Fuse 16 is the main Terminal 15 fuse for the ABS control unit. If the fuse continues to blow you possibly have a damaged ABS control unit or Valve unit. If the fuse only blew once then this was caused by internal protective devices.

A control unit ususally has a Zener diode and a regular diode in reverse direction present between the supply voltage and GND. The regular diode acts as a crowbar becomes conductive when you reverse polarity of the supply. The Zener diode becomes conductive in an overvoltage situation. Both are to protect the sensitive electronic components. Depending on how long the condition was applied either one of the diodes can fuse and become a conductor.

So if the fuse continues to blow when you replace it one has to assume the ABS control unit is damaged. If it only blew once during the event the protection worked as designed. Replace the fuse, reset the fault codes and be happy.
