Abs Control Module, Attaching To Abs Hydraulic Unit: Notes

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.

-- 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.

If a new ABS Control Module -J104- was installed, a basic setting on the Steering Angle Sensor -G85-, the Transverse Acceleration Sensor -G200- and the Brake Pressure Sensor 1 -G201- must be performed.

Use the Vehicle Diagnostic Tester.
