Solution

1. Preparation

Gather tools including an OBD-II scanner, socket set, multimeter, and a torque wrench.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors on each wheel hub.
2. Remove any protective covers if necessary using a socket set.
3. Inspect the wiring for frays or breaks.
4. Clean any debris around the sensors using a soft brush.
5. Reconnect any loose connections and ensure they are secure.

3. Check ABS Control Module

Sub-steps:
1. Locate the ABS control module, typically found near the master cylinder.
2. Inspect for any visible signs of damage or corrosion.
3. Reconnect any loose wiring harnesses.
4. Use the OBD-II scanner to clear any error codes and test the system.

4. Brake System Inspection

Sub-steps:
1. Check the brake fluid level in the reservoir; refill if low with the recommended fluid type (DOT 4).
2. Inspect brake lines for signs of leaks or damage.
3. Ensure the brake pads and rotors are in good condition and not worn.

5. Test Traction Control Switch

Sub-steps:
1. Locate the traction control switch on the dashboard.
2. Use a multimeter to test the switch for continuity.
3. If the switch is faulty, replace it with a new part.

6. Battery Check

Sub-steps:
1. Inspect battery terminals for corrosion and clean if necessary.
2. Use a multimeter to check the battery voltage; it should be around 12.6 volts when fully charged.
3. If the battery is weak, consider replacing it.
