Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (socket set, screwdrivers), brake fluid.
Disconnect the vehicle battery to prevent electrical shorts.
Allow the vehicle to cool down before starting work on the braking system.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensors and sensor rings using a soft cloth.
Reconnect the sensors ensuring they are securely attached.

3. Check and Replace ABS Fuse

Locate the fuse box and identify the ABS fuse using the vehicle’s manual.
Use a multimeter to test the fuse for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage.

4. Inspect Brake Fluid Level

Open the master cylinder reservoir cap.
Check the brake fluid level; if low, add the appropriate type of brake fluid (usually DOT 3 or DOT 4).
Inspect the fluid for contamination; replace if necessary.

5. Repair or Replace Faulty Components

If diagnostic codes indicate specific faults (e.g., wheel speed sensor failure), replace the affected component.
For damaged wiring or connectors, repair or replace as needed, ensuring secure connections.

6. Reconnect Battery and Clear Codes

Reconnect the vehicle battery.
Use the OBD-II scanner to clear any stored ABS fault codes.
Test drive the vehicle to ensure the ABS light remains off.
