New Control Module, Installing


Excessive shaking (for example dropping, impact) may destroy the control module. Control module must then no longer be used.

Surface must be cleaned before assembling.

- Slide all sealing rings - A - slightly over the valve dome.






- Place control module without canting it onto hydraulic unit.

Sealing rings are then brought into their end position.

- Bolt hydraulic unit and control module with new inner Torx(R) bolts supplied.

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.

Do not install a used control module.
