Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Allow the engine to cool before starting work.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor mounting bolts using a socket set.
Carefully pull the sensor out and inspect for dirt or damage.
Clean the sensor and its mounting area with brake cleaner.
Reinstall the sensor and torque bolts to manufacturer specifications.

3. Examine ABS Module and Wiring

Locate the ABS module in the engine compartment.
Check for loose or damaged wiring connected to the ABS module.
Ensure all connectors are secure and free of corrosion.
If any wiring is damaged, repair or replace it as needed.

4. Test and Replace Brake System Components

Check the brake fluid level in the reservoir; refill if low.
Inspect brake pads and rotors for wear.
If any issues are found, replace worn brake components as necessary.

5. Verify Traction Control Switch Functionality

Locate the traction control switch on the dashboard.
Use a multimeter to test the switch for continuity when pressed.
Replace the switch if it fails the continuity test.
