Function And Common Failure Causes
The ABS pump modulates brake pressure during emergency braking to prevent wheel lock and to support ABS/ESP systems. Failures commonly result from electrical faults, damaged wiring harnesses, internal motor wear, hydraulic contamination or corrosion. Typical symptoms include the ABS warning lamp illuminated, intermittent ABS operation, unusual pump noise or degraded braking feel.
Replacement And Installation
Typical replacement steps: disconnect the vehicle battery, secure the vehicle, relieve system pressure, disconnect electrical connectors and brake lines from the ABS unit, remove mounting fasteners and extract the assembly. Install the new unit, reconnect wiring and brake lines, torque fittings to manufacturer specifications and perform a complete bleed of the brake system. A diagnostic tool may be required to clear stored faults and to perform ABS/ESP relearn or system initialization after fitting.
