Solution

1. Preparation

Gather necessary tools and parts as listed below.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect and Clean ABS Wheel Speed Sensors

Locate each wheel speed sensor (typically near the brake calipers).
Remove any dirt or debris from the sensor and mounting area using a clean cloth.
Check the sensor for physical damage; replace if necessary.

3. Check and Replace ABS Fuse

Locate the fuse box (refer to the owner's manual for the specific location).
Remove the ABS fuse and inspect it for continuity; replace if it is blown (use the same amperage as specified).
Reinstall the fuse and ensure it is securely in place.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness for any frayed or damaged wires.
Ensure all connectors are secure and free of corrosion; clean with electrical contact cleaner if necessary.

5. Brake Fluid Check and Replacement

Remove the brake fluid reservoir cap and check the fluid level; top off with manufacturer-recommended brake fluid if low.
If the brake fluid is contaminated (dark or cloudy), perform a complete brake fluid flush.

6. Test ABS Pump and Module

Reconnect the battery terminal.
Use a scan tool to perform an ABS pump activation test; listen for the pump operation.
If the pump does not activate, further diagnosis of the ABS module may be required, which may involve replacement.
