Fiat Ducato Instruments Problems

[duzaven]

I have cluster instrument from Boxer ( 1383776080 )On cluster instrument lights are sometimes dimly lit even when the vehicle is turned off the lights remain on causing the battery to go flat.i found and replaced one led diode,but the problem remains

Can you use inferred thermometer see if anything ‘hot’?

[duzaven]

i can try measure component temperature.I also think it's a leak from smd ,and in can bus wrong signal sent.

[Meat-Head]

Don’t think canbus as it goes to sleep and also you send clocks and work on return

Hi, I have the same problem Fiat Ducato with dashboard led small lights abs, airbag, temp max, against fogging, handbrake, small lights is when the dashboard wakes up, the same when driving, these lights do not light up with others, when waking up correctly none is lit ... do they get power from another pcb component ?? smal lights for the moments when I connect only gnd pin 1 and pin 2 +12 on the table, is there any solution ?? I'm sorry for my English

If it is faulty can you put it in a plastic bag, put it in freezer for one hour with power see if anything not frozen?

I had two dashboard org 2009 and I bought a used 2014 two had the same defect but different controls were lit, the new one was bought because the client wanted to run more than 400,000 dash 2014 is already running but there is a fault, heating it in the workshop did not change anything, but it seems I think it was shining more in the cold outside, I have left from 2009 on tests, so in my free time I will check what you say and freeze him

If freezer makes it worse, then slowly warm each part of the board up

[/code] Hmm I didn’t realise it was a fault. I had complained about a dimly lit dash at service time and the dealer fixed it with a software update. 2016 Ducat.[code]

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

I had a dashboard this week here to repair and this post explains everything you need to do!
In my case, 2 leds were faulty(reverse leakage current), replaced, and everything is fine. Tested all led activations via diagnostic, 1 by 1.

For those who are not used to these kind of tests, make sure not to put 3.6v directly in the leds, use a a resistor (100 ohms minimum) on positive lead.

did anyone work out what the led model actually is so you dont have to use second hand ones and can replace as needed?
3528 PLCC 2 3v?
