Technical Any electrical experts out there? Weird fault code U0019.

[Googlebot]

Having a play with Multiecuscan after my recent issues.

This fault came up, it isn't new, its been there for a total of 293 days so I think that would be when it left the converters.

It is a Hymer Motorhome on a Ducato 2.3 250 facelift, 2013.

So, ignore and carry on, or what won't work? I haven't noticed anything wrong and nothing is playing up?

Does anyone know?

Did you clear it and see if it came back ?

Yes, came straight back. Not sure if you can see the time it’s been there on the screenshot, totals 290+ days so I think it left the converters with the error.

It has no tailgate or drivers door as it’s a motorhome so several of the body functions will have been removed or altered at Hymer.

I am suspicious if they have chopped something not required and left it as is.

Possibly for windscreen rain sensor on base vehicle before conversion

Ah yes, also that, though I didn’t think it had automatic wipers.

An example is the external temp sensor, normally in the mirror, mine is on the front crossmember just glued in place with a huge long lead to it with metres of spare all cable tied up.

The more I think about it, the more I am leaning towards, turn the computer off and forget it.

Not worth going back to the convertors?

So Can Line B is one of the two network connections the car uses to communicate between the various modules. So there will be two wires Can line A and Can line B going in and out of each module.

The fact that it is showing as intermittent and it lists what to me seems like a very low battery voltage, it could be that somewhere in the car this can line is shorting to ground (this is logical guess work)

generally for more serious faults such as something being missing you would get a flashing mileage on the odometer, which is the car's way of signaling that it is really not happy.

Chances are that during the conversion the line or wire has gotten trapped or has been pulled loose from a connecting plug. This could literally be a needle in a haystack job for someone to track down.

you say its a 2013 van, but mention it leaving the convertors less than a year ago, so what this an old van that was converted into a motor home? this bit has me confused.

What sort of conversion has it had done? if it is just a van and they have decked out the back with a living area, there are unlikely to be can lines in the back, and would be more likely to run in a loom under the van.
If it has had water tanks installed or waste tanks it is possible they could have pinched a wire under the van, they could have damaged something when feeding wires through from the engine bay, or a favorite is installing an aftermarket radio, and not fitting an adaptor to the wiring loom as fiat use two of the connections in a normal car radio ISO plug for Can lines.

Unless some kind of resister blank connector to fit different front seats, but usually that throws up an ABS fault.

Sorry, I may not have been clear on this. It’s a Hymer Motorhome converted from new. It’s 11 years old, adding up the minutes the fault is present gave me 290+days in total so I am presuming it’s been there a very very long time.

Fiat use two of the connections in a normal car radio ISO plug for Can lines.

Thanks, the radio isn’t original and it has been butchered for accessories like a dash cam, 12v accessory socket and wiring changed all over the place. The same goes for the rest of the van, very little of the wiring through the body is original Fiat.

I was thinking it’s a bit pointless looking for a fault as everything works and as you say, given the conversion, it could be anywhere.

Mate had an Iveco van he took the tacho out of when he converted it, wouldn’t select 5th and 6th gear. Took it to Iveco and it was the missing tacho causing the issue. Mind boggling.

Thanks for your help.

that will have been done to stop people speeding,

It was a well known trick years ago to pull the fuse on the tachograph and that would kill and speed limiters, but you can’t speed if you can’t select higher gears.

290+ days doesn’t even cover the last year, so it’s not really possible to say how long it’s been there. What you have said is that there are lots of changes to the wiring so that’s likely to be where the issues are

Is that not the total time the fault is there in minutes rather than the clock time? I suppose I could reconnect the computer and check?

My thinking was it meant 290 days in total engine on?

Now trying to think what I changed 290 days ago.

This is not specific to the engine, it is likely that you are right about it being more related to use than minutes of time since the error appeared but it is possibly more, time that the electrical systems are switched on, which on a van can be on for long periods without the engine running or without going anywhere. So I would be inclined to not be to worried about that recorded time.

How many miles are on the van? It would potentially be a quite high mile van if that were the total engine running time since leaving the converters

It has done 70,000 on the odometer. We have owned it since 24,000 miles.

Yep so that running time is likely to relate to at least the time that the ignition is on, which accounts not just for the miles covered but every traffic jam, every layby stop and every time it was parked up with ignition on.
