Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the negative battery terminal to avoid electrical shorts.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Screwdriver set
Brake fluid (if necessary)

2. Check ABS Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the cover and locate the ABS fuse.
Use a multimeter to check for continuity; replace the fuse if it is blown.

3. Inspect Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensor.
Visually inspect the sensor for damage or dirt.
Clean the sensor with brake cleaner if dirty; replace if damaged.

4. Inspect Wiring and Connectors

Trace the wiring from the wheel speed sensor to the ABS module.
Check for fraying, corrosion, or disconnections.
Repair or replace any damaged wiring or connectors.

5. Test ABS Pump and Module

Reconnect the battery terminal.
Use an OBD-II scanner to run a diagnostic test on the ABS system.
If the pump or module is faulty, replace the ABS module according to manufacturer specifications.

6. Verify Brake Fluid Level

Check the brake fluid reservoir for adequate fluid levels.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect for any leaks in the brake lines.
