Solution

1. Preparation

Gather tools and materials including an OBD-II scanner, multimeter, socket set, and replacement parts as necessary.
Ensure the vehicle is parked on a level surface with the engine off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and record any error codes related to the ABS system.

3. Inspect and Replace Wheel Speed Sensors

Lift the vehicle using a jack and secure with jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector and check for corrosion or damage.
Use a multimeter to test for continuity; replace any faulty sensors with new ones.

4. Check and Replace ABS Fuse

Locate the fuse box and identify the ABS fuse using the diagram on the lid.
Remove the fuse and check for continuity using a multimeter.
Replace the fuse if it is blown with a new fuse of the same amperage.

5. Inspect the ABS Module

Visually inspect the ABS module for any signs of damage or fluid leaks.
If there are leaks, the module may need to be replaced.
Follow manufacturer specifications for replacing the ABS module if necessary.

6. Verify Brake Pedal Switch

Locate the brake pedal switch; it is usually mounted on the brake pedal assembly.
Use a multimeter to test the switch for proper operation.
Replace the switch if it does not function as intended.
