The only time the service brake bleed function is required, is when it is suspected that air has entered the ABS hydraulic
unit, or inferior braking performance is experienced while the ABS unit has activated the ABS function.
Note:
Check all the hydraulic connections and fittings if the ABS hydraulic unit has been replaced.
Make sure the battery has a sufficient charge. Low battery can affect the brake bleed process.
Test prerequisite:
The battery voltage should be above 11.5V.
Ignition on, engine off.
Procedure:
Choose the basic setting: Bleed the brake system. The bleeding sequence has now been activated and the following check steps and prompts will be displayed:
Open brake bleed nipple and attach a fluid container
Service bleed operation is in progress.
Continue to bleed the brakes until there are no air bubbles visible.
Ensure that the bleeding nipple is closed before you stop the bleeding cycle.
Press ok when done.
Press abort if you want to quit.
This process is same for each wheel in the brake bleed function.
