Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with jack stands if lifting is required.
Disconnect the battery to prevent electrical shorts.

2. Scan for Fault Codes

Use an OBD-II scanner to check for ABS-related fault codes.
Document any codes found for reference during troubleshooting.

3. Inspect Components

A. ABS Fuse

Locate the fuse box and identify the ABS fuse.
Remove the fuse and inspect for continuity using a multimeter.
Replace with a new fuse if damaged.

B. Wiring and Connectors

Visually inspect the wiring harness leading to the ABS module.
Check for frayed wires, corrosion, or loose connections.
Repair or replace damaged wiring as necessary.

C. Wheel Speed Sensors

Locate the ABS wheel speed sensors on each wheel.
Clean any debris or dirt from the sensors and check for physical damage.
If damaged, replace the wheel speed sensor with a new one.

4. Brake Fluid Inspection

Check the brake fluid level in the master cylinder reservoir.
Top-up with the recommended brake fluid (usually DOT 4).
Inspect for any leaks in the brake lines or connections.

5. Test ABS Module

Reconnect the battery and use the OBD-II scanner to clear any fault codes.
Perform a functional test of the ABS system while driving at low speeds to ensure proper operation.
