• Disconnect the vehicle battery to ensure safety while working on electrical systems.

2. Inspect Wheel Speed Sensors

• Tools Required: Multimeter, socket set
• Locate the wheel speed sensors at each wheel hub.
• Visually inspect each sensor for physical damage or disconnection.
• Use a multimeter to check for operational voltage at the sensors when the vehicle is in motion; replace if faulty.

3. Check ABS Module

• Tools Required: OBD-II scanner

• Inspect for any leaks in the brake lines or around the master cylinder.

5. Tire Inspection

• Tools Required: Tire pressure gauge
• Check all tires for proper inflation according to the manufacturer’s specifications.
• Inspect tread depth and wear patterns; replace tires if they are excessively worn or damaged.

6. Test Traction Control Switch
