Some non-CAN models like the K1200 GT/LT/RS allow you to calibrate the Tank Reserve Light (the amount of fuel remaining in the tank at which the Tank Reserve Light will switch on).
GS-911 does not have a pin populated at pin position 3. This is the pin that is used to calibrate the Tank Reserve Light.
The following procedure should work on all models ranging from 99-05:
- Empty the thank and fill it with 4 liters (or your desired quantity).
- Make sure you have access to the diagnostic port of the Motorcycle and identify pin 3 and pin 4. If it has no pin 3, this procedure will NOT work.
- Turn the ignition on.
- On the diagnostic port, short pin 3 (brown/black) and pin 4 (brown) for two seconds. (make sure you have the CORRECT pins - you don't want to short Battery voltage to GROUND by mistake).
- The thank reserve light should flash quickly. When the flashing ends, the calibration is complete.
