Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent any electrical shorts during the repair.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any error codes related to the stability control system.
Clear the codes and perform a test drive to check if the issue persists.

3. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter
Remove the wheel assembly to access the wheel speed sensors.
Disconnect the electrical connector from the sensor.
Remove the sensor from its bracket and inspect for damage.
Replace the sensor if faulty, ensuring it is torqued to manufacturer's specifications.

4. Check ABS Module Connections

Locate the ABS module, typically found near the brake master cylinder.
Visually inspect all connections for corrosion or loose wires.
Clean any corrosion present with an appropriate electrical cleaner.
Reconnect all wiring securely.

5. Steering Angle Sensor Calibration

Tools Required: Diagnostic scanner with steering angle calibration capability
Connect the diagnostic scanner and navigate to the ABS/ESC module.
Follow on-screen instructions to calibrate the steering angle sensor.
Confirm calibration is successful and no warning lights remain active.
