ABS malfunctions do not affect the brake system and the booster. The conventional brake system remains operative even without ABS. A change in braking behavior should be checked. When the ABS indicator lamp comes on, the rear wheels can lock up early when braking.
WARNING:
- The ABS is generally maintenance-free.
- Testing, assembly, and repair work may only be performed by qualified personnel.
- By not observing the points described in the repair manual, the system can be damaged and vehicle safety could be compromised.
The brake system is divided by axle.
- Right and left front.
- Right and left rear.
The brake booster operates pneumatically via the vacuum brake booster.
Sources of malfunctions are reduced by direct connection of components named. The components are replaced instead of repaired.
- Before servicing the ABS, determine the cause of the damage using OBD.
- When installing a new hydraulic control unit, the coding must be checked using the Vehicle Diagnostic Tester.
- Disconnect the battery ground cable when the ignition is switched off.
- When handling brake fluid, observe the applicable safety precautions and information.
- Bleed the brake system using the :VAS6860 for all work that requires opening the hydraulic system. High and low pressure testing should also be performed on the brake system.
- During the final road test, ensure that ABS-controlled braking is performed at least once (pulsation must be felt at the brake pedal). Use the Vehicle Diagnostic Tester.
