•Do not wear heavily soiled clothing and
oil-impregnated foot-wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.
•Where there is a risk of eye contact, eye
protection should be worn, for example, chemical
goggles or face shields; in addition an eye wash
facility should be provided.
•Obtain first aid treatment immediately for open
cuts and wounds.
•Wash regularly with soap and water to ensure all
oil is removed, especially before meals (skin
cleansers and nail brushes will help). After
cleaning, the application of preparations
containing lanolin to replace the natural skin oils
is advised.
•Do not use petrol, kerosine, diesel fuel, gas oil,
thinners or solvents for cleaning skin.
•Use barrier creams, applying them before each
work period, to help the removal of oil from the
skin after work.
•If skin disorders develop, obtain medical advice
without delay.

TROUBLESHOOTING
ENGINE COOLING14-7
CIRCUIT OPERATION
•The cooling fan motor drive control unit is
powered from fusible link (2).
•The engine-ECU or engine-A/T-ECU
uses input signals from the A/C switch, the
water temperature sensor unit and the vehicle
speed sensor or the output shaft speed
sensor to control the speed of the cooling
fan motor (L.H.) and the cooling fan motor (R.H.)
<4G1 (Vehicles with A/C)> or A/C condenser fan
motor <4G6>.
•The engine-ECU or engine-A/T-ECU
controls the cooling fan motor drive control
unit to activate the cooling fan motor (L.H.) and
the cooling fan motor (R.H.) <4G1 (Vehicles with
A/C)> or A/C condenser fan motor <4G6>.
TECHNICAL DESCRIPTION
•The cause could be a malfunction of the cooling
fan motor drive control unit power supply or earth
circuit.
•If the communication line wiring harness between
the cooling fan motor drive control unit and the
engine-ECU or engine-A/T-ECU is
short-circuited to earth, the cooling fan motor
(L.H.) and the cooling fan motor (R.H.) <4G1
(Vehicles with A/C)> or the A/C condenser fan
motor <4G6> will not rotate.
•The cause could also be a malfunction of the
cooling fan motor (L.H.).
•The cause could also be a malfunction of imput
signal from the A/C switch, the water temperature
sensor unit and the vehicle speed sensor
or the output shaft speed sensor to the
engine-ECU or engine-A/T-ECU .
•The cause could also be a malfunction of the
cooling fan motor drive control unit or the
engine-ECU or engine-A/T-ECU .
