Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety during repairs.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Torque wrench
Cleaning supplies (for sensors)

2. Inspect Wheel Speed Sensors

Locate and remove the wheel speed sensors at each wheel hub.
Clean the sensor connectors and mounting surfaces using electrical cleaner.
Reinstall the sensors and ensure they are secured properly.

3. Check Brake Fluid Level

Open the brake fluid reservoir cap.
Inspect the fluid level; if low, top up with the manufacturer-recommended brake fluid.
Check for any leaks in the brake lines and connections, repairing as necessary.

4. Calibrate Steering Angle Sensor

Use the OBD-II scanner to access the steering angle sensor settings.
Follow the scanner prompts to recalibrate the sensor according to manufacturer specifications.

5. Inspect ESC Control Module

Locate the ESC control module, usually found near the central control unit.
Ensure all wiring harnesses are securely connected and free of corrosion.
If necessary, replace the module using the manufacturer's guidelines.

6. Reconnect Battery and Test

Reconnect the battery terminals ensuring tight connections.
