Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical issues.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Disconnect the electrical connector from each sensor.
Remove the sensor using a suitable socket or wrench (usually 10mm).
Clean the sensor and mounting area with brake cleaner to remove debris.
Reinstall the sensor and reconnect the electrical connector.

3. Check and Replace Brake Fluid

Locate the brake fluid reservoir under the hood.
Inspect the fluid level; if it’s low, top it off with the recommended brake fluid type (typically DOT 4).
If the fluid is contaminated or discolored, perform a brake fluid flush.
Bleed the brake system to remove air and ensure proper fluid level.

4. Inspect ABS Module and Wiring

Locate the ABS module, usually near the master cylinder.
Visually inspect the wiring harness for any signs of wear or damage.
If any issues are found, repair or replace the wiring as necessary.
Ensure all connections are secure.

5. Test the Traction Control Switch

Locate the traction control switch on the dashboard.
With the ignition on, press the traction control switch and monitor the dashboard for any change.
If the light remains on, consider replacing the switch.
