Warnings
and
Cautions
For
personal
safety,
as
well
as
the
protection
of
sensitive
electronic
components,
the
following
warnings
and
cautions
should
be
adhered
to
when
working
on
the
engine
manage-
ment
system
.
GENERAL
WARNING
-
"
The
ignition
system
produces
high
voltages
that
can
be
fatal
.
Avoid
contact
with
exposed
termi-
nals
.
Use
extreme
caution
when
working
onacar
with
the
ignition
switched
on
or
the
engine
run-
ning
.
"
Do
not
touch
or
disconnect
any
high
voltage
ca-
bles
from
the
coils
or
spark
plugs
while
the
engine
is
running
or
beingcranked
by
the
starter
.
"
Connect
and
disconnect
the
DME
system
wiring
and
test
equipment
leads
only
when
the
ignition
is
switched
off
.
"
Gasoline
is
highly
flammable
and
fts
vaporsare
explosive
.
Do
not
smoke
or
work
on
a
car
near
heaters
or
other
fire
hazards
when
diagnosing
and
repalring
fuel
system
problems
.
Have
a
tire
extinguisher
avaílable
in
case
of
an
emergency
.
"
When
working
onan
open
fuel
system,
wear
suit-
able
hand
protection,
asprolonged
contact
wfth
fuel
can
cause
illnesses
and
skin
disorders
.
"
Renew
fuel
system
hoses,
clamps
and
O-rings
any
timethey
are
removed
.
"
Before
makingany
electrical
tests
that
require
the
engine
to
be
cranked
using
the
starter,
disable
the
ignition
system
as
described
in
120
Ignition
System
.
CAUTION-
"
Prior
to
disconnecting
the
battery,
read
the
bat-
tery
disconnectinn
cautions
given
at
the
front
of
this
manual
onpage

"
Do
not
connect
any
test
equipment
that
delivers
a
12-volt
power
supply
to
terminal
15
(+)
of
the
ig-
nitioncoil
.
The
current
flow
may
damage
the
ECM
.
In
general,
connect
test
equipment
only
as
speclfied
by
BMW,
this
manual,
or
the
equipment
maker
.
"
Only
use
a
digital
multlmeter
for
electrical
test
.
"
Only
use
an
LED
test
light
for
quick
tests
.
"
Disconnecting
the
battery
may
erase
fault
code(s)
stored
in

.
Check
for
fault
codes
prior
to

To
prevent

system
fuel
pressure
should
be
relieved
before

.
One
method
is
to

NOTE-
"
OnM44
engines,
a
Schrmder
valve
is
integrated
in
the
fuel
rail
.
Compressed
air
pressure
canbe
applied
at
the
valve
to
force
the
fuel
in

system
back
into

.
If
the

arenot
available,
a
length
of

and
a
T-fitting

.
On
some
vehicles,
thisis
not
possible
without
cutting
finto

.
In
these
lnstances,
it
Is
recom-
mended
that
fuel

be
checked
at

WARNING
-
"
Gasoline
is
highly
flammable
and
its
vapors
are
explosive
.
"
The
fuel
pressure
gauge
must
be
securely
con-nected
to
prevent
it
from
coming
loose
under
pressure
.
NOTE-
"
The
fuel
pressure
gauge
should
have
arangoof
0
to
5
bar
(0
to
75
psi)
.
"
On
6-cylinder
engine,
thetop
left-sido

cover
will
have
to
be
removed
to
access

.
Residual

testing
For
quick
restarts
and
to
avoid
vapor
lock
when
the
engine
is
hot,
the
fuel
injection
system
is
designed
to
retain
fuel
pres-
sure
after
the
engine
has
been
turned
off
.
Thís
residualpres-
sure

primarily
maíntained
by
a

and
the
