HOW TO DIAGNOSE
GENERAL
CHECKING RELAYSM1001004900152
1. By using a relay, a heavy current can be turned on and off by
a switch using much less current. For example, in the circuit
shown here, when the switch is turned on (closed), current
flows to the coil of the relay. Then, its contact is turned on
(closed) and the light comes on. The current flowing through
the switch is much less than that for the light.
2. When current flows through the coil of a relay, its core is
magnetized to attract the iron piece, closing (ON) the
contact at the tip of the iron piece. When the coil current is
turned off, the iron piece returns to its original position by a
spring, opening the contact (OFF).
3. Relays may be classified as the normally open-type or the
normally closed-type, depending on their contact
construction.
NOTE: The deenergised state means that no current is flow-
ing through the coil. The energised state means that current
is flowing through the coil.
(1) The normally open-type
When a normally open relay as illustrated here is
checked, there should be no continuity between terminals
3 and 4 when the relay is deenergised. There should be
continuity between terminals 3 and 4 when battery
voltage and ground are applied to terminals 1 and 2. The
relay condition is determined by this check.
NOTE: Check the relay in both situation which is
energised and is not energised.
(2) The normally closed-type
When a normally closed relay as illustrated here is
checked, there should be continuity between terminals 3
and 4 when the relay is deenergised. There should be no
continuity between terminals 3 and 4 when battery
voltage and ground are applied to terminals 1 and 2. The
relay condition is determined by this check.
NOTE: Check the relay in both situation which is
energised and is not energised.

ENGINE COOLING DIAGNOSIS
ENGINE COOLING14-4
INSPECTION PROCEDURE 2: Engine Overheating
DIAGNOSIS
STEP 1. Remove the radiator cap and check for coolant
contamination.
Q: Is the coolant contaminated with rust and oil?
YES : Replace it. Refer to P.14-27.
NO : There is no action to be taken. Go to Step 2.
STEP 2. Check the radiator cap valve opening pressure.
NOTE: Be sure that the cap is clean before testing. Rust or
other foreign material on the cap seal will cause an improper
reading.
(1) Use a cap adapter to attach the cap to the tester.
(2) Increase the pressure until the gauge indicator stops
moving.
Minimum limit: 83 kPa (12 psi)
Standard value: 93
123 kPa (14 18 psi)
Q: Does the reading remain at or above the minimum limit?
YES : Go to Step 3.
NO : Replace the radiator cap. Then go to Step 5.
STEP 3. Check thermostat operation.
Refer to 38.
Q: Does the thermostat operate correctly?
YES : Go to Step 4.
NO : Replace the thermostat, then go to Step 5.
STEP 4. Check the drive belt for slippage or damage.
Refer to GROUP 00, Maintenance Service
Drive Belts
(Check Condition). <3.8L Engine>39 .
Q: Is the drive belt loose or damaged?
YES : Adjust or replace the drive belt, then go to Step 5.
NO : There is no action to be taken.
STEP 5. Retest the system.
Check the engine coolant temperature.
Q: Is the engine coolant temperature abnormally high?
YES : Return to Step 2.
NO : The procedure is complete.

INSTALLATION SERVICE POINTS
.
>>A<< O-RING INSTALLATION
Do not allow engine oil or other grease to adhere to the
O-ring
Insert the O-ring to the water pipe, and coat the outer portion of
the O-ring with water or engine coolant.
.
>>B<< ENGINE COOLANT TEMPERATURE
SENSOR INSTALLATION
Apply the specified sealant to the thread of the engine coolant
temperature sensor, and then tighten it to the specified torque.
Specified Sealant: 3M
AAD Part No. 8731 or equiva-
lent
.
>>C<< RADIATOR UPPER HOSE CONNECTION
1. Insert each hose as far as the projection of the water outlet
fitting.
2. Align the mating marks on the radiator hose and hose
clamp, and then connect the radiator hose.
INSPECTIONM1141003400337.
Water Pipe and Hose Check

>>C<< FUEL HIGH-PRESSURE HOSE
INSTALLATION
Be careful not to allow any engine oil to enter the fuel
rail.
Be careful not to bend the fuel high-pressure hose as it
is made of plastics.
1. When connecting the fuel high-pressure hose to the fuel rail,
apply a small amount of new engine oil to the O-ring and
then insert the fuel high-pressure hose, being careful not to
damage the O-ring.
2. While turning the fuel high-pressure hose to the left and
right, install it to the fuel rail.
3. Check that the injector turns smoothly. If it does not turn
smoothly, the O-ring may be trapped. Remove the fuel
high-pressure hose and then re-insert it into the fuel rail and
check again.
INSPECTIONM1151003100672
Check the following points; replace the part if a problem is
found.
.
Intake Manifold Check
1. Check for damage or cracking of any part.
2. Clogging of the negative pressure (vacuum) outlet port.
3. Using a straight edge and feeler gauge, check for distortion
of the cylinder head installation surface.
Standard value: 0.15 mm (0.006 inch) or less
Limit: 0.20 mm (0.008 inch)

ASSEMBLY SERVICE POINTS
.
>>A<< REGULATOR ASSEMBLY INSTALLATION
After installing the regulator assembly, insert a wire through the
hole provided on the rear bracket while pressing down on the
brush, and secure the brush.
NOTE: By inserting a wire, the brush will be secured in place,
and the installation of the rotor will be easier.
.
>>B<< ROTOR ASSEMBLY INSTALLATION
After installing the rotor, remove the wire used to secure the
brush.
INSPECTIONM1161001700099.
ROTOR CHECK
1. Check the continuity between the slip rings of the field coil. If
the resistance value is not within the standard value, replace
the rotor.
Standard value: approximately 2

2. Check the continuity between the slip ring and the core. If
there is continuity, replace the rotor.
.
STATOR CHECK
1. Check the continuity between the coil lead. If there is no
continuity, replace the stator.
2. Check the continuity between the coil and the core. If there
is continuity, replace the stator.
.
RECTIFIER CHECK
1. Check the continuity between the positive rectifier and the
stator coil lead connection terminal with a tester. If there is
continuity between the terminals, the diode is shorted, so
replace the rectifier.

CHARGING SYSTEM
ENGINE ELECTRICAL16-19
2. Check the continuity between the negative rectifier and the
stator coil lead connection terminal with a tester. If there is
continuity between the terminals, the diode is grounded, so
replace the rectifier.
3. Check the continuity of the three diodes by connecting an
ohmmeter to both ends of each diode. If there is continuity
between the directions, or if there is no continuity, the diode
is damaged, so replace the rectifier.
.
BRUSH CHECK
1. Replace the brush if the brush protrusion length shown in
the illustration is below the minimum limit value.
Minimum limit: 2 mm (0.08 inch)
2. The brush can be removed by unsoldering the brush lead
wire.
3. When installing a new brush, push the brush in to the brush
holder, and solder the lead wire.
