engine and emission control systems are connected
securely.
• Valve lash is checked according to maintenance
schedule.
• Ignition timing is within specification.
• All accessories (wipers, heater, lights, A/C, etc.) are
out of service.
• Air cleaner has been properly installed and is in good
condition.
• No abnormal air drawn in from air intake system.After all items are confirmed, check idle speed and IAC
throttle opening as follows.NOTE
Before starting engine, place transmission
gear shift lever in “Neutral”, and set parking
brake and block drive wheels.

Step Action Yes No
1Is there DTC(s) of ECT sensor circuit (DTC P0116 / P0117 /
P0118) and/or radiator cooling fan circuit (DTC P0480)?Go to corresponding
DTC flow.Go to Step 2.
2Radiator cooling fan control circuit check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Start engine and select “Data List” on scan tool.
3) Warm up engine until coolant temp. is 100 °C, 212 °F or
higher and A/C switch turns OFF (if equipped with A/C).
(If engine coolant temp. dose not rise, check engine
cooling system or ECT sensor.)
Is radiator cooling fan started when engine coolant temp.
reached above temp.?Radiator cooling fan
control system is in
good condition.Perform from Step 2 to
Step 7 in DTC P0480
diag. flow. If OK, Go to
Ste p 3.
3Radiator cooling fan control check
1) Disconnect radiator cooling fan motor connector with

Diagnostic Information and Procedures
Battery InspectionS6RW0D1A04001
Common Causes of Failure
A battery is not designed to last indefinitely; however,
with proper care, it will provide many years of service. If
the battery performs satisfactorily during test buy fails to
operate properly for no apparent reason, the following
are some factors that may point to the cause of trouble:
• Accessories left on overnight or for an extended
period without the generator operating.
• Slow average driving speed for short periods.
• Electrical load exceeding generator output particularly
with addition of aftermarket equipment.
• Defects in charging system such as high resistance,
slipping drive belt, loose generator output terminal,
faulty generator or voltage regulator. Refer to
“Generator Symptom Diagnosis”.
• Battery abuse, including failure to keep battery cable
terminals clean and tight or loose battery hold down.
• Mechanical problems in electrical system such as
shorted or pinched wires.
Visual Inspection
Check for obvious damage, such as cracked or broken
case or cover, that could permit loss of electrolyte. If
obvious damage is noted, replace battery. Determine
cause of damage and correct as needed.
Generator Symptom DiagnosisS6RW0D1A04002
CAUTION!
• Do not mistake polarities of “IG” terminal
and “L” terminal.
• Do not create short circuit between “IG”
and “L” terminals. Always connect these
terminals through a lamp.
• Do not connect any load between “L” and
“E” terminals.
• When connecting charger or booster
battery to vehicle battery, refer to “Jump
Starting in Case of Emergency”.

Trouble in charging system will show up as one or more
of the following conditions:
1) Faulty indicator lamp operation.
2) An undercharged battery as evidenced by slow
cranking or indicator dark.
3) An overcharged battery as evidenced by excessive
spewing of electrolyte from vents.
Noise from generator may be caused by loose drive
pulley, loose mounting bolts, worn or dirty bearings,
defective diode, or defective stator.

Charging Indicator Lamp Operation
Generator Test (Undercharged Battery Check)S6RW0D1A04003
This condition, as evidenced by slow cranking or low
specific gravity can be caused by one or more of the
following conditions even though indicator lamp may be
operating normal. The following procedure also applies
to cars with voltmeter and ammeter.
• Make sure that undercharged condition has not been
caused by accessories left on for extended period of
time.
• Check drive belt for proper tension.
• If battery defect is suspected, refer to “Battery
Description”.
• Inspect wiring for defects. Check all connections for
tightness and cleanliness, battery cable connections
at battery, starting motor and ignition ground cable.
No-Load Check
1) Connect voltmeter and ammeter as shown in figure.
NOTE
Use fully charged battery.

2) Run engine from idling up to 2,000 rpm with all
accessories turned off and read meters.
If voltage is higher than standard value, check
ground of brushes.
If brushes are not grounded, replace IC regulator.
If voltage is lower than standard value, proceed to
the following check.
Specification for undercharged battery (No-load
check)
Current: 10 A
Voltage: 14.2 – 14.8 V at Hi (H) (at 25 °C, 77 °F)
Voltage: 12.5 – 13.1 V at Lo (L) (at 25 °C, 77 °F)
NOTE
Consideration should be taken that voltage
will differ somewhat with regulator case
temperature as shown in figure.

1) Set parking brake and place automatic transaxle in
PARK (NEUTRAL on manual transaxle). Turn off
ignition, turn off lights and all other electrical loads.
2) Check electrolyte level. If it is below low level line,
add distilled water.
3) Attach end of one jumper cable to positive terminal
of booster battery and the other end of the same
cable to positive terminal of discharged battery. (Use
12-volt battery only to jump start engine).
4) Attach one end of the remaining negative cable to
negative terminal of booster battery, and the other
end to a solid engine ground (such as exhaust
manifold) at least 45 cm (18 in.) away from battery of
vehicle being started.
5) Start engine of vehicle with booster battery and turn
off electrical accessories. Then start engine of the
vehicle with discharged battery.
6) Disconnect jumper cables in the exact reverse order.
With Charging Equipment
CAUTION!
When jump starting engine with charging
equipment, be sure equipment used is 12-
volt and negative ground. Do not use 24-volt
charging equipment. Using such equipment
can cause serious damage to electrical
system or electronic parts.

Battery Dismounting and RemountingS6RW0D1A06002
Dismounting
1) Disconnect negative cable (3).
2) Disconnect positive cable (2).
3) Remove retainer (4).
4) Remove battery (1).
Handling
When handling battery, the following safety precautions
should be followed:
• Hydrogen gas is produced by battery. A flame or
spark near battery may cause the gas to ignite.
• Battery fluid is highly acidic. Avoid spilling on clothing
or other fabric. Any spilled electrolyte should be
flushed with large quantity of water and cleaned
immediately.Remounting
1) Reverse removal procedure.
2) Tighten battery cables securely.
NOTE
Check to be sure that ground cable has
enough clearance to hood panel by terminal.

Water Pump / Generator Drive Belt Tension
Inspection and Adjustment
S6RW0D1A06006
WARNING!
• Disconnect negative cable at battery
before checking and adjusting belt
tension.
• To help avoid danger of being burned, do
not remove radiator cap while engine and
radiator are still hot. Scalding fluid and
steam can be blown out under pressure if
cap is taken off too soon.

1) Inspect belt for cracks, cuts, deformation, wear and
cleanliness. If it is necessary to replace belt, refer to
“Water Pump / Generator Drive Belt Removal and
Installation”.
2) Check belt for tension. Belt is in proper tension when
it deflects the following specification under thumb
pressure (about 10kg or 22 lb.).
If belt tension is out of specification, go to next steps.
