FUNDAMENTALS
FOR
THE
DO-ITYOURSELF
OWNER

In
places
where
a
shaft
mustpass
through
a
housing,
flexible
lip
seals
areused
to
keep
the
lubricating
oil
or
grease
from
leak-

ingout
past
the
rotating
shaft
.
Seals
should
never
be
reused

once
they
have
been
removed
.
When
removing
a
seal,
be
care-
ful
not
lo
scratch
or
otherwise
damage
the
metal
surfaces
.
Even
minor
damage
to
sealing
surfaces
can
cause
sea¡
damage
and
leakage
.

The
key
to
sea¡
installation
is
to
get
the
sea¡
in
straight
without

damaging
¡t
.
Use
a
sea¡
driver
that
is
the
same
diameter
as
the
seal
housing
to
gently
and
evenly
insta¡I
into
place
.
If
a
proper
size
seal
driver
is
not
available,
a
socket
of
the
right
size
will
do
.

When
installing
a
seal,
¡t
a
good
idea
to
coat
the
sea¡
with
o¡I

to
aid
installation
.
Some
seals
are
directional
and
special
instal-
lation
instructions
apply
.
Make
sure
¡t
is
installed
with
the
lip
fac-
ing
the
correct
way
.
Normally
the
lip
faces
the
inside
.
Note
the
installation
direction
of
the
old
sea¡before
removing
¡t
.

Wire
Repairs

Repairs
to
a
wiring
harness
requirespecial
care
to
make
the

repair
permanent
.
The
wire
endsmust
be
clean
.
lf
frayedor
oth-

erwise
damaged,
cut
off
the
end
.
If
the
wire
is
too
short,
splice
in

a
new
piece
of
wire
of
the
same
size
and
make
two
connec-
tions
.

Use
connectors
that
are
designed
for
the
purpose
.
Crimped-

on
or
soldered-onconnectors
are
best
.
Crimp
connectors
and

special
crimping
pliers
are
widely
available
.
If
soldering,
use

needlenose
pliers
tohold
the
wire
near
the
solder
joint
and
cre-
ate
a
"heat
dam"
.
This
keeps
the
heat
and
the
solder
from
trav-
eling
up
the
wire
.
Always
use
a
solder
made
specifically
for
electrical
work
(rosin
core)
.

NOTE-

Twisting
wirestogether
to
make
a
repair
is
not
recom-
mended
.
Corrosion
and
vibration
will
eventually
spoil
the
connection
and
may
lead
to
irreparable
damage
to
sensitive
electronic
componente
.

NOTE-

For
some
bigger
jobs,
partial
disassembly
and
inspec-
tion
are
required
to
determine
acomplete
parts
list
.
Read
the
procedure
carefully
and,
if
necessary,
make
other
arrangements
to
get
the
necessary
parts
while
your
car
is
disassembled
.

If
a
battery
cableconnection
hasno
visible
faults,
but
is
still
suspect,
measure
the
voltage
drop
across
the
connection
.
A
large
drop
indicates
excessive
resistance,
meaning
the
con-
nection
is
corroded,
dirty,
or

.
Clean
or

the

and

.

Wiring
and
Harness
Connections

The
electronic
fuel
injection
and
ignition
systems
operate
at

low
voltage
and
current
values,
making
them
sensitive
to

small
increases
in
resistance
.
The
electrical
system
is
routine-

ly
subjected
to
corrosion,
vibration
and
wear,
so
faults
or
cor-

rosion
in
the
wiring
harness
and
connectors
are
common
causes
of
driveability
problems
.

Visually
inspect
all
wiring,
connectors,
switches
and
fuses
in
the
system
.
Loose
or
damaged
connectors
can
cause
inter-

mittent
problems,
especially
the
smallterminals
in
the
ECM

connectors
.
Disconnect
the
wiring
harness
connectors
to

check
for
corrosion
;
and
use
electrical
cleaning
spray
to
re-

move
contaminants
.
Often,
simply
disconnecting
and
recon-

necting
a
dirty
connector
several
times
will
clean
the
terminals
and
help
to
reestablish
good
electrical
contact
.

If
a
wiring
harnessconnectorhasno
visible
faults,
but
is
still

suspect,
measure
the
voltage
drop
across
the
connector
.
A

large
drop
indicates
excessive
resistance,
meaning
the
con-

nector
is
corroded,
dirty
or
damaged
.
Clean
or
repair
the
con-

nector
and
retest
.

Ground
Connections

For
any
electrical
circuit
to
work,
it
must
make
acomplete

path,
beginning
at
the
positive
(+)
battery
terminal
and
ending

at
the
negative
(-)
terminal
.
The
negative
(-)
battery
cable
is

attached
to
the
car's
chassis
.
Therefore,
any
wireor
metal

part
attached
to
the
chassis
provides
a
good
ground
path
back

to
the
negative
(-)
battery
terminal
.

