2009 Acura MDX headlights

Diagnosing why the engine won't
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:●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.
Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a 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 the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
Jump Starting
on page432.●Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the fuses. If the fuses
are OK, there is probably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. See
Emergency Towing on page446.If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of
the battery and terminal
connections (see page421).You
can then try jump starting the
vehicle from a booster battery (see
page432).
The Starter Operates Normally
In this case, the starter motor's speed
sounds normal, or even faster than
normal, when you turn the ignition
switch to the START (III) position,
but the engine does not run.
●Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page70).

Checking and Replacing Fuses
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
443,444,and445, or the diagram on
the fuse box lid, which fuse or fuses
control that device. Check those
fuses first, but check all the fuses
before deciding that a blown fuse is
the cause. Replace any blown fuses,
and check if the device works.
1. Turn the ignition switch to the LOCK (0) position. Make sure the
headlights and all other
accessories are off.
2. Remove the cover from the fuse box.
3. Check each of the large fuses inthe under-hood fuse boxes by
looking through the top at the wire
inside. Removing these fuses
requires a Phillips-head
screwdriver.FUSE BLOWN
