Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical components.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensors using a clean cloth.
If any sensor is damaged, replace it with a new one.
Ensure the connectors are secure and free from corrosion.

3. Check and Refill Brake Fluid

Locate the brake fluid reservoir.
Remove the cap and check the fluid level; refill with the manufacturer-recommended brake fluid if low.
Inspect for any signs of leaks in the brake lines or around the master cylinder.

4. Inspect ABS Module and Wiring

Locate the ABS module, usually found near the master cylinder.
Visually inspect the wiring harness for any signs of damage or corrosion.
Use a multimeter to test the continuity of the wires leading to the ABS module.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Verify that the switch is functioning correctly by toggling it on and off.
If faulty, replace the switch to restore proper functionality.
