Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather tools and parts required for the repair.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve any stored ABS codes and document them.
Clear the codes from the system and check if the ABS light reappears after a test drive.

3. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove the sensor connectors and inspect for corrosion or damage.
Clean the sensor mounting area and reattach the sensors securely.
If sensors are damaged, replace with OEM parts.

4. Check ABS Control Module

Locate the ABS control module, usually found near the master cylinder or under the vehicle.
Inspect the module for any signs of physical damage or corrosion.
If necessary, test the module using a multimeter to ensure it is functioning properly.
Replace the ABS control module if it is faulty.

5. Brake Fluid Inspection

Check the brake fluid reservoir for proper fluid level and condition.
If the fluid is contaminated or low, perform a brake fluid flush and replace it with the manufacturer-recommended fluid.
Reassemble and secure the reservoir cap.
