Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Check ABS Fuses

Locate the fuse box in the engine compartment and identify the ABS fuse.
Remove the ABS fuse using a fuse puller.
Inspect the fuse for continuity; replace it if blown.
Reinstall the fuse and reconnect the battery.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector of each sensor.
Clean the sensor and the surrounding area to remove dirt and debris.
Reconnect the sensors and ensure they are securely fastened to the hub.

4. Test ABS Pump

Reconnect the battery and use a multimeter to check the voltage at the ABS pump connector while depressing the brake pedal.
If no voltage is detected, trace wiring back to the ABS control module for issues.
If voltage is present but the pump does not activate, replace the ABS pump.

5. Inspect Brake Fluid and Leaks

Check the brake fluid reservoir for proper fluid levels.
Inspect brake lines and the ABS module for any signs of leaks.
If fluid is low, identify and repair any leaks, then refill the brake fluid with the manufacturer-recommended type.
