Solution

1. Preparation

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

2. Scan for Error Codes

Reconnect the battery and turn on the ignition (do not start the engine).
Connect the OBD-II scanner and note any error codes related to the traction control or ABS system.
Clear the codes and see if they return after a short drive.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub assembly.
Disconnect the electrical connector and check for damage or corrosion.
Clean the sensor area with a soft cloth to remove any debris.
Reconnect and secure the sensor.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, fill it with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Check for any visible leaks in the brake lines or around the master cylinder.

5. Inspect ABS Module

Locate the ABS module (usually near the brake master cylinder).
Check for any visible damage, loose connections, or corrosion on the connectors.
If necessary, replace the ABS module as per manufacturer specifications.

6. Test the Traction Control Switch

Locate the traction control switch (often near the gear shift).
Inspect the switch for damage and ensure it is functioning properly.
If the switch is faulty, replace it with a new one.
