Acura MDX - 2003 Fuse Box Diagram

Acura MDX - 2003 Fuse Box Diagram

The power window system has a key-
off delay function. The windows will
still operate for up to ten minutes
after you turn off the ignition.
Opening either front door cancels
the delay function. You must turn
the ignition switch ON (II) again
before you can operate the windows.
If the driver’s window runs into any
obstacle while it is closing
automatically, it will reverse
direction, and then stop. To close the
window, remove the obstacle, then
use the window switch again.
Auto reverse stops sensing when the
window is almost closed. You should
always check that all passengers and
objects are away from the window
before closing it.
If your vehicle’s battery is
disconnected or goes dead, or the
driver’s window fuse is removed, the
AUTO function will be disabled. The
power window system needs to be
reset after reconnecting the battery
or installing the fuse. You should do
the following.
Any impact due to road conditions
may cause the auto reverse function
work unexpectedly on the closing
window. If it happens frequently,
there is a problem with your power
window system. You should have
your car inspected by your dealer.
You can still close the window by
pulling back on the window switch
lightly and hold it.
If the power windows do not operate
properly after resetting, have your
vehicle checked by a Acura dealer.
Start the engine. Push down on
the driver’s window switch until
the window is fully open.
Pull back on the driver’s window
switch to close the window
completely, then hold the switch
for a second or two more.

Diagnosing why your engine won’t
start falls into two areas, depending
on what you hear when you turn the
key to START (III):
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
faster than normal, but the engine
does not start up and run.
When you turn the ignition switch to
START (III), 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.
Check these things:
Check the transmission interlock.
The transmission must be in Park
or Neutral or the starter will not
operate.
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
.
Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the fuses. If
the fuses are OK, there is proba-
bly something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. (See
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 connec-
tions (see page
). You can
then try jump starting the vehicle
from a booster battery (see page
).
In this case, the starter motor’s
speed sounds normal, or even faster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run.
Are you using the proper starting
procedure? Refer to
on page
.

To jump start your vehicle, follow
these directions closely:
If your vehicle’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.
Put the transmission in Neutral or
Park, and set the parking brake.
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.
Turn off all the electrical acces-
sories: heater, A/C, climate
control, stereo system, lights, etc.
You cannot start your Acura by
pushing or pulling it.
Your vehicle 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.
Do you have fuel? Turn the
ignition switch to ON (II) for a
minute and watch the fuel gauge.
The low fuel level warning light
may not be working, so you were
not reminded to fill the tank.
There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses
(see page
).
If you find nothing wrong, you will
need a qualified technician to find
the problem. See
on page
.

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 freeze.
Attempting to jump start with a frozen
battery can cause it to rupture.
If the electric motor will not close
the moonroof, do the following:
Check the fuse for the moonroof
motor (see page
). If the fuse
is blown, replace it with one of the
same or lower rating.
Try closing the moonroof. If the
new fuse blows immediately or the
moonroof motor still does not
operate, you can close the
moonroof manually.
Get the moonroof wrench out of
the tool kit in the cargo area.
To remove the round plug in the
center of the headliner, turn the
plug by using a screwdriver or
coin, then pry it out. Make sure to
align the tabs on the round plug to
the notches on the ceilling as
shown in the illustration.
Insert the moonroof wrench into
the socket behind this plug. Turn
the wrench until the moonroof is
fully closed.
Remove the wrench. Reinstall the
round plug.

All the electrical circuits in your
vehicle have fuses to protect them
from a short circuit or overload.
These fuses are located in three fuse
boxes.
The interior fuse boxes are located
underneath the dashboard on each
side.
To open the fuse box on the
passenger’s side, pull the right edge
of the cover.

PASSENGER’S SIDE INTERIOR
If something electrical in your
vehicle stops working, the first thing
you should check for is a blown fuse.
Determine from the chart on pages
and
, or the diagram on the
fuse box lid (the diagram for the
driver’s side interior fuse box is on
the kick panel below the fuse box),
which fuse or fuses control that
component. Check those fuses first,
but check all the fuses before
deciding that a blown fuse is not the
cause. Replace any blown fuses and
check the component’s operation.
Turn the ignition switch to LOCK
(0). Make sure the headlights and
all other accessories are off.
Remove the cover from the fuse
box.
The secondary fuse box is in the
engine compartment next to the
battery.
The primary under-hood fuse box is
located in the back of the engine
compartment on the passenger’s side.
To open it, push the tabs as shown.

Look for a burned wire inside the
fuse. If it is burned, replace it with
one of the spare fuses of the same
rating or lower.
Check each of the large fuses in
the primary under-hood fuse box
by looking through the top at the
wire inside. Removing these fuses
requires a Phillips-head screw-
driver.
Check the smaller fuses in the
under-hood fuse box and all the
fuses in the interior fuse boxes by
pulling out each fuse with the fuse
puller provided in the primary
under-hood fuse box.

If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem in your vehicle.
Leave the blown fuse in that
circuit and have your vehicle
checked by a qualified mechanic.
If the radio fuse is removed, the
audio system will disable itself. The
next time you turn on the radio you
will see ‘‘
’’ in the frequency
display. Use the Preset buttons to
enter the five-digit code (see page
).
If you cannot drive the vehicle
without fixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
from one of the other circuits. Make
sure you can do without that circuit
temporarily (such as the accessory
power socket or radio).
If you replace the blown fuse with a
spare fuse that has a lower rating, it
might blow out again. This does not
indicate anything wrong. Replace the
fuse with one of the correct rating as
soon as you can.

Replacing a fuse with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a replace-
ment fuse with the proper rating for the
circuit, install one with a lower rating.
