Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Remove the wheel and tire assembly to access the brake components.
2. Locate the wheel speed sensors on each wheel hub.
3. Check the wiring and connectors for damage or corrosion.
4. Use a multimeter to test the sensor resistance; it should typically be within the manufacturer’s specified range.
5. Clean any dirt or debris from the sensors and connectors.

3. Check Brake Pedal Switch

Sub-steps:
1. Locate the brake pedal switch, usually mounted above the brake pedal.
2. Inspect the switch for proper alignment and operation.
3. Test the switch with a multimeter to ensure it opens and closes correctly.

4. Inspect ABS Module

Sub-steps:
1. Locate the ABS module; typically found near the master cylinder.
2. Check for any visible damage or leaks.
3. Inspect wiring and connectors for signs of wear or corrosion.
4. If necessary, perform a bench test of the ABS module using manufacturer specifications.

5. Replace Faulty Components

Sub-steps:
1. If any wheel speed sensor is faulty, replace it with a new part, tightening to the manufacturer’s torque specifications.
2. If the brake pedal switch or ABS module is defective, replace as needed, ensuring a proper connection.
