ON BOARD DIAGNOSIS LOGIC
This diagnosis continuously monitors the engine coolant temperature.
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
Diagnostic Trouble
Code No.Malfunction is detected when ...Check Items
(Possible Cause)
28+Cooling fan does not operate properly (Overheat).
+Cooling fan system does not operate properly (Over-
heat).
+Engine coolant was not added to the system using
the proper ®lling method.+Harness or connectors
(The cooling fan circuit is open or shorted.)

For more information, refer to ``MAIN 12
CAUSES OF OVERHEATING'', EC-120.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the MA
section (``Changing Engine Coolant'', ``ENGINE MAINTENANCE''). Also, replace the engine oil.
a. Fill radiator with coolant up to speci®ed level with a ®lling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA section (``Anti-freeze Coolant Mixture Ratio'',
``RECOMMENDED FLUIDS AND LUBRICANTS'').
b. After re®lling coolant, run engine to ensure that no water-¯ow noise is emitted.

CHECK COOLING SYSTEM FOR LEAK.
Apply pressure to the cooling system with
a tester, and check if the pressure drops.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
Pressure should not drop.
CAUTION:
Higher than the speci®ed pressure may
cause radiator damage.
OK

Check the following for
leak.

+Radiator
+Water pump
Refer to LC section (``Water
Pump'').
CHECK RADIATOR CAP.
Apply pressure to cap with a tester.
Radiator cap relief pressure:
78 - 98 kPa (0.78 - 0.98 bar, 0.8 - 1.0

2, 11 - 14 psi)
OK
cNG
Replace radiator cap.
CHECK THERMOSTAT.
1. Check valve seating condition at normal
room temperatures.
It should seat tightly.
2. Check valve opening temperature and
valve lift.
Valve opening temperature:
82ÉC (180ÉF) [standard]
Maximum valve lift:
More than 10 mm/95ÉC
(0.39 in/203ÉF)
3. Check if valve is closed at 5ÉC (9ÉF)
below valve opening temperature.
For details, refer to LC section (``Thermo-
stat'').
OK
cNG
Replace thermostat.
Check engine coolant temperature sensor.
Refer to ``COMPONENT INSPECTION'',
EC-82.
OK

Replace engine coolant
temperature sensor.
If the cause cannot be isolated, go to
``MAIN 12 CAUSES OF OVERHEATING''
on next page.
INSPECTION END
Perform FINAL CHECK by the following procedure after repair
is completed.
1. Warm up engine. Run the vehicle for at least 20 minutes. Pay
attention to engine coolant temperature gauge on the instrument
panel. If the reading shows an abnormally high temperature,
another part may be malfunctioning.
2. Stop vehicle and let engine idle. Check the intake and exhaust
systems for leaks by listening for noise or visually inspecting the
components.
3. Allow engine to cool and visually check for oil and coolant leaks.
Then, perform ``OVERALL FUNCTION CHECK''.

COMPONENT INSPECTION
Glow relay
1. Check relay for coil continuity.
Continuity should exist.
2. Check relay for proper operation.
Coil voltage Continuity Contact point

12V Yes ON
Glow plug
1. Remove glow plug connecting plate.
2. Check each glow plug for continuity.
Continuity should exist:
Approximately 0.8W[at 25ÉC (77ÉF)]
+If NG, replace glow plug.
3. Install glow plug connecting plate securely.
+Do not bump glow plug heating element. If it is bumped,
replace glow plug with new one. (If glow plug is dropped
from a height of 10 cm (3.94 in), replace with new one.)
+If glow plug installation hole is contaminated with carbon,
remove using a reamer or suitable tool.
+Hand-tighten glow plug by turning it two to three times,
then tighten using a tool to speci®ed torque.

Precautions for Three Way Catalyst
(If so equipped)
If a large amount of unburned fuel ¯ows into the catalyst, the cata-
lyst temperature will be excessively high. To prevent this, follow the
instructions below:
+Use unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
+When checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
+Do not run engine when the fuel tank level is low, otherwise the
engine may mis®re causing damage to the catalyst.
Do not place the vehicle on ¯ammable material. Keep ¯ammable
material off the exhaust pipe and the three way catalyst.
Precautions for Engine Oils
Prolonged and repeated contact with used engine oil may cause
skin cancer. Try to avoid direct skin contact with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner
as soon as possible.
HEALTH PROTECTION PRECAUTIONS
+Avoid prolonged and repeated contact with oils, particularly
used engine oils.
+Wear protective clothing, including impervious gloves where
practicable.
+Do not put oily rags in pockets.
+Avoid contaminating clothes, particularly underpants, with oil.
+Heavily soiled clothing and oil-impregnated footwear should not
be worn. Overalls must be cleaned regularly.
+First Aid treatment should be obtained immediately for open
cuts and wounds.
+Use barrier creams, applying them before each work period, to
help the removal of oil from the skin.
+Wash with soap and water to ensure all oil is removed (skin
cleansers and nail brushes will help). Preparations containing
lanolin replace the natural skin oils which have been removed.
+Do not use gasoline, kerosine, diesel fuel, gas oil, thinners or
solvents for cleaning skin.
+If skin disorders develop, obtain medical advice without delay.
+Where practicable, degrease components prior to handling.
+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.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Burning used engine oil in small space heaters or boilers can be
recommended only for units of approved design. The heating sys-
tem must meet the requirements of HM Inspectorate of Pollution for
small burners of less than 0.4 MW. If in doubt check with the
appropriate local authority and/or manufacturer of the approved
appliance.
PRECAUTIONS
GI-4
Page 778 of 1226
Dispose of used oil and used oil ®lters 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.
It is illegal to pour used oil on to the ground, down sewers or drains,
or into water courses.
The regulations concerning the pollution of the environment
will vary from country to country.
Precautions for Fuel
GASOLINE ENGINE:
Three way catalyst equipped models ... unleaded gasoline of at
least 91 octane (RON)
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will dam-
age the three way catalyst.
Except for the above models ... unleaded or leaded gasoline of
above 88 octane (RON)
Use unleaded fuel if instructed on the fuel ®ller lid.
DIESEL ENGINE*:
Diesel fuel of above 45 cetane for TD42 engine and above 50 cet-
ane for RD28ET engine
* If two types of diesel fuel are available, use summer or winter
fuel properly according to the following temperature conditions.
+Above þ7ÉC (20ÉF) ... Summer type diesel fuel.
+Below þ7ÉC (20ÉF) ... Winter type diesel fuel.
CAUTION:
+Do not use home heating oil, gasoline, or other alternate
fuels in your diesel engine. The use of those can cause
engine damage.
+Do not use summer fuel at temperature below þ7ÉC (20ÉF).
The cold temperature will cause wax to form in the fuel. As
a result, it may prevent the engine from running smoothly.
+Do not add gasoline or other alternate fuels to diesel fuel.
Precautions for Air Conditioning
Use an approved refrigerant recovery unit any time the air condi-
tioning system must be discharged. Refer to HA section (``HFC-
134a (R-134a) Service Procedure'', ``SERVICE PROCEDURES'')
for speci®c instructions.
