Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Use a socket set to remove the wheel(s) for access.
Locate the wheel speed sensors and check for dirt or debris.
Clean sensors using brake cleaner and a soft cloth.
Reconnect any disconnected wiring and secure with zip ties if necessary.

3. Check ABS Module and Wiring

Locate the ABS module under the hood.
Inspect wiring harness for frays, corrosion, or loose connections.
If necessary, use a multimeter to test continuity in wiring.
Replace any damaged wiring or connectors.

4. Brake Fluid Level Check

Open the hood and locate the brake fluid reservoir.
Check the fluid level; top up with appropriate brake fluid (DOT 3 or DOT 4 as specified).
Inspect for leaks in brake lines and connections.
