SYSTEM DESCRIPTION
Vehicle speed sensorEVehicle speed
ECM
ECooling
fan
relay(s)Engine coolant temperature sensorEEngine coolant temperature
Air conditioner switch
EAir conditioner ªONº signal
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, air con-
ditioner system pressure and air conditioner ON signal. The control system has 3-step control [HIGH/LOW/
OFF]. This system indirectly relates to diagnostic trouble code 28 (Overheat).
Operation
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.
Malfunction is detected when ...Check Items
(Possible Cause)
lAn excessive high engine coolant temperature sensor sig-
nal is detected by the ECM. (Overheat)lHarness or connectors
(The cooling fan circuit is open or shorted.)
lCooling fan
lRadiator hose
lRadiator
lRadiator cap
lWater pump
lThermostat
lFan belt
lEngine coolant temperature sensor
For more information, refer to ª12 MAIN CAUSES OF
OVERHEATINGº, EC-CD-95.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the MA
section (ªChanging Engine Coolantº, ªENGINE MAINTENANCEº). Also, replace the engine oil.
a. 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 (ªAnti-freeze Coolant Mixture
Ratioº, ªRECOMMENDED FLUIDS AND LUBRICANTSº).
b. After refilling coolant, run engine to ensure that no water-flow 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:
157kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
Pressure should not drop.
CAUTION:
Higher than the specified pressure may
cause radiator damage.
OK
ENG
Check the following
for leaks:
lHoselRadiatorlWater pump
Refer to LC section
(ªWater Pumpº).
CHECK RADIATOR CAP.
Apply pressure to cap with a tester.
Radiator cap relief pressure:
Standard
78 - 98 kPa (0.78 - 0.98 bar,
0.8 - 1.0 kg/cm
2, 11 - 14 psi)
Limit
59 - 88 kPa (0.59 - 0.88 bar,
0.6 - 0.9 kg/cm
2,9-13psi)
OK
ENG
Replace radiator
cap.
CHECK THERMOSTAT.
1. Check valve seating condition at normal
room temperatures.
It should seat tightly.
2. Check valve opening temperature and
maximum valve lift.
Valve opening temperature:
76.5ÉC (170ÉF) [standard]
Maximum valve lift:
More than 8 mm/90ÉC
(0.31 in/194ÉF)
3. Check if valve is closed at 5ÉC (9ÉF)
below valve opening temperature.
For details, refer to LC section
(ªThermostatº).
OK
ENG
Replace thermostat.
Check engine coolant temperature sensor.
Refer to ªCOMPONENT INSPECTIONº,
EC-69.
OK
ENG
Replace engine cool-
ant temperature sen-
sor.
If the cause can not be isolated, go to ª12
MAIN CAUSES OF OVERHEATINGº 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 instru-
ment 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 ªOVERALL FUNCTION CHECKº.

SYSTEM OPERATION CHECK
Set voltmeter between glow plug and engine body.
1. Pre-glow control system
a. Turn ignition switch to ªONº position.
b. Read voltage.
Voltage:
Battery voltage for an engine coolant temperature
dependent time.
* Repeatedly turning the ignition switch to ªONº
position and to ªLOCKº position may change
the pre-glow time.
2. After-glow system
Start engine and read voltage.
Voltage:
Battery voltage for 5* minutes
* Engine coolant temperature is lower than 50ÉC
(122ÉF).
COMPONENT INSPECTION
Glow relay
1. Check relay for coil continuity between glow relay terminals
p1andp2.
Continuity should exist.
2. Check relay for proper operation by applying 12V dc voltage
between glow relay terminals
p1andp2and checking con-
tinuity between terminals
