Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and a cleaning brush.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery before starting work to prevent electrical shorts.

2. Addressing Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any error codes related to the stability control system.
Based on the codes, focus on the relevant components (e.g., wheel speed sensors, ABS module).

3. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt using a cleaning brush.
If damaged, replace the affected sensor with a new one.
Reconnect the wiring securely.

4. Check and Repair ABS Module

Inspect the ABS module for signs of electrical issues or leaks.
Use a multimeter to test the wiring harness for continuity.
Repair or replace any damaged wires or connectors.
If the ABS module is faulty, replace it according to manufacturer specifications.

5. Verify Steering Angle Sensor

Use a scan tool to check the steering angle sensor calibration.
If the sensor is out of range, follow the vehicle-specific procedure to recalibrate it.

6. Tire Condition and Pressure Check

Measure tire pressure using a tire gauge and inflate to the manufacturer-recommended levels.
Inspect tires for uneven wear or damage. Replace if necessary.

7. Reconnect Battery and Test

Reconnect the battery terminals securely.
Clear the error codes using the OBD-II scanner.
Start the vehicle and check if the stability control light remains off.
