Solution

1. Preparation

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

2. Inspect and Replace ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine bay).
Remove the cover and locate the ABS fuse.
Use a fuse puller or pliers to remove the fuse and check for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Check Brake Fluid Levels

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the recommended brake fluid type (typically DOT 3 or DOT 4).

4. Clean or Replace ABS Sensors

Raise the vehicle using jack stands and remove the wheels for better access.
Locate the ABS sensors on each wheel hub.
Clean the sensors and the area around them using brake cleaner.
If damaged, remove the sensor from the hub (usually held by one or two screws) and replace it with a new one.

5. Inspect and Repair Wiring

Visually inspect the wiring harness connected to the ABS control module and wheel speed sensors for signs of fraying or damage.
If any damage is found, repair or replace the affected wiring.

6. Reconnect Battery and Reset ABS Light

Reconnect the negative terminal of the battery.
Use an OBD-II scanner to clear any ABS trouble codes and reset the ABS light.
