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.

For more information, refer to ªMAIN 12 CAUSES OF
OVERHEATINGº, EC-448.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the LC
section, ªChanging Engine Coolantº. Also, replace the 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 section, ªEngine Coolant Mixture Ratioº.
2) After refilling coolant, run engine to ensure that no water-flow noise is emitted.

Overall Function Check
Use this procedure to check the overall function of the cooling fan.
During this check, a DTC might not be confirmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap
by turning it a quarter turn to allow built-up pressure to
escape. Then turn the cap all the way off.
WITH CONSULT-II
1) Check the coolant level in the reservoir tank and radiator.Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-444.
2) Confirm whether customer filled the coolant or not. If customer filled the coolant, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-444.
3) Turn ignition switch ªONº.
4) Perform ªCOOLING FANº in ªACTIVE TESTº mode with CON- SULT-II and make sure that cooling fans operate.
If NG, go to ªDiagnostic Procedureº, EC-444.
WITHOUT CONSULT-II
1) Check the coolant level in the reservoir tank and radiator.Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-444.
2) Confirm whether customer filled the coolant or not. If customer filled the coolant, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-444.
3) Start engine. Be careful not to overheat engine.
4) Set temperature control lever to full cold position.
5) Turn air conditioner switch ªONº.
6) Turn blower fan switch ªONº.
7) Run engine at idle for a few minutes with air conditioner oper- ating.
Be careful not to overheat engine.
8) Make sure that cooling fans operate at low speed.
9) Turn ignition switch ªOFFº.
10) Turn air conditioner switch and blower fan switch ªOFFº.
11) Disconnect engine coolant temperature sensor harness con- nector.
12) Connect 150W resistor to engine coolant temperature sensor
harness connector.
13) Start engine and make sure that cooling fans operate at higher speed than low speed.
Be careful not to overheat engine.
14) If NG, go to ªDiagnostic Procedureº, EC-444.

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replacable
halogen bulb. The bulb can be replaced from the engine compart-
ment side without removing the headlamp body.
IGrasp only the plastic base when handling the bulb. Never
touch the glass envelope.
1. Disconnect the battery cable.
2. Disconnect the harness connector from the back side of the bulb.
3. Pull off the rubber cap.
4. Press end of the retaining pin together to release bulb.
5. Remove the headlamp bulb. Do not shake or rotate the bulb when removing it.
6. Install the new bulb in reverse order of removal.
CAUTION:
I Do not leave headlamp reflector without bulb for a long
period of time as dust, moisture, smoke, etc. may enter the
headlamp body and affect the performance of the head-
lamp. Thus, the headlamp bulb should not be removed
from the headlamp reflector until just before a replacement
bulb is to be installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. For operating
instructions, of any aimer, it should be in good repair, calibrated and
used according to respective operation manuals supplied with the
unit.
For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following:
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is noload in vehicle other than coolant,
engine oil filled up to correct level, full fuel tank and the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ª0º when performing aiming
adjustment on vehicles equipped with headlamp aiming con-
trol.

Front Fog Lamp Aiming Adjustment
When performing fog lamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. The aimer should
be in good operational condition, calibrated and used according to
the relevant operation manuals supplied with the unit.
If an aimer is not available, aiming adjustment can be done as fol-
lows:
For details, refer to the regulations in your own country.
CAUTION:
IKeep all tires inflated to correct pressures.
I Place vehicle and tester on one and the same flat surface.
I Ensure that there is no-load in the vehicle other than
coolant, engine oil (filled up to correct level), full fuel tank
and the driver (or equivalent weight placed in driver's posi-
tion).
For details of front fog lamp aiming adjustment, refer to ªAiming
Adjustmentº, EL-47.
Check the distance between the vehicle and the ground illumina-
tion point of the main axis of the fog lamp beam. Keep the distance
to approximately 40 m (131 ft).
