Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Retrieve Trouble Codes

Connect the OBD-II scanner to the vehicle’s OBD-II port.
Turn the ignition to the "ON" position but do not start the engine.
Follow the scanner's instructions to retrieve any ABS-related trouble codes.
Document the codes for reference in troubleshooting.

3. Inspect Fuses

Locate the fuse box; refer to the owner's manual for the specific location.
Use a fuse puller to remove the ABS fuse.
Visually inspect the fuse for continuity; replace it if it is blown.

4. Check Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Locate each wheel speed sensor on the brake assembly.
Inspect the sensor wiring for frays or disconnections.
Clean any dirt or debris from the sensor area with a soft cloth.

5. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the appropriate brake fluid as specified in the owner's manual.

6. Test ABS Module and Pump

Reconnect the battery terminal.
Turn the ignition to the "ON" position without starting the engine.
Use a multimeter to test the ABS pump and module according to the manufacturer’s specifications.
Replace any faulty components as necessary.
