Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery negative terminal to ensure safety during repairs.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt around the sensors.
Check the wiring harness for any signs of damage or disconnection.
Clean the sensor using an electrical cleaner if necessary.

3. Check Brake Fluid Level

Locate the brake fluid reservoir.
Inspect the fluid level; if low, top it up with the manufacturer's recommended brake fluid.
Check for any leaks in the brake lines or near the master cylinder.

4. Inspect ABS Control Module

Locate the ABS control module.
Visually inspect for corrosion, loose connections, or damaged wiring.
If corrosion is found, clean the terminals using electrical contact cleaner.

5. Test Drive and Reset System

Reconnect the battery terminal.
Start the vehicle and check if the ABS light has turned off.
Perform a test drive to ensure that the ABS and traction control systems are functioning properly.
If the light remains on, further diagnostics may be needed, potentially requiring a professional scan tool.
