The brake bleeding function is only necessary if it is suspected that air has entered the ABS-system's hydraulic unit, or in case of reduced brake function when the ABS-system has activated the ABS-function.
Note:
Check all hydraulic connections and couplings if the ABS hydraulic unit has been replaced.
Make sure that the battery is charged. Low battery voltage may impact the brake bleeding process.
Test conditions:
Battery voltage above 11.5 V.
Ignition on, engine off.
