Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Test Wheel Speed Sensors

Tools Required: Multimeter, socket set.
Remove the wheel on which the wheel speed sensor needs inspection.
Locate the wheel speed sensor and disconnect the electrical connector.
Use the multimeter to test the sensor's resistance; it should fall within the manufacturer's specifications.
If the sensor is faulty, replace it with a new one.

3. Check Traction Control Module

Tools Required: OBD-II scanner, screwdriver set.
Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use the OBD-II scanner to check for codes related to the traction control module.
If codes indicate a module fault, access the module under the dashboard and inspect for loose connections or corrosion.
If the module is faulty, replace it following manufacturer guidelines.

4. Brake Fluid and System Inspection

Tools Required: Brake fluid tester, socket set.
Check the brake fluid reservoir for low fluid levels; top off if necessary with the recommended brake fluid type.
Inspect brake lines and components for leaks or damage.
If any leaks are found, replace the damaged components.

5. Tire Inspection

Tools Required: Tire pressure gauge.
Check tire pressure on all four tires and inflate them to the manufacturer’s recommended levels.
Inspect the tires for uneven wear or damage; replace tires if necessary.
