IN ORDER TO PREVENT VEHICLES FROM FIRE
“Improper installation of electrical or fuel related parts could cause a fire. In order to retain the high
quality and safety of the vehicle, it is important that any accessories that may be fitted or modifications/repairs
that may be carried out which involve the electrical or fuel systems, MUST be carried out in accordance
with MMC’s information/Instructions”.
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:
DAvoid prolonged and repeated contact with oils, particularly used engine oils.
DWear protective clothing, including impervious gloves where practicable.
DAvoid contaminating clothes, particularly underpants, with oil.
DDo not put oily rags in pockets, the use of overalls without pockets will avoid this.
DDo not wear heavily soiled clothing and oil-impregnated foot-wear. Overalls must be cleaned regularly
and kept separately from personal clothing.
DWhere 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.
DObtain First Aid treatment immediately for open cuts and wounds.
DWash 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.
DDo not use petrol, kerosine, diesel fuel, gas oil, thinners or solvents for cleaning skin.
DUse barrier creams, applying them before each work period, to help the removal of oil from the skin
after work.
DIf skin disorders develop, obtain medical advice without delay.

(4) Hold the special tool (MB991668) to the middle of
the belt between the pulleys (at the place indicated
by the arrow) about 10 - 20 mm away from the rear
surface and so that it is perpendicular to the belt
(within an angle of±15°).
(5) Gently tap the middle of the belt between the pulleys
(at the place indicated by the arrow) with your finger
as shown in the illustration, and check that the
vibration frequency of the belt is within the standard
value.
Standard value: 110 - 144 Hz
Caution
1) Check the vibration frequency of the belt when
the temperature of the surface of the belt is
as close as possible to normal temperature.
2) Do not let any contaminants such as water
or oil get onto the microphone.
3) If strong gusts of wind blow against the
microphone or if there are any loud sources
of noise nearby, the values measured by the
microphone may not correspond to actual
values.
4) If the microphone is touching the belt while
the measurement is being made, the values
measured by the microphone may not
correspond to actual values.
5) Do not take the measurement while the
vehicle’s engine is running.

Use the belt tension gauge and check that the belt tension
of the middle of the belt between pulleys
(at the place indicated by arrow) is within the standard
value.

Standard value: 5_BTDC±3_
5. Run the engine at idle for 2 minutes.
6. Check the idle speed. Select item No. 22 and take a
reading of the idle speed.
Curb idle speed: 850±100 r/min
NOTE
The idle speed is controlled automatically by the idle speed
control (ISC) system.
7. If the idle speed is outside the standard value, check
the MPI components by referring to GROUP 13A -
Troubleshooting.
8. Remove the timing light.
9. Turn the ignition switch to the “LOCK” (OFF) position
and then remove the MUT-II.
IDLE MIXTURE CHECK
1. Before inspection, set the vehicle to the pre-inspection
condition.
2. Turn the ignition switch to the “LOCK” (OFF) position,
and then connect the MUT-IIto the diagnosis connector.
3. Set the timing light.
4. Check that the basic ignition timing is within the standard
value.
Standard value: 5_BTDC±3_
5. Run the engine at 2,500 r/min for 2 minutes.
6. Set the CO, HC tester.
7. Check the CO contents and the HC contents at idle.
Standard value
CO contents: 0.1% or less
HC contents: 100 ppm or less
8. If there is a deviation from the standard value, check the
following items:
DDiagnosis output
DClosed-loop control (When the closed-loop control
is normal, the output signal of the oxygen sensor
changes between 0 - 400 mV and 600 - 1,000 mV
at idle.)
DFuel pressure
DInjector
DIgnition coil, spark plug cable, spark plug
DEvaporative emission control system
DCompression pressure
NOTE

10. Turn the ignition switch to the “LOCK” (OFF) position
and then remove the MUT-II.
COMPRESSION PRESSURE CHECK
1. Before inspection, check that the engine oil, starter and
battery are normal. In addition, set the vehicle to the
pre-inspection condition.
2. Remove the ignition coils and spark plug cables.
3. Remove all of the spark plugs.
4. Disconnect the crank angle sensor connector.
NOTE
Doing this will prevent the engine-ECU from carrying out
ignition and fuel injection.
5. Cover the spark plug hole with a shop towel etc., and
after the engine has been cranked, check that no foreign
material is adhering to the shop towel.
Caution
(1) Keep away from the spark plug hole when
cranking.
(2) If compression is measured with water, oil, fuel,
etc., that has come from cracks inside the cylinder,
these materials will become heated and will gush
out from the spark plug hole, which is dangerous.
6. Set compression gauge to one of the spark plug holes.
7. Crank the engine with the throttle valve fully open and
measure the compression pressure.
Standard value (at engine speed of 250 r/min):
1,128 kPa
Limit (at engine speed of 250 r/min):
Min. 951 kPa
8. Measure the compression pressure for all the cylinders,
and check that the pressure differences of the cylinders are
below the limit.
Limit: Max. 98 kPa
9. If there is a cylinder with compression or a compression
difference that is outside the limit, pour a small amount
of engine oil through the spark plug hole, and repeat
the operations in steps 7 and 8.
(1) If the compression increases after oil is added, the
cause of the malfunction is a worn or damaged piston
ring and/or cylinder inner surface.
(2) If the compression does not rise after oil is added,
the cause is a burnt or defective valve seat, or pressure
is leaking from the gasket.
10. Connect the crank angle sensor connector.
11. Install the spark plugs.
