Solution

1. Preparation

Gather tools and parts for inspection and repair.
Ensure the vehicle is on a flat surface, and set the parking brake.
Wear safety goggles and gloves for protection.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Record any error codes that are related to the ABS system.

3. Inspect the ABS Components

ABS Fuse:
- Locate the fuse box and find the ABS fuse.
- Remove the fuse and check for continuity using a multimeter. Replace if blown.
Wheel Speed Sensors:
- Raise and secure the vehicle on jack stands.
- Locate each wheel speed sensor (typically mounted near the wheel hub).
- Clean any dirt or debris around the sensors and check the wiring for damage.

4. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; top up with the manufacturer-recommended brake fluid if low.
Check the fluid condition; if it's dark or contaminated, perform a brake fluid flush.

5. Inspect Wiring and Connectors

Trace the wiring from the ABS module to each wheel speed sensor.
Look for frayed wires, loose connections, or corrosion.
Repair or replace any damaged wiring or connectors.

6. Reset ABS System

After repairs, clear any error codes using the OBD-II scanner.
Turn the ignition off and then back on to check if the ABS light remains off.
