A couple of errors...

[SlimPickens]

I noted in the diagnosis, two cars, two errors now recurring.

On Mito 1.3 8DF: P0621 - GENERATOR short-CIRCUIT TO ground-INTERMITTENT appears always in the cold season, no abnormality or a spy.

Rpm: 961 rpm
Water temperature: 3,50 ?C
Battery voltage: 11,087-Volt
Voltage injectors: 48,972 Volt
Quantity? total diesel: 10,125 mm?/the
Air mass measured: 334,5 mg/i
Atmospheric pressure: 978 mBar
Pressure turbocharger measured: 956 mBar
Measured position turbo: 0,070 mm
Measured position EGR: -0,438 mm
Opening the solenoid valve, butterfly: 8,94 %
Air temp (turbo): 4,50 ?C
Air temperature mass air flow sensor): 7,00 ?C
Command glow plugs: 23,40 %
Regeneration of the particulate filter (only for version with DPF): Off
Valve exclusion exchanger EGR: Inserted


On Point 1.3 6JF: P0504 - BRAKE SIGNAL

here I have not saved the DTC, but I remember that was with the engine off and the engine is not cold


Some considerations about it? :confused:

Suffer from the cold as well..;)

but where are you?
and to say that I'm complaining of winter from my parts..azz

Be my friend Turin and another world... in a good way of course..
apprate the cold I believe that much more? developed and civil of so many other countries that I know of..
pane to your problem I don't know answer..
perhaps, and visions of the power of the battery due to the cold..
or next to the short circuit of the quest.

[SlimPickens]

The battery has almost 4 years, but I remember that the error he had detected the mechanic already? at the first oil change. Between the other ? a heavy-duty start&stop, me to? I always keep disabled. Signals barely has never data, perhaps measured at rest is not ? its maximum (12.3 and/or 12.4). In theory ? without maintenance, but under the label, I catch a glimpse of the cover that should cover the caps. I'd be tempted to see if ? can check the ****llo, but I would not like to do damage on a thing that in fact works. Possibly the ispezioner? end-of-life for myself to settle on the next...

[elettro72]

Rpm: 961 rpm
Battery voltage: 11,087 Volts are not a p? pochini? are you sure that the alternator loads, right?

[SlimPickens]

In fact, I can think of one thing... once the engine has started, the tension was immediately around 14,3, but sometimes I have noticed that remains at that peak for a couple of seconds... Must be l? that manifests the problem...

[elettro72]

in fact, the voltage must stay on 14 volt.......... pu? be the regulator or maybe if you is a p? casino the freewheel pulley on the alternator that is going to.....

[SlimPickens]

No, noise is not I feel. Pu? be the electrical part that remains numb in the first few seconds? The error speaks for? of a short circuit. If scollegassi the detachable testing, and possibly by spraying a little bit of reactivating the electric? Even if not, I think it's easily accessible...

[Alfiuccio]

well actually 11 v I know a few I would try with a test at full load if the alternator loads well.....

[SlimPickens]

But 11volt ? the voltage at the moment of starting the engine, then immediately goes to 14.3 except in some cases in which it remains at 11 for a couple of seconds, maybe even you. In that instant, the alternator is not charging. In march anyway ? always correct, even with several users turned on.

[elettro72]

then the alternator ? ok, you had written....
Rpm: 961 rpm
Battery voltage: 11,087-Volt

[sergiot]

to evaluate the alternator is not can you give us the measurement of the voltage in the start-up phase. not ? significant to your problem.
if you are there even 2 seconds ? important.
this pu? happen when the battery ? little charge.
if for? it also happens in gear, it means that the battery is slam, may soon be broken.

[SlimPickens]

Yes yes sorry, I have not specified it for granted, those are the values recorded at the time when the error is encountered. It remains to understand why every so often begins to load after a moment, it would not be anything if it wasn't that, it detects it as a fault... As I said above, if it does ? with the cold, now that I've found. Pu? be a welding imperfect somewhere?

cos? ? pi? clear.
according to me ? the symptom is that the battery ? too low or that does not take into pi? the charge.
prepares another battery.
in the meantime, if you have a charger, put it under load immediately.

[SlimPickens]

[sergiot]

you will not have a battery that is too small?
use oil as prescribed, or other type of oil ? with regard to the 5w... or 10w... ?

[SlimPickens]

nonono everything scrupulously as prescribed, selenia oil 5w30 changed the max to 15 thousand km, the battery (63ah 450a) though ? still the original (but in fact does not even 4 years on the machine). They are pretty manic, I would say, but I also know that a car lives and must be appreciated with its small mysteries and defects.

[sergiot]

maybe you have already? tried to give the key and wait for 3-4 sec, the framework makes the check before start and the spark plugs in ending the heating? does it change something?
I understand that ? a stick on the glass, I do not even I, but I don't have your problems.

[SlimPickens]

[rts]

But you can't do a test with a simple tester and see how many volts charging the alternator?

[SlimPickens]

Cio?? I see that the engine is running I have a voltage of 14.3 volts. What other tests can I do?

[sergiot]

the alternator must be good cos

[yannsaba]

The error that you are presented, and in the early phase after the start-up probably the most? due to some electrical fault has occurred which such a defect in the alternator or the battery. I ? presented a similar problem in the workshop with a peugeot with the bsi, which was a mess with the energy savings. I had them for a few seconds after start-up, only the voltage of the battery generandomi a series of problems, including often also the off the car..

[cele]

You have the battery gone, replace with a new one and you'll see that the problem disappears!

[SlimPickens]

If I was not the one who play with the diagnosis, I would not have noticed anything, abnormalities, or lights I have, so I think that the terr? finch? death (I hope) do us part. Stands for? a question: it should be replaced with a specific start&stop or can I do without it? Of course, with the device perpetually disabled, unfortunately I have found...

[cele]

Unfortunately for you why? costichia it should be replaced with a specific start&stop
