Cat Electronic Technician ,How can use ET in CAT machinery.

 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
