Hi there,

this is my first post in this forum.

For an electronic project i bought myself a second cluster of an 500 Sport. So with Shift Indicator in the EVIC...

For this project i want to reuse this cluster as a piece of a desk (clock etc...and some funky things )

My questions are:
What protocol is FIAT using for the 500 gauges: Is it B-Can 11bit/50kbaut like in a Panda?
The most important Question: How is the pinning of the connector on the backside of the cluster?

So there are 14 pins and i only found VCC+, GND and IGN+, PushButton-Signal...

But which pins are for Can-H and Can-L?
Is the Cluster maybe getting the messages over LIN?

Also interessting to me: Is it only able to communicate with the cluster over the body controller (BCM) or can i receive and send CAN-messages directly between my laptop (including Can-Interface (CanCard)) and the cluster?

Thx in advance.

Steve

Is there no Information for this? Or is this forum dead, maybe ?

Hi Steve

This forum is certainly not dead and if anybody can help they will.

However your post does raise an issue regarding technical information.

1) MES developers do legitimately obtain diagnostic protocol information as defined by FIAT at the EOBD port. That port and wiring then goes to the car's body computer and I suspect that this then becomes a closed and propriety information domain only available to the contracted sub unit/node equipment suppliers.

2) The wiring information is fully detailed in official Fiat service manuals which are available for purchase. Sadly in more recent times buying a full Fiat workshop and technical manual for £20/$20/20 Euros has long since passed and currently such documentation will cost you £250/£300Euros at least.

I have always purchased the official service/technical manuals for all the Fiats I have owned but since post 2005 this is no longer a viable option for somebody not in a trading business.

MES are in the business of developing and trading Fiat diagnostic software only.

I hope maybe and independent trader will come to you help but you have to bear in mind that they too have paid large sums of money for technical information so may be unwilling to just pass this on cost free when they could legitimately charge you for their services in this matter.
