FUEL SYSTEM (PGM-FI)
Mil
Blink Pattern
•
If the HDS pocket tester
is not
available, DTe
can be
read from the
peM
memory by
the MIL blink
panern.
•
The
number
of
MIL
blinks is
the
equivalent
the
main code of the
Ole
(the
sub code
cannot
be displayed
by
the
Mil).
•
The MIL will blink the
current
OTe,
in
case
the
peM detects the
problem at
present,
when
the
ignition switch
ON
or idling
.
The MIL
will
stay
ON when driving (engine speed
is over
2,000
rpm).
•
The MIL
has two types of blinks, a
long blink and
short blink. The
tong blinking lasts
for
1.3 seconds,
the short blinking
lasts
for 0.5
seconds.
One long
blink is
the
equivalent
of
len
short
blinks.
For
example, when two long
blinks
are
followed
by
five
short
blinks,
the
Mil
is
25 (two long blinks = 20
blinks,
plus five
short
blinks).
•
When the PCM
stores
more than one
oTC,
the MIL
will indicate
them by
blinking
i
n
the order from the
lowest
number to
highest
number.

The
OTC
is indicated in
two
ways accord ing
to
the
failure
status.
•
In case
the PCM
detects
the problem
at
present,
the
MIL will
come on and
the
MIL will
start to
blink as
its oTC.
It is
pos-
sible to
readout the MIL blink
pauern as
the
current OTC.
•
In
case
the
PCM does not detect
any problem
at
present
but
has
a
problem
stored in
its
memory,
the MIL
will not
l
ig
ht
and blink.
If
it is necessary
to retrieve
the past problem,
readout the
stored
OTC by following
the
OTC readout
proce-
dure.
