Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Fault Codes

Using the OBD-II scanner, clear the fault codes and check if the stability assist light returns after driving the vehicle.

3. Inspect Wheel Speed Sensors

Remove the wheel on the affected side using a socket set.
Locate the wheel speed sensor and disconnect the electrical connector.
Inspect the sensor for damage or debris; clean or replace as needed.
Reconnect the sensor and reinstall the wheel.

4. Check ABS Module

Locate the ABS module (usually near the brake master cylinder).
Inspect the wiring harness for corrosion or damage.
Ensure all connections are secure; repair or replace as necessary.

5. Verify Brake Fluid Level

Open the hood and locate the brake master cylinder.
Check the brake fluid level; top off with the recommended fluid (DOT 3 or DOT 4) if low.
Inspect for any signs of leaks around the master cylinder and brake lines.

6. Steering Angle Sensor Calibration

If the steering angle sensor is misaligned, recalibrate it using a scan tool that supports this function.
Follow the manufacturer's instructions to perform the calibration procedure.
