Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and ensure the engine is off.
• Disconnect the battery to avoid electrical shorts.

2. Inspect Wheel Speed Sensors

• Locate each wheel speed sensor at the wheel hub.
• Remove any protective covers or brackets.
• Disconnect the electrical connector from each sensor.
• Clean the sensor and the area around it to ensure accurate readings.
• Reconnect the sensors and secure them in place.

3. Check ABS System

• Inspect the ABS module for any visible damage or corrosion.
• Use a multimeter to test the ABS wheel speed sensors for proper voltage.
• If an error code indicates a fault, replace the ABS module as needed.

4. Examine Tire Condition

• Inspect all tires for uneven wear, damage, or low tread depth.
• Verify tire pressure with a tire pressure gauge, ensuring all tires are inflated to the manufacturer's specifications.
• Replace any worn or damaged tires.

5. Test Traction Control Switch

• Locate the traction control switch on the dashboard.
• Disconnect the switch and use a multimeter to check for continuity.
• If defective, replace the switch with a new one.
