The 5-step trick ...
Heated grips
in 5 steps
Our motorcycle can do more than one might suspect: since most motorcycles use the same control units from the manufacturer, this also applies to the R1200GS(A) and R1250GS(A).
With that we can switch the heated grips from 2 levels to 5 levels.
What do we need for this:
ISTA+ (or another tool to check or clear the fault log)
ESYS - to read and write the coding.
After we have started the programmes, read in the coding of the BCO (or central light control unit) in the FA editor of BimmerUtility and typed ,,step" into the search, the following values have to be changed:

After this step we do the same for the KOMBI3 (our TFT display)
Here the search term ,,heating" takes us to the 5-step adjustment; there you can also make settings for the seat heating, if fitted.

As soon as everything has been written again via NCD coding in E-SYS on both control units, the function is already available. Please always check the fault memory afterwards and clear it if necessary.
Frequently asked questions (FAQ)
You need ISTA+ (to check or clear the fault log), ESYS to read and write the coding, an E-Net cable and BimmerUtility.
The coding is changed in the BCO (central light control unit) under the search term "step" as well as in the Instrument cluster (KOMBI3 / TFT display) under the search term "heating".
After both control units have been rewritten via NCD coding in ESYS, the fault memory of both control units should be checked and cleared if necessary.
