Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and note down the ABS error codes for further diagnosis.

3. Inspect and Replace Components

A. ABS Fuse

Locate the fuse box and identify the ABS fuse.
Remove the fuse and check for continuity using a multimeter.
Replace the fuse if defective and recheck the ABS system.

B. Wheel Speed Sensors

Lift the vehicle and remove the wheels (if necessary) for better access.
Disconnect the connector from each wheel speed sensor.
Clean the sensor and mounting area to remove debris.
If damaged, replace the wheel speed sensor with a new one.

C. ABS Control Module

Inspect the ABS control module connections for corrosion or looseness.
If the module is damaged, replace it by unbolting it from its mount and disconnecting the wiring harness.

4. Clear Error Codes

After repairs, reconnect the OBD-II scanner.
Clear the ABS error codes and reset the system.
Start the vehicle and check if the ABS light remains off.
