Before starting work, read out fault memory of ABS/ASC+T control module and print out diagnostic record.
Remove and install ABS/ASC+T unit.
To remove the ABS/ASC+T unit, seal the line connections with the plugs provided in the repair kit. This prevents brake fluid from being discharged from the hydraulic unit, which in turn makes it easier to bleed the brake system later.
Release screws (1) and carefully detach control module (2) from hydraulic unit (3).
Installation:
Replace micro-encapsulated screws.
