Auto bed leveling crashes RAMPS.

I am very new to 3d printing and this is my first time posting on this form. I apologize if this isn't the right place for this.

I just installed an induction sensor on my printer for auto bed leveling. When I uncomment #define AUTO_BED_LEVELING_FEATURE and upload the firmware to my board the print becomes unresponsive. Nothing shows up on the LCD and my computer wont connect.

If I comment it out and upload the firmware it immediately begins working again.

My firmware works great otherwise.
I am using marlin 1.0.2-1 on a RAMPS board with a heated bed.

Here is my config file: [drive.google.com]
Plz help

I can´t recommend using the ABL-function of marlin 1.02.
The developers are already rewriting this part, but it´s still not working for all of the different printer types.

For instance: They assign pin D32 as input for the z-probe, but this pin isn´t accessible with the smart LCD-adapter mounted on a Ramps.

If you want to play around with ABL ( until it´s final ) you can use the marlinDEV branch
