david Posted January 24, 2023 Share Posted January 24, 2023 (edited) hello im new to the forum, can I ask for help please ? I have a non running bmwr1200gs , I bought the bike as a non runner its got a ews fault , so ive looked on line and most people with this fault replace the key antenna (uncoded) which I have tried bought a new one still same fault , so then I bought the motoscan app and a obdlink mx to read the codes there were loads a fault codes on it , the bike spins over but no start , anybody out there any idea , I did wonder if any body has an old working BMSK (ECU) to try to see if the motoscan app sees it then I would know its a wiring issue? ive tries tracing out the wires from the antenna to ecu and they buzzed out ok HELP PLEASE Edited January 24, 2023 by david Quote Link to comment Share on other sites More sharing options...
Stu Posted January 24, 2023 Share Posted January 24, 2023 Hi and welcome I think this is caused by a flat battery in the alarm system (dwa) Quote Link to comment Share on other sites More sharing options...

Stu Posted January 24, 2023 Share Posted January 24, 2023 No the alarm system has a back up battery inside it these fail and can produce the same fault Quote Link to comment Share on other sites More sharing options...
