have had a look in the archives, but no results for ECU Error Code 56 here in the forum so far.
My GRiSO, during the summer, is under a cover, in Croatia, with some torrential rain every now and then. It happened to me this summer twice that after some rainy days, with the good weather returning, I take my GRiSO out for a ride and the speedometer is not working and of course the warning red triangle appears.
After a few days of hot, dry weather, the error disappears, the speedometer shows again. As said, this has now happened twice.
Both times I checked the ECU error codes. It was 'ECU Error Code 56 Vehicle speed'. It seems like that the vehicle speed sensor must have a bad contact.
Can anyone tell where to find this Vehicle Speed sensor? I guess somewhere around the wheel hub?
Many thanks for any help