Poorground
connections
are
amajor
source
of
driveabílity

problems
.
If
any
of
themainground
connections
for
the
igni-
tion
system
or
the
fuelinjection
system
are
faulty,
the
in-

creased
resistance
in
that
circuit
will
cause
problems
.

Visually
inspect
al¡
ground
wires
and
connections
for

breaks,
looseness
or
corrosion
.
Be
careful
because
wires

sometimes
break
internally
or
in
areas
not
easily
visible
.
The

main
grounds
for
the
DME
system
are
shown
in
Fig
.

and

.
Also
check
the
main
fuel
pump
ground
in
the
center
console,
below
the
emergency
brake
handle
.

If
a
ground
connection
has
no
visiblefaults,
but
is
still
suspect,

measure
the
voltage
drop
acrossthe
connection
.
A
large
drop

indicates
high
resistance,
meaning
the
connection
is
corroded,

dirty
or
damaged
.
Clean
or

the
connection
and
retest
.

Mass

sensor
(hot

testing
and

When
the
engine
is
running,
a
current
is
used
to
heat
a
thin

wire
in
the
center
of
the
sensor
.
See
Fig
.
25
.
The
current
in
the

wire
is
regulated
to
maintain
a
temperature
of
100°C
more

than
the
air
passing
over
it
.
The
current
used
to
heat
the
wire

is
electronically
conneced
into
a
voltage
measurement
corre-

sponding
to
the
mass
of
intake
a¡
r
.

To
keep
the
wire
clean,
it
is
heated
to
a
temperature
of
about

1,000°C
(1,830°F)
for
one
second
.
This
"burn-off"
cycle
takes

place
automatically,
four
seconds
after
the
engine
is
tumed
off
.

lf
thehot
wire
breaks
or
if
there
is
no
output
from
the
air
flow

sensor,
the
ECM
automatically
switches
to
a
"limp-home"

mode
and
tucos
on
the
Check

light
.
The
engine
can

usually
be
started
and
driven
.
The
air

has
no
inter-

nal

parts
and
cannot

INTERIOR
EQUIPMENT

0013195

The
early
E36
cars
areequipped
with
a
single
(driver
side)
airbag
in
the
steering
wheel
.
Startingwith
the
1994
models,
a
dual
airbag
Supplemental
Restraint
System
has
been
stan-
dard
equipment
.
Side-impact
airbags
in
the
front
doors
are
op-
tional
in
1997
4-door
cars
and
standard
equipment
in
all
1998
models
.

Through
1996,
E36
seatbelts
were
equipped
with
BMW's
original-designspring
tensioners
.
In
1997,
the
seat
base
de-
sign
was
modified
to
accommodate
a
pyrotechnic
(explosive
charge)
seatbelt
tensioner
.
Both
types
of
tensioners
arede-
signed
to
automatically
tension
the
belts
by
about2
inches(55
mm)
in
the
event
of
a
collision
.

The
padded
dashboard
houses
the
instrument
cluster
and
the
ventilation
and
heating
system
.
The
instrument
cluster
uses
large
easy-to-read
analog
instruments
and
is
removable
as
a
unit
without
removing
the
dashboard
.
The
Service
Inter-
val
Indicator
(SII)
will
remind
the
driver
when
thecar
requires
service
.
See
620
Instruments
.

The
Multi-Information
Display
(MID)
unit
in
thecenter
of
the
dashboard
comes
in
a
variety
of
four
configurations,
the
most
advanced
being
the
On-Board
Computer
(OBC)
.
See
Fig
.

.

Al¡
versions
of
the
MID
have
a
clock
and
calendar
.
In
addi-
tion,
different
versions
areequipped
with
a
"check

display
for
fuel-economy

LOCKING
SYSTEM
AND

ELECTRONIC
IMMOBILIZATION

The
central
locking
system
uses
electrical
lock
actuators
at

each
door
and
at
the
trunk
lid
.
The
locking
system
can
be
ac-

tuated
by
either
front
door
lock
or
by
the
luggage
compartment

lock
.
Onsome
1994
and
later
cars,
an
additional
remote
con-

trol
keypadcan
also
be
used
to
activate
the
lock
and
anti-theft

systems
.

When
the
key
is
tuned
to
the
lock
position,
a
micro-switch

signals
a
central
control
module
to
lock
all
doors,
luggage

compartment,
gas
tank
flap
and,
in
later
convertibles,
the

glove
box
lid
.
Where
applicable,
this
also
arms
the
anti-theft

system
.
