2003 HONDA S2000 battery

You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run.Your car has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page ).
A key that is not properly coded
will cause the immobilizer system
indicator in the dash panel to blink
rapidly.
Check these things:
Diagnosing why your engine won’t
start f alls into two areas, depending
on what you hear when you press
the ENGINE START button.
When you press the ENGINE
START button, you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at all. Turn the ignition switch to ON (II).
Turn on the headlights and check
their brightness. If the headlights
are very dim or don’t light at all,
the battery is discharged. See
on page .
Press the ENGINE START button,
then release it. If the headlights do
not dim, check the condition of the
f uses. If the f uses are OK, there is
probably something wrong with
the electrical circuit f or the
ignition switch or starter motor.
You will need a qualif ied
technician to determine the
problem. (See on page .)

There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See on page .
Do you have f uel? Turn the
ignition switch to ON (II) for a
minute and watch the f uel gauge.
The low f uel level warning light
may not be working, so you were
not reminded to f ill the tank. Are you using the proper starting
procedure? Ref er to on page .
If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of the
battery and terminal connections
(see page ). You can then try
jump starting the car from a booster
battery (see page ).
In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you press the
ENGINE START button, but the
engine does not run.

Open the hood and check the
physical condition of the battery
(see page ). In very cold
weather, check the condition of
the electrolyte. If it seems slushy
or like ice, do not try jump starting
until it thaws.
If your car’s battery has run down,
you may be able to start the engine
by using a booster battery. Although
this seems like a simple procedure,
you should take several precautions.
To jump start your car, f ollow these
directions closely:

A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
If a battery sits in extreme cold, the
electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

CONT INUED
Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the metal projection
near the intake manifold as shown
in the illustration. Do not connect
this jumper cable to any other part
of the engine.
Connect one jumper cable to the
positive ( ) terminal on your
Honda’s battery. Connect the
other end to the positive ( )
terminal on the booster battery.
Turn of f all the electrical acces-
sories: heater, A/C, stereo system,
lights, etc. Put the transmission in
Neutral and set the parking brake.

Start your car. If the starter motor
still operates slowly, check the
jumper cable connections to make
sure they have good metal-to-
metal contact.
Once your car is running, discon-
nectthenegativecablefromyour
car, then from the booster battery.
Disconnect the positive cable f rom
your car, then the booster battery.
Keep the ends of the jumper
cables away from each other and
any metal on the car until all are
disconnected. Otherwise, you may
cause an electrical short.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle.
The numbers in the illustration show
you the order to connect the jumper
cables. 7. 6.

BOOSTER
BATTERY

This indicator should come on when
the ignition switch is ON (II), and go
out af ter the engine starts. If it
comes on brightly when the engine
is running, it indicates that the
charging system has stopped
charging the battery.By eliminating as much of the
electrical load as possible, you can
drive several miles (kilometers)
before the battery is too discharged
to keep the engine running. Drive to
a service station or garage where
you can get technical assistance.
Immediately turn of f all electrical
accessories:radio,heater,A/C,
cruise control, etc. Try not to use
other electrically-operated controls
such as the power windows. Keep
the engine running and take extra
care not to stall it. Starting the
engine will discharge the battery
rapidly.

CHARGING SYSTEM INDICATOR

Your car has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If your car’s battery has been
disconnected or gone dead, these
codes are erased. It takes several
days of driving under various
conditions to set the codes again.If possible, do not take your car f or a
state emissions test until the
readiness codes are set. See State
Emissions Testing on pages and
. 260
