This
module
comes
with
our
USB
Field
Upgrade
and
Configuration
Port!
We
recommend
connecting
it
to
a
computer
BEFORE
YOU
INSTALL
and
using
our
support
app
"m4cconnect"
to
do
a
quick
firmware
update
check.
M4cconnect
as
well
as
all
other
information
regarding
USB
update
and
configuration
can
be
found
at
www.mods4cars.com/usb.
You
can
even
configure
and
activate
your
favorite
module
functions
and
settings
on
screen
before
the
module
is
installed
in
the
car!
It
is
a
good
idea
to
permanently
install
the
USB
cable
with
the
module
in
the
car,
leaving
the
computer
plug
in
an
easily
accessible
spot
for
later
use
with
a
Wifi/3G/4G
connected
laptop.
The
green
DATA
LED
signals
a
correct
installation
and
shows
the
status
of
the
module.
LED
OFF
Ignition
OFF:
CAN
bus
and
module
are
in
low
‐
power
standby
mode.
This
is
normal.
Ignition
ON:
Either
power
connection
or
CAN
bus
connection
is
interrupted.
Check
the
two
wire
taps
for
power
and
ground
as
well
as
the
CAN
connectors.
Also
make
sure
the
CAN
polarity
is
correct.
LED
either
dimly
lit
or
flickering
erratically
A
dim
or
flickering
LED
is
an
indicator
for
interrupted
or
missing
POWER
or
GROUND
connections.
The
module
will
get
some
leakage
current
from
the
CAN
bus
which
causes
the
LED
to
stay
dimly
lit
or
flicker
erratically.
See
previous
paragraph
about
wire
taps
if
applicable!

ON
Module
is
connected
to
CAN
and
power,
but
does
not
receive
the
correct
data.
Recheck
all
connections
thoroughly.
A
VERY
COMMON
source
of
problems
is
reversed
polarity
on
the
CAN
wires.
Double
‐
check
the
POLARITY
and
wire
‐
colors
of
all
connections!
