I recently updated my Sync 2 to a Sync 3 by way of a Chinese kit now running Sync v3.4. No issues with the audio system so I thought. I decided to run a scan using ForScan and said software shows the following error:
APIM U2101:00-0B
Code: U2101 - Control Module Configuration Incompatible
Status: (-0B)
-DTC Present at Time of Request
-Malfunction Indicator Lamp is Off for this DTC
Module: Accessory Protocol Interface Module
Since I’m new to the Ford world I will be the first to say I have no clue how to go about fixing this error. My car is a 2013 Ford C-Max Hybrid SEL
I contacted the Chinese seller about the error I was getting on ForScan. They replied:
“U2101 can be ignored. After upgrading from SYNC 2 to SYNC 3, the system recognized that the hardware was different, resulting in an error. It will not affect the use of any functions. All SYNC 2 upgrades to SYNC 3 will have this fault code due to the hardware changes made.”
I can confirm that there are no problems with the operation or function of the equipment in regards to that error code.
