Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, cleaning brush, safety goggles, gloves.
Allow the vehicle to cool down before working on the brake system.

2. Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Clear any existing error codes related to stability control.
Perform a test drive to see if the codes return.

3. Inspect Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Remove the wheel and inspect the wheel speed sensor for dirt or damage.
Clean the sensor and its connector if necessary.
Reinstall the wheel and lower the vehicle.

4. Check Brake System

Inspect the brake fluid reservoir for adequate fluid levels; top off with manufacturer-recommended fluid if low.
Inspect brake lines for leaks; replace any damaged lines.
Bleed the brake system if air is present.

5. Examine ABS Module and Wiring

Locate the ABS module and visually inspect the wiring and connectors for signs of wear or corrosion.
Use a multimeter to test the integrity of the ABS module connections.
Repair or replace any faulty components as necessary.

6. Test Steering Angle Sensor

Using the OBD-II scanner, navigate to the live data section and check the steering angle readings.
If the readings are erratic or not within manufacturer specifications, recalibrate or replace the steering angle sensor as needed.
