Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris around the sensors using a soft cloth.
Check the wiring harness for any signs of fraying or disconnection.
Reconnect any loose connections and ensure they are secure.

3. Check Brake Fluid Level

Open the hood and locate the brake master cylinder reservoir.
Check the fluid level against the minimum and maximum markings.
If the fluid is low, top it up with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect for any signs of leaks in the brake lines or around the master cylinder.

4. Test ABS System

Reconnect the battery and turn on the ignition without starting the engine.
Activate the ABS system by pressing the brake pedal firmly.
Listen for any unusual noises or vibrations to ensure the ABS is functioning correctly.

5. Reset Traction Control Light

Using the OBD-II scanner, clear any stored fault codes.
Start the engine and check if the traction control light turns off.
Take the vehicle for a test drive to verify the repair.
