Hi All,
I have a 2002 R1100s (iABS), The bike has a long term defect that I am attempting to resolve.
When riding the bike the speedo doesn't work, and the Brake failure light flashes at 1 Hz.
Servo function is fine,GS911 shows no faults, and was very useful for testing the wheel sensors -so it has paid for itself already.
The rear wheel sensor was not showing wheel speed when the rear wheel is turned, However when I jump the rear wheel sensor to the front wheel electrical circuit- it is working, Hence the sensor & it's air gap are correct
I have continuity between the rear wheel sensor up to the ABS Plug, And I can feed a pulsed signal from the ABS plug to the speedo And I get a speedo reading. This seems to point to an issue with the plug connection or internal electronics of the ABS modulator. Then this bit really beats me - About a month ago I rode the bike home in 40 deg C heat first gear for 20km on the freeway(not by choice),And yes everything fired up & ran perfectly for the next 7 km, before going back into it's coma.
Short of waiting for further global warming any further guidance would not go unheeded.
Thanks,
Uncle.
