Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the battery to prevent electrical shorts.

2. Scan and Clear Codes

Use an OBD-II scanner to read any ABS-related codes.
Document the codes before clearing them.
Clear the codes and check if the ABS light returns after a short drive.

3. Inspect Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove the sensor connector and inspect for any dirt or damage.
Clean the sensors with an appropriate cleaner if necessary, or replace if damaged.

4. Check ABS Module and Connections

Locate the ABS module and inspect the wiring harness for any signs of wear or corrosion.
Ensure all connections are secure.
If any issues are found, repair or replace the affected components.

5. Brake Fluid Inspection

Remove the brake fluid reservoir cap and check the fluid level.
If low, top up with the manufacturer-recommended brake fluid type (DOT 3 or DOT 4).
If the fluid appears contaminated, perform a brake fluid flush.

6. Fuses Check

Locate the fuse box and identify the ABS fuses.
Remove the fuses and inspect for any blown fuses.
Replace any blown fuses with the correct amperage rating.
