PRE-INSPECTION CONDITION

M1001012100388

"Pre-inspection condition" refers to the condition that
the vehicle must be in before proper engine inspec-
tion can be carried out. If you see the words "Set the
vehicle to the pre-inspection condition" in this man-
ual. It means to set the vehicle to the following condi-
tion.

• Engine coolant temperature 80 to 90°C

• Lamps, electric cooling fan and all accessories:

OFF

• M/T: Neutral

• A/T: P range

ENGINE OILS

M1001011200155

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 addi-
tion, used engine oil contains potentially harmful con-
taminants 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.

PRECAUTIONS BEFORE SERVICE

GENERAL

00-43

• Wear protective clothing, including impervious

gloves where practicable.

• Avoid contaminating clothes, particularly under-

pants, 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 separately from personal cloth-
ing.

• Where there is a risk of eye contact, eye protec-

tion should be worn, for example, chemical gog-
gles 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 clean-
ing, 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.

WHAT THE COMMON RAIL ENGINE LEARNS

M1001012500018

After fuel-related parts are replaced, the common rail
engine must register their identification codes with
the engine-ECU and execute learning.
The table below shows what should be registered
and learned after each type of operation.

NOTE: When the engine-ECU is replaced, collect in
advance the injector identification code from the cur-
rent engine-ECU. Doing it makes registration easy.

INJECTOR IDENTIFICATION CODE REGISTRATION PROCEDURE

M1001012600015

CAUTION

1. If the injector identification code is not regis-

tered, the engine warning lamp goes on and
diagnosis code No. P1626 is logged.

2. Failure to register the injector identification

code correctly will cause rough idling, abnor-
mal noise, and emission deterioration.

PURPOSE

AK501491

Identification code

AB

Because individual injectors have different injection
characteristics, the engine-ECU corrects injection
time for each cylinder to improve injection accuracy.
