-- Place control module without canting it onto hydraulic unit.

Sealing rings are then brought into their end position.

-- Install the hydraulic unit and control module with the new inner Torx bolts diagonally according to the tightening specification.

NOTE:

A new control module may be installed a max. of two times to a used hydraulic unit, to ensure that the elastic gasket seals sufficiently.

A control module which was once in driving operation must not be installed a second time.
