Hello everyone, I come from Austria, Burgenland. 🙂
I'm new here and I'm glad I came to this forum. 🙂

I would like to buy an FFE 2018.
I visited such a model (about 650km away from me) and test drove it (up to Vmax 145km/h) (100% - 25% in ~100km).

When I started the CCS charging, the charge station (with screen) shows up with the error message "Communication error".

I tried several other charging stations several times and none of them charged CCS.

Charging with AC at the charging stations works.

On some charging stations with a screen you can see the progress.

Car is recognized
Authentication is carried out,
Loading parameters are transferred,
Cable connection is checked and
at the end...
Charging process is being prepared.


Most of the time the “communication error” occurs (when the car is locked)
during or after “Charging process is being prepared”.

If I leave the car open and plug it in, the communication error often occurs earlier in the process.

Unfortunately I couldn't buy the car because I have a very long travel time without charging CCS.

However, I don't want to give up the car because I really enjoyed driving it (sometimes with tears in my eyes while driving).

The car dealer was unable to successfully diagnose Ford because they were not very familiar with the model.

I would like to try to diagnose and repair the problem myself.

I recently ordered the OBDLink EX USB OBD2 adapter and will use ForScan for this.


Does anyone have any ideas as to what causes this could be?

Kind regards
ManuelW

Not sure what info you'll get over CANBus. CCS has a very complex communication protocol and the EVCC isn't likely to be putting detailed error info out on the bus. Perhaps others have seen more.
 
It sounds like a tricky CCS issue. You might start by checking the onboard charger’s firmware with ForScan, as outdated firmware can cause charging errors.
