Technical MES can’t find Com 1

[DaveMcT]

I’ve had a right old time with the diesel cylinder head. Another story. Another time.
It’s now running but engine warning light is on.
A long time ago I got MES to work but that computer
is dead. I’ve just installed MES on a Windows 11 laptop and it runs fine.
HOWEVER when I try connecting to the car with a USB adapter, MES says “Cannot find COM1”
I don’t want to screw up the laptop so how do I deal with this issue? can’t find anything in the MES forums.

What com port does it say the adaptor is installed on in device manger

 

[DaveMcT]

I’ve opened device manager? What do I need to look for?
Adapter is plugged in car ignition is on etc

 

[DaveMcT]

Computer says USB is on com 3 just found it

Yes it's best to

But it depends on the chipset used, the adaptor look identical

There two different common types

One the LED normally only comes one when plugged into the car and laptop

The other will come on with just the laptop


Which type is yours

Computer says USB is on com 3 just found it

Change MES to com 3 and try

 

[DaveMcT]

I changed the USB to Com1 and MES connected. Yay!
It seems to expect Com1.
However MES says the car ECU is not responding. The car starts so that’s odd.

 

[DaveMcT]

OK. So I have a connection but need to choose the correct engine ECU. 2010 Multijet is not listed. Any ideas?

 

[koalar]

Nope don't have a 2010 multijet to test

Does it pass the MES

Adapter test

 

[DaveMcT]

This is the ECU sticker. Maybe I need to choose a different Fiat eg 500.

 

[koalar]

6JF is supported under



Fiat
Panda '03
1.3 JTD/Multijet

With

KL or ELM V1.3 or newer

 

[koalar]

Latest free version does according to there website

 

[koalar]

Any elm comparable software will work to read engine codes

AlfaOBD for PC should also work with you interface

 

[DaveMcT]

Thanks. It’s looking like my interface is faulty. I’ll look into sorting why it is not playing nice.
Bugsy Mike came over and we used his professional kit to read codes, read pressures, switch relays, etc. I’ve still got no start. I’ll start a new thread on that.

"professional kit" Dave?
By the way this is that old fuel rail I mentioned.

 

[DaveMcT]

Your mechanic's touch screen computer is way better than my MES and wonky OBD interface. ;-)

If that fuel rail sensors etc. look similar you are welcome to try them,the fuel unions are the leaking ones I mentioned though. Roughly 06 1.3MJ Grande Punto (first of that shape)

 

[PuntoHowTo]

You shouldn't have to configure all this manually. I've not used it for a while now but I always used to search for the adaptor, then let MES search and find all the modules ? has this changed a lot recently ?

I am using quite an old version of MES

 

[The Panda Nut]

Not all engines are listed inside MES apparently some engine numbers not included but if you select the correct car and engine it will work. My 2019 Panda comes back with this error. I contacted Gendan and they explained that whiel not all specific engine codes are included it will still work. Indeed it does. Being a bit OCD it irritates me but if I relax and go with it all is well. Once MES connects to the right COM port it seems to function OK thereafter. I had the same problem connectingto a DOblo. when a member wanter a small job done. We said go to the MES adjustment when it appeared to accept the car / connection and again it did the job.
