Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather tools and parts: OBD-II scanner, multimeter, socket set, wheel chocks, and safety gloves.

2. Read and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the ON position without starting the engine.
Read and note any error codes associated with the ESC system.
Clear the codes and monitor if they return after a test drive.

3. Inspect Wheel Speed Sensors

Jack up the vehicle and remove the wheels to access the wheel speed sensors.
Disconnect the sensor connectors and visually inspect for damage.
Use a multimeter to test for continuity and proper voltage at the sensor terminals.
Replace any faulty sensors.

4. Check Brake Fluid and Leaks

Open the hood and inspect the brake fluid reservoir.
Ensure the fluid is at the proper level; top off with manufacturer-recommended brake fluid if necessary.
Inspect brake lines for wear or leaks, particularly around the ABS module.

5. Inspect ABS Module and Wiring

Locate the ABS control module, typically near the master cylinder.
Check for loose or damaged wiring connections.
Clean any corrosion present on terminals and connectors.

6. Test Steering Angle Sensor

Use the OBD-II scanner to access the steering angle sensor data.
If the sensor is out of range, recalibrate it according to the manufacturer’s specifications.
Follow the specific steps outlined in the service manual for your model.
