- Ideal for mechanics and experienced DIY technicians familiar with brake system procedures.
How It Works
The ABS pump provides hydraulic pressure modulation during anti-lock braking events while the electronic control module monitors wheel speed sensors and controls the pump and solenoid valves. When the system detects wheel lock, the module commands the pump and valves to modulate brake pressure, maintaining steering control under heavy braking.
Common Faults And Lifespan
ABS pumps and control modules can fail due to moisture ingress, corrosion, contaminated brake fluid, electrical faults in the control electronics, or mechanical wear of the pump motor. Symptoms include illuminated ABS warning light, intermittent ABS activation, a pulsating brake pedal at low speeds, unusual pump noise, or reduced ABS function. Lifespan varies with vehicle use and maintenance; failures are more common on higher-mileage cars or vehicles exposed to salty or humid environments.
Replacement And Installation Notes
Replacement should be carried out by a skilled technician or an experienced DIYer with the correct tools. Typical steps:
- Disconnect the negative battery terminal and wait a few minutes to protect the electronic unit.
- Read and record ABS fault codes with a diagnostic tool before removal.
- Protect the work area and prepare to capture brake fluid to prevent contamination.
- Disconnect electrical connectors and remove hydraulic lines from the unit (use correct line wrenches; be prepared to reseal or replace banjo bolts and crush washers if necessary).
- Unbolt and remove the ABS pump/module assembly; install the replacement in reverse order.
- Refill and properly bleed the brake system according to manufacturer procedure to remove air from circuits.
- Clear ABS fault codes and perform a road test and system checks with diagnostic equipment to confirm correct operation.
