Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
If the fluid level is low, top it off with the recommended brake fluid type (DOT 3 or DOT 4).
Reconnect the battery terminal and start the vehicle to check if the ABS light turns off.

3. Inspect ABS Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Remove the sensor connector and visually inspect for dirt or corrosion.
Clean the sensors with electrical contact cleaner and reconnect them.

4. Test ABS System

Use an OBD-II scanner to clear any stored ABS trouble codes and monitor the system.
Test drive the vehicle to ensure the ABS light does not re-illuminate and that the ABS functions correctly during braking.

5. Replace Faulty Components

If the ABS light remains on, replace any faulty wheel speed sensors or the ABS module as indicated by diagnostic codes.
Follow manufacturer specifications for installation and torque values.
