ABS Control Module -J104-, ATTACHING TO ABS Hydraulic Unit -N55- (ABS MARK 60 EC ABS/EDL/ASR/ESP): Installation

Assembly is performed in reverse order. Note the following:

NOTE:

A new ABS Control Module -J104- can be installed on an old ABS Hydraulic Unit -N55- maximum twice. This assures the elastic seal will not leak.

A used ABS Control Module -J104- may not be installed a second time.

WARNING: Excessive shaking (for example, dropping, impact) can damage the ABS Control Module -J104-. Do not use the ABS Control Module -J104- again if this happens.

Surface must be cleaned before assembling.

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