Solution

1. Preparation

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

2. Inspect and Replace Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove the fasteners securing the sensors using a socket set.
Disconnect the electrical connector from each sensor.
Inspect the sensors for dirt or damage; clean if necessary.
If damaged, replace with new sensors:
- Align the new sensor in position.
- Secure with fasteners and reconnect the electrical connector.

3. Check ABS Module and Wiring

Inspect the ABS module for any visible damage or corrosion.
Check wiring harnesses for frays or disconnections.
If necessary, replace the ABS module based on the manufacturer’s specifications.

4. Brake Fluid and System Inspection

Check the brake fluid reservoir; ensure it is at the recommended level.
Inspect brake lines and hoses for leaks or damage.
If leaks are found, replace the damaged components and refill the brake fluid.

5. Traction Control Switch Testing

Locate the traction control switch on the dashboard.
Remove the switch from its housing.
Use a multimeter to test the switch for continuity; replace if defective.
