Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, set the parking brake, and disconnect the battery.

2. Check and Replace ABS Fuse

Locate the fuse box and find the ABS fuse using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.
Reconnect the battery.

3. Inspect and Replace Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Disconnect the wiring harness from the sensors.
Remove the mounting bolt and take out the sensor.
Install the new wheel speed sensor by reversing the removal steps, ensuring it is securely fastened and connected.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the minimum and maximum markings.
If low, top up with the recommended brake fluid type (DOT 3 or DOT 4).
Close the reservoir cap securely.

5. Perform a System Reset

Reconnect the battery.
Start the vehicle and allow it to idle for a few minutes.
Test drive the vehicle to see if the ABS light has turned off.
