A method for checking intended pressure medium-conducting contacting of circuit branches, associated with one another, of separate brake circuits of an electronically slip-controllable power brake system with two actuator units, contacted for conducting pressure medium, for generating and controlling brake pressure, in particular for a motor vehicle, and an electronic control unit for such a power brake system.

Method for checking intended pressure medium-conducting contacting of circuit branches, associated with one another, of separate brake circuits of an electronically slip-controllable power brake system with two actuator units, contacted for conducting pressure medium, for generating and controlling brake pressure, in particular for a motor vehicle

In order to test a function in a pressure generating module of a hydraulic vehicle power brake system, it is provided to generate a brake pressure using a power brake pressure generator and subsequently hydraulically to separate a pressure regulating module from the pressure generating module by closing connection valves or hydraulically to separate wheel brakes from the pressure generating module by closing inlet valves, so that no brake fluid flows into the wheel brakes during the function test, which would reduce the brake pressure in the pressure generating module and negatively affect or prevent the function test.
