Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, brake fluid tester.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery negative terminal to ensure safety during repairs.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor connectors and inspect for corrosion or damage.
Using a multimeter, check the resistance of each sensor. Compare readings to manufacturer specifications (typically 800-1200 ohms).
Clean any dirt or debris around the sensors and reconnect them.

3. Check Tire Condition and Pressure

Inspect all tires for uneven wear, bulges, or damage.
Verify that all tires are inflated to the recommended PSI as per the vehicle's specification.
Replace any tires that are worn or damaged.

4. Inspect Brake Fluid and System

Check the brake fluid reservoir for proper fluid level. Top off with the correct type of brake fluid if low.
Look for leaks in the brake lines and around the ABS module.
If leaks are found, replace the affected components.

5. Reconnect Battery and Clear Codes

Reconnect the battery negative terminal.
Using the OBD-II scanner, clear any stored error codes from the system.
Start the vehicle and observe if the traction control light remains illuminated.
