2001 Fiat Ducato 2.8 JTD - NO REV COUNTER (1 Viewer)

[zen navigator]

My rev counter has no reading, the speedo, trip all work fine as does all other functions on the instruction panel.

I wonder if any one else has had this problem and how it was resolved?

Thinking it might be a common problem on the Ducato?

I am bracing myself that if I want to repair I will have to replace the whole instrumention panelWhich I guess wont be cheap

It may just be a loose connection...apperantlety there are two fixing screws that hold the lot is and once you have removed those you can disconnect the electrical bit and reconnect it which cures some problems....

Thinking it could just be a loose connection. I have no real idea how the rev counter gets its reading. Is it electro-mechnical or a pulse from a microprocessor.

If the chip option then its going to be a replacement of the unit I guess. If the cable thing then maybe a wiggle will do

Anyone know either way?

Yeh, its not something that is keeping me awake at night. But if its a cheap fix, I like to get it done.

But dont want to necessarily take it to a garage for them to sting me oh:

Good evening.

Did you manage to fix the problem? I have the same on my fiat 2.8 JTD.

I think I'm right in saying that the feed pick up for the rev counter is on the back of the alternator.
That's where I would begin my search.
Its usually the F wire feed that causes the issue, but I'm probably talking crap & I apologise if I am.
Incidentally rev counter inoperative on a diesel can be a sign of alternator failure, but not in all cases.

It depends on whether the engine is common rail. If it is the ECU needs an engine speed sensor that is also used for injector timing and if that's the case the tacho gets its signal from the ECU.

If it is the head unit Cartronix at Waterlooville should be able to repair it.
