In this bolog i'm going to tell
you how to connect to
and use caterpillar electronic
technician for your engine or equipment
so before i start you how to
actually use ,,ET,, i want to discuss a
little bit about
ET itself and the
software that caterpillar produces
for basically any other technicians or a
customer to be able to communicate with
their engine their machine
and see what the codes are see what the
sensors are reading
do certain diagnostic tests on it this
is the software you have to use there's
pretty much no other cat software out
there for this type of thing now there
are
after-market scanners and stuff but ET
works
the best for your cat equipment anyone
can download et it's about a 500
megabyte file
to their computer however it doesn't
work unless it is
licensed the license determines
what version of ET basically you have so
i'm going to be showing you
basically a customer version there's
about 20 different licenses out there
there's truck only
there's taps there's military there's
all different
types of versions but the most common
are dealer and
customer version now the point of this
bolog is to tell you
the basic layout of ET so ET does not
work by itself you're going to need some
sort of com adapter i recommend the
command after three which is
cat's actual com adapter you can always
use
nexic products there's a variety of com
adapters
and if you're gonna be plugging into a
truck you're gonna need a different
adapter to go from the com adapter to
the truck there's an obd2 style
there's a nine pin there's a nine pin
green
and there's a six pin so this takes the
nine pin black although the green will
work in the black or the green
and you should get a power light on even
with the key off
when you first plug in if you don't you
probably have a problem with
the vehicle itself or the battery to the
com adapter
when you turn et on and it's trying to
communicate you should be getting
at least one blinking light this is an
older truck so it's communicating on
the j1708 also called the 1587.
newer vehicles typically they're going
to have j1939
and 1708 so this is et
itself when you first connect or
at least boot up the program this is
where you're gonna see now
mine is set to not automatically connect
i have to click connect and then it will
try to look for an ecm
and if it finds one it's going to
connect to it
when you first connect this is the
screen you're going to get this
is basically a quick snapshot of
information about
your machine or engine now if it's a
piece of machinery that has multiple
control modules they're going to be
displayed on the left this is a truck
engine so long as one
ecm and that's displayed on the left
it's also going to show the serial
number.
now it's going to give you some basic
information like that the serial number
it's going to tell you the date and the
time of the ecm.
personality module code vehicle id stuff
like that
bottom left, we have active codes and
status flags you can click on those
and we're going to now go to the status
screen
so the status screen will tell you what
sensors are reading
also it will tell you inputs and outputs
so if your
exhaust break or your jacobs break was
set
on it would show you what it's set to if
it's reading properly
now look at our accelerator pedal
position i just pushed it it went from 3
to 68.
notice the min max as long as you're on
the screen it will
keep the minimum and maximum once you
change screens though in the status
screen to a different status group
it's going to reset the minimum and
maximum from that previous screen
and it'll erase them forever but it'll
now start recording
minimum and maximum for the current
screen.
now the status groups are preset but you
can if you want to
under groups there on the bottom left
preset certain
parameters notice i have eui engine
regen
and huey engine under custom status
groups the full screen button will
display,
one through i believe eight sensor
readings,
as a full screen instead of these little
lines it's really helpful if you're
trying to watch
one or two now notice the region one
didn't have many that's because this is
a non-region
engine so it's only going to show
sensors that this engine has it's not
going to show sensors
that the engine doesn't have makes sense,
now let's go to active diagnostic codes
this has no active diagnostic codes but
if a data would be displayed there,
if it had any log diagnostic codes this
would be displayed there
there are no active events if there were
i'd be able to click on it,
logged events is going to be displayed
here now notice this has
logged events j1939 device not
responding
that's a data link code there's probably
something wrong with dash control
module or abs module something like that,
now notice in the bottom there
it says troubleshoot code if you click
on that either in the logged or active
events or diagnostic codes
it's going to take you to either
something called component
component-based troubleshooting or it's
going to try to log you into sys, which
is cat's service information system
getting et does not give you access to
those,
notice you can see the current
diagnostic clock and then the amount of
occurrences and the first and last time
that occurred ,now we'll get back to our
little information center here like i
said before there's going to be more
information on the left if it has
multiple ecms which just does not
let's go to our configuration. so we're
in configuration now
now configurations where you can start
messing stuff up if you don't know what
you're doing
notice all the configurations are
collapsed you can expand them, and
view what information you want the first
one's going to have like your engine
rating and stuff so if you expand all
it's going to be all.
the programmable features let's try to
find the vehicle speed limit
that is under vehicle speed parameters
and it's on the very top line there
vehicle speed limit go up to 127 miles
an hour however if you try to change it
you may require factory password or a
customer password.
