Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set), brake cleaner.
Safety Warnings: Always wear safety goggles and gloves when working on the braking system.

2. Retrieve and Interpret Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve any ABS-related trouble codes and note them for reference.

3. Inspect and Replace ABS Fuse

Locate the fuse box (usually under the dashboard or engine bay).
Identify the ABS fuse as indicated in the owner’s manual.
Use a multimeter to check for continuity; replace the fuse if it is blown.

4. Check Wheel Speed Sensors

Raise the vehicle and secure it on jack stands.
Inspect each wheel speed sensor for damage or disconnection.
Clean any dirt or debris from the sensor area.
If damaged, replace the wheel speed sensor(s).

5. Inspect ABS Module and Pump

Locate the ABS module (usually near the brake master cylinder).
Check for any visible damage or leaks around the module.
Use a scan tool to activate the ABS pump and listen for operation; if it does not activate, consider replacing the ABS pump.

6. Refill Brake Fluid

Check the brake fluid level in the master cylinder reservoir.
If low, refill with the appropriate type of brake fluid (DOT 3 or DOT 4).
Bleed the brake system if air is present.
