Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any dirt or debris surrounding the sensors using a soft brush.
If necessary, disconnect the sensor connectors to inspect for corrosion or damage.
Reconnect the sensors after cleaning and ensure they are securely attached.

3. Replace Faulty ABS Fuse

Locate the fuse box (refer to the owner's manual for the exact location).
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Replace it with a new fuse of the same amperage rating.

4. Brake Fluid Check and Replacement

Remove the master cylinder cap and check the brake fluid level.
If low, top up with the recommended brake fluid (usually DOT 3 or DOT 4).
If the fluid is contaminated or discolored, perform a brake fluid flush.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and check if the ABS light is still illuminated.
Perform a test drive to verify the ABS system is functioning correctly.
