2003 HONDA INSIGHT ignition

If the indicator comes on repeatedly,
even though it may turn of f as you
continue driving, have your vehicle
checked by your dealer as soon as
possible.
Your vehicle 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 the indicator comes on
while driving, it means one
of the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage. If your vehicle’s battery has been
disconnected or gone dead, these
codes are erased. It can take several
days of driving under various
conditions to set the codes again.
To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malf unction indicator lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive times, the readiness
codes are not set. If possible, do not
take your vehicle f or an emissions
test until the readiness codes are set.
Refer to
for
more inf ormation (see page ).
If you have recently ref ueled your
vehicle, the indicator coming on
could be due to a loose or missing
f uel f ill cap. You will also see a
‘‘TIGHTEN FUEL CAP’’ message on
the multi-information display.
Tighten the cap until it clicks at least
once (see page ). Tightening the
cap will not turn the indicator of f
immediately; it can take several days
of normal driving.
You will also see a ‘‘CHECK
EMISSION SYSTEM’’ message on
the multi-information display. For
more inf ormation, see page .

If you keep driving with the
Malf unction Indicator Lamp on, you
can damage your vehicle’s emissions
controls and engine. Those repairs may
not be covered by your vehicle’s
warranties. This indicator may also
come on with the ‘‘D’’ indicator.

However, if the brake pedal does not
f eel normal, you should take
immediate action. A problem in one
part of the system’s dual circuit
design will still give you braking at
two wheels. You will f eel the brake
pedal go down much f arther bef ore
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
Slow down and pull to the side of the
road when it is saf e. Because of the
long distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed and repaired as
soon as possible (seeon page ). If this indicator comes on f or any
other reason, have your vehicle
inspected by your dealer. There may
be a malfunction with the electric
brake distribution (EBD) system.
Avoidhardbrakingandhighspeed
driving.
If the f luid level is low, take your
vehicle to a dealer, and have the
brake system inspected f or leaks or
worn brake pads. If the brake system indicator comes
on while driving, the brake f luid level
is probably low. Press lightly on the
brake pedal to see if it f eels normal.
If it does, check the brake f luid level
thenexttimeyoustopataservice
station (see page ). The brake system indicator normally
comes on when you turn the ignition
switch to the ON (II) position and as
a reminder to check the parking
brake. If you do not release the
parking brake, the indicator will stay
on, and you will see a ‘‘RELEASE
PARKING BRAKE’’ message on the
multi-inf ormation display. You will also see a ‘‘BRAKE FLUID
LOW’’ or ‘‘CHECK BRAKE
SYSTEM’’ message on the multi-
inf ormation display (see page ).
If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully.
If the ABS indicator comes on with
the brake system indicator, have
your vehicle inspected by your
dealer immediately.89

Determine f rom the chart on pagesand , or the diagram on the
fuse box lid, which fuse or fuses
control that device. Check those
f uses f irst, but check all the f uses
bef ore deciding that a blown f use is
the cause. Replace any blown f uses,
and check if the device works.
Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are of f . Remove the cover f rom the under-
hood f use box located on the
battery (see page ).
Check each of the large f uses in
the under-hood f use box on the 12
volt battery by looking through
thetopatthewireinside.
Replacement of these f uses should
be done by your dealer.Check the smaller f uses in the
under-hood f use boxes and all the
fuses in the interior fuse box by
pulling out each one with the f use

µ If , due to damage, your vehicle must
be towed with the f ront wheels on
the ground, do this:
With the f ront wheels on the ground,
it is best to tow the vehicle no farther
than 50 miles (80 km), and keep the
speedbelow35mph(55km/h).
If your vehicle needs to be towed,
call a prof essional towing service or
organization. Never tow your vehicle
with just a rope or chain. It is very
dangerous.

The tow
truck uses two pivoting arms that go
under the tires (f ront) and lif t them
of f the ground. The other two tires
remain on the ground. The operator
loads your vehicle on the back of a
truck. Start the engine.
Shif t to the D position and hold f or

Improper towing preparation will
damage the transmission. Follow the
above procedure exactly. If you cannot
shif t the transmission or start the
engine, your vehicle must be
transported with the f ront wheels of f
the ground.

To use the towing hook:Remove the cover f rom the f ront
bumper using your f ingers, or pry
it of f using a cloth and a f lat-tip
screwdriver to prevent scratches.
If your vehicle gets stuck in sand,
mud, or snow, call a towing service
to pull it out (see page ).
For very short distances, such as
f reeing the vehicle, you can use the
detachable towing hook that mounts
on the anchor in the f ront bumper.
Remove the towing hook and
wheel nut wrench f rom the tool
case in the cargo area.

The bumpers are not designed to
support the vehicle’s weight.
The steering system can be damaged if
the steering wheel is locked. Leave the

The exhaust emissions controls
include f our systems: PGM-FI,
ignition timing control, exhaust gas
recirculation, and three way catalytic
converter. These f our systems work
together to control the engine’s
combustion and minimize the
amount of HC, CO, and NOx that
come out the tailpipe. The exhaust
emissions control systems are
separate f rom the crankcase and
evaporative emissions control
systems.The emissions control systems are
designed and certif ied to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions
remain low, you should use only new
Honda replacement parts or their
equivalent f or repairs. Using lower
quality parts may increase the
emissions f rom your vehicle.
The emissions control systems are
covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more inf orma-
tion.
The PGM-FI system uses sequential
multiport f uel injection.
It has three subsystems: air intake,
engine control, and f uel control. The
powertrain control module (PCM)
uses various sensors to determine
how much air is going into the
engine. It then controls how much
f uel to inject under all operating
conditions. This system constantly adjusts the
ignition timing, reducing the amount
of HC, CO, and NOx produced.
The exhaust gas recirculation (EGR)
system takes some of the exhaust
gas and routes it back into the intake
manif old. Adding exhaust gas to the
air/f uel mixture reduces the amount
of NOx produced when the f uel is
burned.
The three way catalytic converter is
in the exhaust system. Through
chemical reactions, it converts HC,
CO, and NOx in the engine’s exhaust
to carbon dioxide (CO ), nitrogen
(N ), and water vapor.
