Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean ABS Sensors

Tools Required: Socket set, wire brush, cleaning solvent, multimeter.
Locate the ABS wheel speed sensors at each wheel hub.
Remove the sensor retaining bolts and carefully pull the sensors from their mounting.
Clean any dirt or debris from the sensor and the mounting location using a wire brush and cleaning solvent.
Inspect the sensor for damage; replace if necessary.

3. Check and Replace the ABS Fuse

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box, typically found under the dashboard or engine compartment.
Identify the ABS fuse using the fuse diagram on the cover.
Remove the fuse and inspect it for continuity. Replace if blown (use the same amperage).

4. Inspect Brake Fluid Level

Tools Required: None.
Open the master cylinder reservoir cap and check the brake fluid level.
If low, top up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely.

5. Reconnect Battery and Reset ABS System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes and reset the ABS system.
Start the vehicle and check if the ABS light remains off.
