Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors on each wheel hub.
2. Clean any dirt or debris from the sensor area using a soft cloth.
3. Use a multimeter to test the resistance of each sensor, ensuring it is within manufacturer specifications.
4. If a sensor is faulty, mark it for replacement.

3. Check Brake Fluid Level

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the brake fluid level, adding fluid if necessary to meet the required level.
3. Inspect the fluid for contamination; if contaminated, flush the brake system.

4. Examine Traction Control Module

Sub-steps:
1. Locate the traction control module, typically near the ABS module.
2. Visually inspect the module and its wiring harness for any signs of corrosion, fraying, or loose connections.
3. Reconnect any loose connectors and secure all wiring.

5. Perform ABS Function Test

Sub-steps:
1. Reconnect the battery and start the engine.
2. Drive the vehicle in a safe area where it can be tested for ABS activation.
3. Test the braking system lightly to ensure the ABS activates correctly without issues.
