Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Inspect Wheel Speed Sensors

Remove the wheel covers and tires to access the wheel speed sensors.
Clean the sensors with a brake cleaner to remove dirt and debris.
Check the wiring harness for frays or disconnections.
Reassemble the wheel and tire.

3. Check Brake Fluid Level

Locate the brake fluid reservoir.
Remove the cap and inspect fluid level. If low, add manufacturer-recommended brake fluid.
If the fluid is contaminated, perform a brake fluid flush and replace with new fluid.

4. Test Traction Control Switch

Reconnect the battery terminal.
Start the vehicle and press the traction control switch.
Observe the dashboard for any changes in the traction control light status. If the light remains on, the switch may need replacement.

5. Inspect ABS Module

Locate the ABS module in the engine compartment.
Check for any visible damage or worn connectors.
If necessary, replace the ABS module or repair the wiring as indicated by diagnostic codes.
