Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the vehicle's 12V battery to avoid any electrical issues.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, brake cleaner
Remove the wheel covers and tires to access the wheel speed sensors.
Clean the sensors gently with a brush and brake cleaner to remove dirt and debris.
Inspect wiring and connectors for damage or corrosion; repair as necessary.

3. Check and Replace Brake Fluid

Tools Required: Brake fluid, funnel, turkey baster
Use a turkey baster to remove old brake fluid from the reservoir.
Refill with the recommended brake fluid type as specified in the owner's manual.
Bleed the brake lines if necessary to ensure there are no air pockets.

4. Test and Replace Steering Angle Sensor

Tools Required: Multimeter, replacement steering angle sensor (if faulty)
Locate the steering angle sensor, typically near the steering column.
Use a multimeter to test the output voltage and compare it to the manufacturer’s specifications.
If the sensor is faulty, disconnect it from the harness and remove it using appropriate tools.
Install the new steering angle sensor and reconnect the harness.

5. Reconnect Battery and Clear Codes

Reconnect the 12V battery and ensure all connections are secure.
Use the OBD-II scanner to clear any stored DTCs.
Start the vehicle and check if the traction control light remains off.
