Solution

1. Preparation

Gather tools and materials.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the vehicle is on a flat surface and properly secured with wheel chocks.

2. Check and Replace Fuses

Locate the fuse box and refer to the owner's manual for the specific location of the ABS fuses.
Remove the ABS fuses and inspect them for continuity using a multimeter.
- If blown, replace with a fuse of the same amperage.

3. Inspect and Clean Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Locate the ABS wheel speed sensors on each wheel hub.
Disconnect the sensor connectors and inspect for corrosion or debris.
Clean the sensor tips with brake cleaner and a soft cloth.
Reconnect the sensors securely.

4. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Check the brake fluid level; it should be between the minimum and maximum marks.
- If low, add the recommended brake fluid type (usually DOT 3 or DOT 4).
- Inspect for any visible leaks in the lines or around the master cylinder.

5. Test ABS Module

Reconnect the battery.
Use an OBD-II scanner to clear any stored ABS codes.
Perform a test drive to monitor if the ABS light returns.
- If the light reappears, further diagnosis of the ABS module may be required.
