Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Remove the wheel corresponding to the sensor you are inspecting.
Use a socket set to remove the sensor mounting bolt.
Disconnect the wiring harness from the sensor.
Inspect the sensor for dirt or damage; clean or replace if necessary.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Remove the cap and check the fluid level; add DOT 4 brake fluid if low.
Inspect the fluid for contamination; replace if dirty.

4. Inspect ABS Module

Locate the ABS module, usually found near the master cylinder.
Visually inspect for any leaks or electrical connector issues.
If necessary, use a multimeter to test the ABS module for proper operation.

5. Tire Condition Inspection

Check all tires for proper tread depth; replace any tires with tread below 2/32".
Inspect tire pressure with a gauge and inflate to manufacturer specifications.

6. Test Traction Control Switch

Locate the traction control switch, typically on the dashboard.
Use a multimeter to test for continuity when the button is pressed.
Replace the switch if it does not function correctly.
