Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure the ignition is off.
Disconnect the negative terminal of the battery for safety.

2. Inspect Wheel Speed Sensors

Remove the wheel for better access to the sensor.
Inspect the wheel speed sensor wiring for any visible damage or corrosion.
Clean the sensor and connector with electrical cleaner if dirty.
Reinstall the wheel and ensure it is torqued to the manufacturer's specifications.

3. Check Brake Fluid and System

Inspect the brake fluid reservoir for proper fluid level.
If low, top off with the manufacturer-recommended brake fluid.
Inspect brake lines and connections for leaks or wear.
If leaks are found, replace the affected components.

4. Verify Tire Pressure

Use a tire pressure gauge to check the inflation of each tire.
Inflate or deflate tires to the recommended pressure as specified by the manufacturer.
Ensure all tires have even tread wear and are in good condition.

5. Clear Error Codes

Reconnect the negative terminal of the battery.
Use the OBD-II scanner to clear any stored error codes.
Start the vehicle and check if the stability control light remains off.
