Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is turned off.
Gather necessary tools and replacement parts.

2. Clear Error Codes

Use the OBD-II scanner to clear any existing error codes.
Reconnect the scanner to check if the codes reappear after clearing.

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Disconnect the wiring harness from the sensors.
Clean the sensors using an appropriate cleaner and a soft cloth, ensuring no debris is left.
Reconnect the wiring harness securely.

4. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top up with the manufacturer-recommended brake fluid.
Check the condition of the brake fluid; if contaminated, consider a brake fluid flush.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test the continuity of the switch.
If faulty, replace the switch with a new one.

6. Inspect ABS System

Check the ABS module for any visible damage or leaks.
If necessary, use a multimeter to test the ABS pump and module for proper operation.
