Solution

1. Preparation

Gather necessary tools and parts.
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 Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the sensor harness connector by pressing the release tab.
Clean any debris from the sensor and mount area.
Reconnect the sensor and ensure the connection is secure.

3. Check Brake Fluid and System

Inspect the brake fluid reservoir for proper fluid level; top off with manufacturer-recommended brake fluid if low.
Look for any visible leaks in brake lines and connections; repair as necessary.

4. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity in the switch.
If faulty, replace with a new switch and reconnect.

5. Tire Inspection

Check all tires for proper inflation (refer to the vehicle's placard for specific PSI).
Inspect tire tread depth; replace any tires that are worn beyond safe limits.
