With the ignition in the on/run position, the receiver will monitor, demodulate and decode transmission at 315MHz, sent from the wheel-mounted pressure sensors. Tire pressure problems are reported to the driver via light emitting diodes on the dashboard. A separate system will illuminate the LED’s. Tire information is sent to this separate system using a high speed CAN bus.

Summary

Tests
for
compliance
with
FCC
Regulations
Part
15,
Subpart
B,
and
Industry
Canada
RSS(210/GEN,
were
performed
on
TRW
model/PN(s)
218143(108,
218143(109,
218143(110.
This
device
is
subject
to
the
Rules
and
Regulations
as
a
Receiver.
As
a
Digital
Device
it
is
exempt,
but
such
measurements
were
made
to
assess
the
receiver's
overall
emissions.

In
testing
completed
on
July
13,
2007,
the
device
tested
in
the
worst
case
met
the
allowed
Class
B
specifications
for
radiated
emissions
by
9.7
dB
(see
p.
6).
The
conducted
emissions
tests
do
not
apply,
since
the
device
is
powered
from
a
12
VDC
system.

3.ConfigurationandIdentificationofDeviceUnderTest

3.1DesignandIdentificationoftheDevice The
DUT
was
designed
by
TRW
Inc.,
24175
Research
Drive,
Farmington
Hills,
MI
48335(2642.

It
is
identified
as:

TRW
Receiver

Model/PN(s):
218143(108,
218143(109,
218143(110

FCC
ID:

GQ4(38R

IC:

1470A(10R

3.2Models There
are
three
(3)
models
of
the
device.

The
different
model
numbers
send
different
CAN
bus
messages
over
the
harness
to
the
automobile,
but
all
are
electrically
identical.
The
DUT
is
a
315
MHz
superheterodyne
receiver,
designed
for
onboard
automobile
security/convenience
applications,
and
as
such,
it
is
powered
from
an
automotive
12
VDC
source.

It
is
housed
in
a
plastic
case
approximately
3
by
4
by
1.5
inches;
antenna
is
internal.

For
testing,
a
generic
harness
was
provided
by
the
manufacturer.

In
the
receiver
digital
section,
the
decoding,
signal
processing,
etc.
are
performed
by
a
microprocessor
timed
by
an
10.0
MHz
oscillator.
