On Board Diagnosis LogicNJEC0663This 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-756.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the LC-44,
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-18, ªEngine Coolant Mixture Ratioº.
2) After refilling coolant, run engine to ensure that no water-flow noise is emitted.

Overall Function CheckNJEC0664Use 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-IINJEC0664S011) 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-735.
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-735.
3) Turn ignition switch ªONº.
4) Perform ªCOOLING FANº in ªACTIVE TESTº mode with CON-
SULT-II and make sure that cooling fans operate when touch-
ing ªHIGHº or ªLOWº.
If NG, go to ªDiagnostic Procedureº, EC-735.
WITHOUT CONSULT-IINJEC0664S021) 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-735.
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-735.
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 150Wresistor to engine coolant temperature sensor
harness connector.

Aiming AdjustmentNJEL0016For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
1) Keep all tires inflated to correct pressures.
2) Place vehicle on flat surface.
3) See that there is no-load in vehicle (coolant, engine oil filled up
to correct level and full fuel tank) other than the driver (or
equivalent weight placed in driver's position).

The tachometer is regulated by a signal
+from terminal 32 (Gasoline engine models) or 439 (Diesel engine models) of the ECM
+to combination meter terminal 21 for the tachometer.
FUEL GAUGENJEL0042S03The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
+from body grounds B9, B21 and B308
+through terminal 1 (Gasoline engine models) or 3 (Diesel engine models) of the fuel level sensor unit and
+through terminal 4 (Gasoline engine models) or 1 (Diesel engine models) of the fuel level sensor unit
+to combination meter terminal 20 (with tachometer) or 35 (without tachometer) for the fuel gauge.
SPEEDOMETERNJEL0042S04The combination meter provides a voltage signal to the vehicle speed sensor for the speedometer.
The voltage is supplied
+from combination meter terminal 23 (with tachometer) or 37 (without tachometer) for the speedometer
+to terminal 1 of the vehicle speed sensor.
The speedometer converts the voltage into the vehicle speed displayed.

WATER TEMPERATURE GAUGENJEL0442S04The water temperature gauge indicates the engine coolant temperature. The reading on the gauge is based
on the resistance of the thermal transmitter.
As the temperature of the coolant increases, the resistance of the thermal transmitter decreases. A variable
ground is supplied to terminal 32 (*1) or 20 (*2) of the combination meter for the water temperature gauge.
The needle on the gauge moves from ªCº to ªHº.
TACHOMETERNJEL0442S05The tachometer indicates engine speed in revolutions per minute (rpm).

+to combination meter terminal 30 (*1) or 22 (*2) for the tachometer.
FUEL GAUGENJEL0442S06The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
+from body grounds M28 and M67
+through terminals 26 and 27 (*1) or 9 and 10 (*2) of combination meter,
+through terminal 1 of the fuel level sensor unit and
+through terminal 4 of the fuel level sensor unit

+to terminal 1 of the vehicle speed sensor.
Ground is supplied
+from body grounds M28 and M67
+through terminals 25 and 27 (*1) or 10 and 11 (*2) of combination meter
+to teminal 2 of the vehicle speed sensor.
The speedometer converts the voltage into the vehicle speed displayed.
