CONSULT-II Reference Value in Data Monitor ModeINFOID:0000000001702930
Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001702931
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.
This self-diagnosis has the one trip detection logic.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-8, "
Changing Engine
Coolant". Also, replace the engine oil. Refer to LU-7, "Changing Engine Oil".
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-11, "
Anti-freeze Coolant Mixture Ratio".
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckINFOID:0000000001702932
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.

PRECAUTIONS
• Use hand tools, power tools (disassembly only) and recommended
special tools where specified for safe and efficient service repairs.
• When repairing the fuel, oil, water, vacuum or exhaust systems,
check all affected lines for leaks.
• Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precaution for Three Way CatalystINFOID:0000000001702425
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
• 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 nec-
essary.
• Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to the
catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precaution for Fuel (Unleaded Regular Gasoline Recommended)INFOID:0000000001702426
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel
(i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect
the emission control devices and systems, and could also affect the warranty coverage validity.

seems unusual or there is a smell of exhaust fumes, immediately locate the trouble
and correct it.MA-19
UnderbodyThe underbody is frequently exposed to corrosive substances such as those used
on icy roads or to control dust. It is very important to remove these substances, oth-
erwise rust will form on the floor pan, frame, fuel lines and around the exhaust sys-
tem. At the end of winter, the underbody should be thoroughly flushed with plain
water, being careful to clean those areas where mud and dirt can easily accumu-
late.—
Fluid leaksCheck under the vehicle for fuel, oil, water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the air conditioner after use is normal.
If you should notice any leaks or gasoline fumes are evident, check for the cause
and correct it immediately.—
