1. Control module (ABS 5.3 and ABS / TC 5.3)

This unit processes incoming signals and actuates the solenoid valves and/or the return pump in the hydraulic unit when wheel slip is excessive (see also ABS 5.3 SYSTEM DESCRIPTION  and ABS/TC 5.3 SYSTEM DESCRIPTION  ).

If the ABS or ABS/TC switches off when detecting a system fault, it actuates the warning light and stores the fault in a non-volatile memory.

NOTE: Control module and relay are not supplied individually. In the event of replacement, the complete hydraulic unit must be replaced.
