U2101 Control Module Configuration Incompatible on Audio Control Module

Hi all,

On my 2014 Ford F-150 5.0L V8 I have made some changes to the Sync 2 config. I have chaned the language to Dutch and have changed the radio frequency to EU standards. All works flawelessly.

When I read the DTC's from the car I get: Code: U2101 - Control Module Configuration Incompatible

The error is from the Audio Control Module. I thnk this could be some wrong settings in my config. Maybe I need to change RDS settings or something like that.

Could someone have a look at the attachment and review if these settings are correct for usage in the EU, The Netherlands in particular.

TIA

There is already bit of discussion on this issue: https://www.forscan.org/forum/viewtopic ... 0&start=10

Did you take backup of your original Sync 2 config before doing any modifications? If you did, just return it to default and see if that clears the Audio Control Module DTC's. You might need to remove battery lead for some time to get the ACM to reset properly after making changes.

I think your ACM is reading the Sync 2 config and problems arise from difference at tuner region bytes. In ACM configuration there are also settings for EU region, 727-04-01 x*xx xxxx xxxx. You need to change that before Sync settings because ACM will lock up when you get U2101 DTC and you cannot do any changes before it has been cleared.

Thanks for pointing me to that thread.

Yes, I do think it is due to tuner region settings because I have changed the tuner to tune to EU frequencies but nothing else. So RDS is not working for example. I think I also did not change the country code to The Netherlands because I don know the code,

Does anyone know the country code for The Netherlands and how to enable RDS?

All country codes are ASCII letter combinations. NL is 4E4C

Yours is set to 5553 which corresponds to US

Any other you can google with "ASCII table" and finding the corresponding (hexadecimal) values.

Thank you, I'll try. Maybe the U2101 will also disappear then because I use EU frequencies on a US config!

OK, I've changed the country to NL. The DTC does return after clearing it. So that doesn't help. Also, RDS still does not work.
