    07 Freightliner got ABS-E (D+) by Wabco, made in Wrozlaw, Poland. This unit is used on EU and NA trucks, according ECE laws if rear wheels lock ABS unit MUST disable brake retarder, engine brake (exaust flap ore jakes).

    So they install retarder relay. its contacts are used for engine "jakes off" inputs. But now they use J1939 communication. Sometimes after ABS ECU swap this code appeares till u disable retarder relay and activate J1939 with Wabco ToolBox software.

    MID 219 is Collision Avoidance Radar, may be VORAD Radar, may be MB Distronic......
    well 248 - no communication with radar senor. 002 and 009 - erratic data from radar

    There is a small relay on the front of the pdm on the dash, that gets flipped around a lot. Pull your relays one by one straight out, and see if the middle pin on the relay match with the pin in the relay holder

    Yep, when you open the cover, the relay will be one of the small ones, closest to you in the middle (ish) pull it straight up and check the orientation of the pins.
