ABS Control Module, Attaching to ABS Hydraulic Unit

ABS Control Module, Attaching to ABS Hydraulic Unit

Assembly is performed in the reverse order of removal. Note the following:

• A new ABS control module (J104) can be installed on an old ABS hydraulic unit (N55) twice, maximum. This assures the elastic seal will not leak.

• A used ABS control module may not be installed a second time.

Excessive shaking (for example, dropping, impact) can damage the ABS control module. Do not use the ABS control module again if this happens.

• Surface must be cleaned before assembling.

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






- Place the ABS control module on the ABS hydraulic unit without tilting it.

Sealing rings are then brought into their end position.

- Install the ABS hydraulic unit and the ABS control module with the new screws provided diagonally and in steps to the tightening specification.

If a new ABS control module was installed, it must be coded.

Use the vehicle diagnostic tester.
