Solution

1. Preparation

Gather tools and ensure the vehicle is on a level surface.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensors and connectors.
Use a multimeter to check sensor resistance; it should generally be within manufacturer specifications.
Replace any faulty wheel speed sensors.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if low, top off with the manufacturer-recommended brake fluid.
If the fluid is contaminated, perform a brake fluid flush.

4. Inspect ABS Module and Wiring

Remove any covers or panels obstructing access to the ABS module.
Visually inspect the module and wiring for signs of damage or corrosion.
Repair or replace any damaged wiring or connectors.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is activated.
Replace the switch if it does not function correctly.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored trouble codes.
Start the vehicle and check if the traction control light remains off.
