Control Module, Separating From Hydraulic Unit
Special tools and workshop equipment required
- ESD Work Surface:VAS6613
- The ABS Hydraulic Unit -N55- with the ABS Control Module -J104- must be removed in order to separate the control module and the hydraulic unit.
- The return flow pump must not be separated from the ABS Hydraulic Unit -N55-.
Procedure
-- Remove the hydraulic control unit. Refer to ABS Control Module -J104- /ABS Hydraulic Unit -N55-, Removing And Installing .
There is a risk of destroying the control module through the electrostatic charge and reduced cleanliness.
- Discharge electrostatic charge: touch the electro-static discharge work surface
- Protect the inner control module from moisture and dirt.
-- Place the hydraulic unit with the control module on the ESD Work Surface:VAS6613 .
- The control module -2- faces upward and the hydraulic unit -4- with the pump motor and connector -3- faces down.
-- Remove the bolts -1- and dispose of them.
-- Carefully remove the control module vertically upward without tilting.
- Blowing the control module or hydraulic unit out with compressed air is not permitted.
- The valve bodies inside the hydraulic unit must not be damaged or bent.
-- Cover the open hydraulic unit with a lint-free cloth.
-- Check the hydraulic unit sealing surface, and if necessary, clean with mineral spirits and a lint-free cloth.
-- A damaged sealing surface must not be mechanically reworked. A hydraulic unit with a damaged sealing surface must be replaced.
Risk of damaging the control module due to improper handling.
- Do not remove or lift the seal.
