Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the 12V battery to prevent electrical issues during testing.

2. Inspect Tires

Tools Required: Tire pressure gauge, tread depth gauge.
Check tire pressure; inflate to recommended PSI if low.
Measure tread depth; replace tires if tread is below 2/32 inches.
Inspect for uneven wear patterns; rotate or align tires if needed.

3. Check Wheel Speed Sensors

Tools Required: Multimeter.
Locate wheel speed sensors on each wheel hub.
Disconnect the sensor connector and test the sensor with a multimeter for continuity.
Clean any debris or dirt around the sensor and connector; replace if faulty.

4. Inspect Suspension and Steering Components

Tools Required: Socket set, pry bar.
Jack up the vehicle and remove the front wheels.
Visually inspect control arms, bushings, and tie rods for wear or damage.
Replace any damaged components and ensure all hardware is torqued to manufacturer specifications.

5. Traction Control System Reset

Tools Required: Diagnostic scanner.
Connect the diagnostic scanner to the OBD-II port.
Clear any error codes related to the traction control system.
Perform a system reset if necessary.
