Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical issues during repairs.
Allow the vehicle to cool down if the brakes have been recently used.

2. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensor area.
Disconnect the wiring harness from each sensor and check for continuity using a multimeter.
Replace any damaged sensors with new ones.

3. Check ABS Module and Wiring

Inspect the ABS module for any visible damage.
Examine the wiring harness for frayed wires or loose connections.
Clean any corrosion on connectors using electrical contact cleaner.
Reconnect any loose connections and ensure a secure fit.

4. Inspect Brake Fluid Level

Open the master cylinder reservoir cap.
Check the brake fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the appropriate brake fluid type (DOT 3 or DOT 4, as specified in the owner's manual).
Replace the cap securely after checking.

5. Test Brake System

Reconnect the battery and ensure all tools are removed from the engine bay.
Start the vehicle and check if the ABS light is still illuminated.
Perform a test drive to evaluate brake performance and check if the traction control system is functional.
