Fiat Ducato Instruments Problems

[JotaB]

probably not mcu becouse my MCU is R5F61544 so this is different group mcu ... one group example NEC i understand but next different mcu the same? dont think so ..probelm is probably connections or components bad

In Fiat I've read in a forum (https://forums.outandaboutlive.co.uk...Problem/45806/) that with a SW revision the problem is solved. Your MCU will have to be programed the same as mine for the warning lights to appear in a correct way! I think it will be so.

And where you find the file to program the mcu?

Find. Working set and leech it

That's the one million dollar question

Yes maybe like that. But used ones are expensive.


You'll FIND the knives and forks in the left-handdrawer.

Or maybe like this. Who knows!!!

Find a set with more miles than a spaceship on them, as long as they work

Bumpage and spamming

Has anyone solved this problem ?

Ok guys i admit, been looking at INFERIOR so called “websites” and dug some useful
information up.

i have washed my hands and hair, wiped my boots etc

INFERIOR SITE

Cartronix repairs were discussed in this recent-ish forum thread relating to an X250 Peugeot Boxer’s problematical instrument-cluster.

{INFERIOR LINK REMOVED}

It will be noted that Cartronix had two ‘goes’ at fixing the problem, initially replacing the cluster’s display and processor, then replacing another ‘electronic component’. After the 2nd repair the cluster worked for 6 weeks, then died, then recovered. A Peugeot agent subsequently found some loose connections (which may have been the cause of the problem to begin with).

The fault described in that thread appears to differ from the well-known ‘dim/spurious warning lights’ issue that is mentioned on this Cartronox webpage

https://cartronix.co.uk/product/fiat...r-dash-repair/

You’ll see that Cartronix say "We replace the faulty parts with new more robust components

ok, the way video shown could be a false representation, near to mcu checks
with meter 2 components, then remove one, yet another’s video is just the lcd on its own

Uppage:-

just rung really nice man at “a k speedo” had a talk about this thread
he is going to join this fantastic forum we have and see if we can get to bottom of it.

Remember therez other threads on this subject linked in above posts

i've the solution for this problem.
problem it's some led are defective.
some led not work pefectly as a diode and negative or positive can pass trought diode led.
for find led defective you can check with a 3.6volt battery, put one alimentation on diode thet thurned on weak( anode or chatode) AND try to put other alimentation on diode connected in series, if you find one diode thet turns on your led on with alimentation on anode and chatode ,you find faulty led

Thanks fra69 .... Did I understand this correctly? You think the dimly lit LEDs are passing a low current circuit 'leak' back through?
So test with 3.6v battery that they should only illuminate/turn on/conduct in 1 circuit direction only!?
(Sorry I don't understand the part " AND try to put other alimentation on diode connected in series " .... Is there another diode in series??)

Please if anyone could clarify my confusion!!

Where is it possible to purchase replacement LEDs for this & other clusters?

Thanks

you can use led from some used cluster. i've many flautly cluster in my warehouse and i use it.
for explain the problem it's easier show you then explain thet.
i've repaired many cluster with this problem.
also golf 6, panda 169, g.punto and other cluster have this problem, but ducato it's most common.

Thanks for the info. I tried to test the led as you stated but when using a 3.6v battery the led blew up. This was on a Fiat 500 speedo which suffers the same problem. Do you know the led ratings for replacement? I know they're 3528 PLCC-2, 20mA. Just unsure of foward voltages and mcd
