Component Description
Malfunction Indicator (MI) is located on the instrument panel. When the ignition switch is turned ON without
engine running, MI will light up. This is a bulb check. When the engine is started, MI should go off. If MI remains
on, the on board diagnostic system has detected an engine system malfunction.

SYSTEM DESCRIPTION
SensorInput signal to ECM ECM functionActuator
Engine coolant temperature
sensor Engine coolant temperature
Cooling fan control Cooling fan relay
Air conditioner switch Air conditioner ªONº signal
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, air condi-
tioner ON signal.
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.

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.
