Indicated on display:

The EDL change-over valve (left) and the EDL inlet valve are activated.
ABS return flow pump -V39- runs for one second. It draws brake fluid from
the brake fluid expansion tank via the EDL inlet valve. The hydraulic pump
builds brake fluid pressure in the EDL regulated wheel cylinders. These
wheels will then be locked.
If not, this indicates a mechanical malfunction in one of the valves,
providing there is no electrical malfunction in the system. Replace
hydraulic control unit.
