The former Germany captain and coach has been banned from all soccer activities for 90 days.
The 68-year-old's suspension comes after he refused repeated requests for assistance from Michael Garcia, the former U.S. attorney who has led a two-year probe into corruption allegations on FIFA's behalf.
The particular offense is thought to relate to questions regarding the Qatar 2022 World Cup bid, with Beckenbauer having reportedly claimed that Garcia had "no power whatsoever" to demand his cooperation.

The Ethics Committee's deputy chairman Alan Sullivan issued the ban, stating that Beckenbauer has thus far been temporarily suspended since a decision on the main issue cannot be taken early enough.
The case has now been passed on for formal investigation proceedings, with Vanessa Allard, the Ethics Committee's investigatory chamber member heading the panel that will decide whether Beckenbauer is open to further punishment.
Beckenbauer, who played 103 times for West Germany, won the 1972 European Championship and 1974 World Cup as a player before going on to coach his national side to the 1990 World Cup title.
