Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to avoid electrical shocks.
Ensure the vehicle is on a flat surface and secured with jack stands if lifting is necessary.

2. Scan for Codes

Connect an OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the ON position without starting the engine.
Record any ABS-related error codes and clear them if necessary. Re-check to see if they return.

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 it is blown.

B. Wheel Speed Sensors

Remove the wheel and inspect the sensor for dirt or damage.
Clean the sensor and connector with electrical contact cleaner.
Replace the sensor if damaged or if cleaning does not resolve the issue.

C. Brake Fluid

Check the brake fluid reservoir for proper level.
If low, top off with the manufacturer-recommended brake fluid.
If contaminated, perform a brake fluid flush and replace with new fluid.

4. Reconnect Battery

Reconnect the negative terminal of the battery securely.
Ensure that all tools are removed from the work area.

5. Test Drive

Conduct a test drive to confirm that the ABS light has extinguished and that the system is functioning properly.