now if you get to the bottom these are
very important hey which is some ls and
fts do bro for uh
for like the most horsepower so the fls
and fts and your personality module code
should not be
changed unless you're a dealer and doing
a par dyno they are set at the factory
on the dyno
please don't mess with them just because
you think you're going to get
a bunch more horsepower better fuel
economy more doesn't mean better there's
actually an fls and fts map.
and i do not recommend messing with it
now what we're
scrolling over here is winflash winflash
is how you program an ecm but we're not
going to be doing that because it's a
separate program file
i do have a bolog though on how to
program an ecm you might want to check
that out if that's what you're trying to
do
now under diagnostics there's a lot of
features and unfortunately they're not
popping up like i said for my
um software here but there's one called
critical events this is different than
the logged events the critical events
would be like a very high overheat
also under diagnostics. we're going to
have our diagnostic tests
which you couldn't see but it's there so
these are the available diagnostic tests
for the engine and injector solenoid
check
special test cylinder cutout test let's
go to cylinder cutout test
if you were trying to do a cylinder
cutout test obviously this is where you
would want to be,
now notice the engine is not running we
have zero
engine speed but you can still mess
around with it do cut out tests
you can actually do injector solenoid
test too that's also under diagnostics
if you're having electrical problems.
now we're going to be going to service
and then we're going to go to ecm date
and time
it's there trust me so this will enable
you to change the ecm date and time a
lot of the time it is not
accurate this one's actually an hour
ahead we could
change that if we want to but this
vehicle is actually it runs in a
different time zone so we're just going
to leave that alone
next we're going to go into service and
then calibrations.
that is where you do injector trim
calibrations
these are your injector trim files
now just like the fls and fts you should
not be changing your injector trim files
to just an arbitrary number, they should
match what is actually on the injector
those are there from the factory for a
reason it's supposed
to let the injectors in the engine run
at optimal levels please don't mess with
your injector trim files leave them what
they're supposed to be,
now there's a feature called the trainer
which is this little guy in the blue
with the line
if you don't know how to use ET and
you're just reading this bolog because
you have no idea what you're doing
you can disconnect from the ecm and then,
click on the trainer
now show you a bunch of different
engines and machines you can click on in
the trainer mode
and what it's going to do is it's going
to fake connect
to one of these machines or engines and
then it's going to let you do
tests like a cylinder cutout test change
parameters
and look it's showing that it's
connected to an sdp which is a cat truck
engine,
but it's really not it's also going to
show you that the engine's running you
can do different tests see it's 773 rpms
but you're not actually connected to
anything
so you could do any sort of injector
cutout test
you could do fake timing test change
configuration whatever you want to do
you're not hurting anything because it's
an
actual feature of this software please
use this
if you're unfamiliar with how to use ET
you'll learn a lot
now while it's doing this fake injector
cutout test what it's looking for in a
cutout test
is a lower number meaning that the
engine doesn't have to increase the fuel
to make up for that cylinder not firing
now the downside with the trainer is of
course you're not actually hooked up to
a new engine so you're not going to be
able to do,
real troubleshooting where you can
actually hear the engine running
hear a tone change when a cylinder cuts
out things like that but
on the other side is you can't damage
anything
or break anything or try to change a
parameter not be able to change it back
and there's a lot of features to ET and
i'm
i would say very good on the truck
engine side but on the equipment side i
have very little knowledge
so there's a lot of features ET even i
don't know how to use and i've been
using it for 8 years just because i'm
kind of a specialist when it comes to
engines
i could spend an hour discussing 18 and
showing all these different features of
it
but this is meant to be just a beginner
basic
okay i plugged into it what the heck do
i do type training
a true training would be pretty much all
day you could spend an entire day easily
on ET especially of a machine or an
engine to hook up to
now this cylinder cut out this fake
cylinder cutout test is uh coming to an
end here and we're not finding any
fake dead cylinders here so
bolog knew i was working on a c13 that
had some pretty bad cavitation in the
cylinder liner number five
now here's the number five liner and you
can see that hey
yes it is cavitated people were
surmising that perhaps
it was just this one liners a casting
problem, but
the other liners also had cavitation
what i say is bad no not quite as bad
but some of it had it in more places
this one had it around the top
area this one also had it in a line you
can see
it was pretty deep on this one as well i
believe that was number two
number one also had some pretty deep
holes it's hard to see the depth here
but pretty much all the liners had
pretty bad cavitation hey look a twofer
so this is a 3208 this is also a teaser
to our next video
328 this is the most dirt and junk i've
ever seen
in an engine so this is in the valley
here looks like something like sasquatch
was shedding in here or something
but look at the amount of dirt in this
intake oh my gosh
it's like an eighth of an inch thick
with dirt i
it i've never seen this much dirt in the
intake something
horrible maintenance wise been going on
with this engine
thanks for reading .keep enjoy
