Hello,
A couple of things.
I have been lead to believe the R1200GS can only support one pair of sensors.
The R1200GS Adventure can support the two pairs of sensors.
Now for a question from me, how did you get the TS401 to read and wakeup the sensors?
I can only find entries for the BMW cars, no bikes in the TS401 configuration.
Thanks,
Geoff
