Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Set the vehicle on a level surface and engage the parking brake.

2. Inspect and Clean Wheel Speed Sensors

Remove the wheel on the affected side using a socket set.
Locate the wheel speed sensor, usually mounted near the brake rotor.
Clean any debris or dirt from the sensor and its mounting area.
Reinstall the wheel and torque to the manufacturer’s specifications.

3. Check and Replace Brake Fluid

Open the brake fluid reservoir cap.
Inspect the fluid for contamination or discoloration.
If contaminated, use a brake bleeder kit to flush the system and replace with new brake fluid (DOT 4).
Recheck the brake fluid level and cap securely.

4. Calibrate Steering Angle Sensor

Reconnect the battery and use a diagnostic tool to access the steering angle sensor settings.
Follow the tool's instructions to recalibrate the sensor.
Clear any existing error codes from the system.

5. Inspect Stability Control Module

Locate the stability control module, typically found under the dashboard or near the driver's side.
Check for loose connections and corrosion on the wiring and connectors.
If damaged, replace the module with an OEM part, following specific installation instructions.
