hello all, I have a focus c-max with a few niggles, after you have had an accident that has affected the part front left side of the car, with the consequent breakdown of the injection ecu that the ecu junction near the battery.
the control unit of the derivation ? was taken in the demolition, and even that of injection, the wiring ? been detached from the ugni pin and reconnected to the ecu is the engine that derivation, since in the accident had broken everything. after having lost more? a day in the to connect the wires and place l system, I did the start-up and ? game immediately, with but two problems;
1) indicator light alternator turned on, the alternator ? been replaced why? not load, but it still stays on, with the error in the control unit of the smart charge system.
2) power steering not working, the strange thing here ? the diagnosis is that the power steering that car does not exist, how can it be that ? the only thing that does not ? been touched since ? on the opposite side of the dell crash) not ? be able to diagnose the ecu and steering.
checked all the wires for the steering are ok and also supplies and ground, wire line can also.
Not knowing just fine on these machines, I saw that the wires of the can line is the engine control unit (pcm ) of the steering wheel are connected together and all go, and two in the instrument panel .
can it be that the ecu has a sw is different from the original and give me these two problems?
and that the diagnosis of the steering always passes from the engine control unit?
do you have any idea?
thanks

The ecu that you have found has the same numbers of your own?

mail the references of the two ecu, the wiring harness ? been reconnected for good? in the diagnosis of errors are you from?

now c'? the under hand , however, tonight as I write this, however, the number of the bosch ? the same, but this is that ford no.
the wiring harness ? been checked and re-checked and ? everything is ok
codes faults are u1900 and u2510
in the engine control unit c'? the failure on the intelligent charging, but now I don't know the code fault, why? the made to diagnose with a computer, ford

Check the numbers hardoware and software bosch should be the same... If you are only with wardoware and possible that he will be the problem, just rewrite the flash with the software with the same number of the first... The ford number is not ? important x, which often replaces it with an updated one, but the same in features and functions

the original me ? remained only a piece of the carcass, with the number of the bosch and ford.
how can I see what kind do hardware may have?
however, if the number of the bosch ? the same, the ecu should be the one? maybe you just need to update the software...
and then also, according to you, the problem is the battery indicator that the power steering, it can depend on everything from the ecu?

I don't think that it is a problem of soft but most of the communication between the engine control unit, alternator, and therefore does not work the power steering me ricontrollerei well the wiring if I'm not mistaken, the control unit must pull on the alternator with a signal of the shema in the hand recheck everything

but with the diagnosis u2510 (E510) Error in the data security for the car. exits when the battery ? download.
Checking the voltage in the ecu

this morning I tried the control unit with the same codes for bosch and the same code ford, the same problem for the power steering.
I don't know if c'? someone who know well the management of the ford, but the instrument panel ? type of a body computer, right?
therefore, the information all depart from them I guess, so if I can not make the diagnosis of the steering wheel ( not within the diagnosis of the problem ?:
1) connecting wires, which have been checked and are fine
2) the control unit steering skipped
3) instrument panel that communicates with the steering.
right?
anyone know where I can remedy the shemi electric car? I would not like the ones that I have given are not right... now I don't know anymore what to think.

Test with ******** there should be patterns or vivid

These cars are subject to a malfunction of the alternator....
Of course its malfunction results in a series of exclusions...first of all, the electric power steering cesser? of work.

checks to see if the thin wire that goes to the terminal D+/IND/THE alternator comes the positive when you turn the key in the gear.
you can also detach it and bring you momentarily positive with a wire wheel to "trigger" the alternator and see if it loads (the cio? reaches 14V nominal) motor in motion. Even if they write in the manual that exceeded 2000g/min of the engine should load the same due to the residual magnetism in the rotor...
let us know!

hello to the thread that you say, what? the red comes the positive, and the alternator is charging 13.5 v fixed .

In this type of alternator there is a plug three-way, where we find:

1:red Wire that will be? the thread of excitement " D+ ",which is necessary to the rotor finch? can generate even at low engine speeds, the magnetism,the fields, external hard turn in amperes and volts.Here, we will always find a positive fixed +30 protected by a fuse..

2:the Blue Thread Transmits to the engine control unit, the signal charge in Volts,in the form of a square wave, positive digital,with a constant frequency,where the value in volts sar? given by the real height " Width " of the square wave

3:Grey Wire Also transmits to the engine control unit,the signal of the charge but in this case, in ampere,in the form of square wave, positive digital,at a constant frequency,where the value of the amperage will be? given by the width percentage of the square wave or duty cycle..

ok, so the 2 and the 3 are practically the control of the voltage and the current delivered by the alternator...

then, the control unit of the smart charge if it detects 13.5 volts ignite? the light why? ? under the charging voltage (the famous 14V) and there we are..

Determined, therefore, that the red wire to the D+ on the positive side, I have to say that the problem ? the regulator of the alternator..
With the loads (lights, air conditioner, disappanamento..) how to adjust the voltage? remains fixed at 13.5? up to a p??

watch now c'? the under hand, why?he is making a diagnosis a workshop ford in the vicinity, but for what I have said to them , the problem would be the engine control unit to re-encode, since you do not ? the original, taken in the demolition, but codes are the same now.
I have been told ford that the ecu see a load of 13.5 v fixed, but I don't know if speeding up always remains so.
it can be that the ecu then not hearing the famous 14v to manage the battery indicator and always remains turned on the light?

might just be cos?, at least ? a hypothesis that I do, in my opinion you have to proceed step by step when you have several problems..
however, if ? a centre of serious and prepared, should give you the right indications, since they will know well how it works is the ecu smart charge..

these two codes are one battery to the other framework tools
