View The Full Version : the fiat bravo is not part of the problem can line

hi all wonder if someone ever tried this:in these days I went in a shop to check out a bravo 1.4 16v because it is not part of the mechanic thought it was the engine control unit corrupt. I make the diagnosis and to me the agreement of problems on the line can also be failures in the various units,I'll explain. in the ecu that you can diagnose,engine, steering,abs,the other nothing.....
struggle-leadership on the line c-can ok 60ohm and 2.5 v to the mass of the two......
control the line b-can 00ohm and on a 0.5 v on the other 12v!!!!
could be the body party by gateway??
according to you if the body is not dialogue, it is possible that the machine will not start???
asking for advice because they are doubtful if it is the body party 0 the line b-can

hello, the line b-can not measure the resistance, you need to test continuity? and if in short to positive +12 or ground, your problem is definitely in the abs control unit that communicates with the ccm( engine control unit), I would recommend you remove the jack connector abs and do a pote between wires C-can brown with brown and green to green so as to exclude from the network, the abs, controlled well the wiring under the battery holder, c'? a service to the fiat regard to the restoration of the plant due to rubbing with the port battery

it is ok, in fact, a bit, I thought all abs in fact, I esp not available and asr ,but the line c can seem ok 60 ohm 2.5 v mattendo to mass, what do you think?
isn't it strange that on the outlet eobd can I have +12v and 0.5 v?!?!!
these refer to the b-can

oh, I forgot, made test continuity from the outlet to the engine control unit to the socket on the body (line c can) it is ok l h

I would recommend you to exclude all the nodes starting from the abs then the group-electric, etc. leaving only connected to the ccm and in the body, you will know that the control units on the network (c-can) are in series with body-ecu guide-abs-engine control unit, just one of them that transmits evil in the network to give problems

you, I knew that,but having the data as I described in the order I thought that the c can ditch ok
, I did not go back to the situation of a lack of dialogue with the diagnosis if the other control units, in particular, with the body!!
this made me think of the body corrupted that sends the wrong information

In what units can you make the diagnosis??

robby51039
26-11-2013, 13:01
is the diagnosis of the engine, the steering,abs, I semra also strumantazione the rest nothing
namely, the control siagn in line k, and the other can line no

check under the brake lever on the hand,maybe in my case it was a new500,however, if the system ? similar should be the yaw sensor, in my case the wiring was going to end up between the teeth of the brake lever by hand.

also checked this, it was ok I was under the heating near the airbag,ok, strange that as a failure, I always esp,then he tells me,"hill holder" but things'???

check carefully to see what it says obd75 and happened to me twice in the handbrake lever, pulls the plug out-of-control cables are not loose

gero did I mention,the wires in the pettiene you on the runway.
hill holder ? a function always of the esp should be a assistenta for pastenza from a standstill or uphill"should not put my hand in the fire", however, f? part of the esp

though I tried, I pulled the wires on the socket(I happened on the other car) but it's ok
I want to set fire to it!!

do not remain other that to exclude the can line (wires green and brown)how are you ? the state recommended starting at the abs and then to the sens.yaw etc..
if one of the devices disturbs or cancel the signal can all ecu's can not work.

hello can line and so connected: BODY > ELECTRIC DRIVING > NODE YAW> NODE ABS> NODE, the ENGINE control UNIT, the body can't diagnose it? if yes, which dtcs are there? in the other nodes that dtc did you? you can proxare and see which ecu you to configure, and then the problem will be, or in the power supplies of the same or in the links can
shared on the network

thanks so much,this link I had already found and tried(ok) I also put two wires to the right from the body to the ecu the engine to avoid wiring problems
the ecu can not find dtc,in the control unit body does not communicate
today I found out that this car had the battery interotta......this makes me think of strange spikes of voltage in the negative as positive......in the whole network
I think that all that remains is to try to replace the body and the ecu what do you think??

I also believe I will try a body,if you make a diagnosis with the examiner you can see in the monitor the can network which are the units that are active and those that are in error

if the connections to power and ground and can line are ok ( well controlled ) would say to look inside the body or replace it,
have you tried if with jump-starting the machine? or diagnosis?
if you need to do the test with another body, not c'? history.

to me the big question every now and then is out of abs not available,esp not available,esr is not released,hill holder unavailable

I wanted to try jump-starting but with autocom does not, I found a body of a delta the same hw but I can't program the key as the customer has lost the card!!!!
this car has the bad luck inside!!!

you could try to do a scodifica total on the ccm( engine control module), replace the body and give it a try, or dissaldi the eeprom from the body not working and the insert in the working model

Sorry in the meantime, try if you make the diagnosis, both in the body and in the control units in the can, cos? at least eliminate the problem that does not make the diagnosis.
Then in the case scodifichi the body

I tried to make scodifica total but the file is not processed, however, in diagnosis to me from the start-up permission,the body and with the micro, and I don't know how to read it, I don't have a player type upa....

Backgroop

For the scodifica you have to read the file content inside the 95640 soik 8, faila read full bdm separate the affected file and the seats.. otherwise if you have the chance? dissaldi and read the E2prom and places the file

with the 2? body you enter the diagnosis in all the devices?
why? now, if you communicate you might be in the good way....
