the fiat bravo is not part of the problem can line

[robby51039]

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

[robby51039]

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

[robby51039]

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

[Backgroop]

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

[robby51039]

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

[Backgroop]

In what units can you make the diagnosis??

[robby51039]

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'???
