Multiecuscan

Hi, i want to upgrade my old odometer (Ducato 250, 2017) to new one virtual from 21.
scan and reading at old one no problem, everything works,
but when i connect the new odomeeter to the car, i can not connect with Multiecuscan,
i try serveral Models, but comes errors like: Time out error, check cable + port, can`t connect to Body Computer.
somebody an idea ?

Early 250 Ducato models only needed basic ELM support for the Instrument panel. Later models require adapter A3

250 Facelift and 290 model

Ducato (type 250) : Instrument Panel Marelli |INFO|DTC|DTC EX|PRM|ACT|ADJ| ELM

Ducato (type 250) Facelift : Instrument Panel Marelli |INFO|DTC|DTC EX|PRM|ACT|ADJ| ELM | A3

Ducato (type 290) : Instrument Panel Marelli |INFO|DTC|DTC EX|PRM|ACT|ADJ| ELM | A3

MES will not prompt for adapter A3 if you select your earlier 250 model.

In MES select try selecting the 250 Facelift or 290 model.

Hi, i done it like you describe, i try 250 +290 facelift, ELM + Adapter A3, scan + connection + proxi no Problem when the old odometer
is connectected to the car, only when i connect the new odometer to the car i get the errors , no connection

Sorry to hear this.

I must leave this to others now who are probably far more experienced than me in using MES with "out of normal configuration" operations and connections.

Thinking about this I suspect that your vehicle does not have the wiring to support the later instrument panel.

same cluster connectors don't mean pin out is the same on old and new clusters. check wiring diagrams.
