Abs Control Module, Attaching To Abs Hydraulic Unit: Notes

WARNING: This page is about a different car, the 2015 Volkswagen Passat, 2014 Volkswagen Passat, 2013 Volkswagen Passat, and 2012 Volkswagen Passat. However, it is still accessible from the selected car via links, so may be relevant.

Assembly is performed in reverse order of removal. Pay attention to the following:

NOTE:

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) may destroy the control module. The 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 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 -J104- was installed, it must be coded.

Use the Vehicle Diagnostic Tester.
