Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning solvent, soft brush.
Locate the wheel speed sensors at each wheel hub.
Remove the sensor mounting bolts using the socket set.
Carefully pull the sensors from their housing and inspect for damage.
Clean the sensors and their connectors with cleaning solvent and a soft brush.
Reinstall the sensors and secure them with the mounting bolts.

3. Check Brake Fluid Level

Tools Required: Brake fluid (if low).
Locate the brake fluid reservoir under the hood.
Inspect the fluid level against the markings on the reservoir.
If the fluid is low, top it up with the recommended brake fluid type as per the owner's manual.

4. Inspect ABS Module

Tools Required: Multimeter.
Locate the ABS module under the hood.
Inspect the wiring and connectors for signs of wear or corrosion.
Use the multimeter to check for continuity in the ABS wiring.
Repair or replace any damaged wires or connectors.
