Abstract
The disclosure relates to a method for testing a shuttle valve in a pneumatic system, wherein the shuttle valve has a first shuttle valve port, a second shuttle valve port and a third shuttle valve port, wherein the higher of the pressures prevailing at the first shuttle valve port and second shuttle valve port is modulated at the third shuttle valve port in each case, wherein the method includes the steps: a) modulating a first pressure at the first shuttle valve port; b) ascertaining a value, which is indicative of the first pressure, at the first shuttle valve port; and c) comparing the value indicative of the first pressure with a first predetermined comparison value provided for this, and, in the event of a deviation greater than a first tolerance: ascertaining and/or outputting a fault of the shuttle valve.
