Solution

1. Preparation

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

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor bolts using a socket set.
Clean the sensor and its connector with electrical cleaner to remove dirt and debris.
Reinstall the sensors and tighten the bolts to the manufacturer’s specified torque (usually around 7-10 ft-lbs or as specified in the service manual).

3. Check and Top Off Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, add the appropriate DOT fluid as specified in the vehicle's manual.
Check for leaks in brake lines or at the master cylinder.

4. Inspect ABS Module

Locate the ABS module, usually found near the brake master cylinder.
Visually inspect for any corrosion or damage.
If damage is found, replace the ABS module.

5. Tire Inspection

Ensure all tires are properly inflated according to the manufacturer's specifications.
Inspect tire tread; if any tires are worn unevenly or below legal limits, replace them.
