Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on the electrical system.

2. Check ABS Fuse

Locate the fuse box (refer to the owner's manual for location).
Remove the ABS fuse and check for continuity using a multimeter.
Replace the fuse if it is blown with a new fuse of the same amperage.

3. Inspect Wheel Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the wheel speed sensors.
Inspect each sensor for dirt, damage, or loose connections.
Clean the sensors with brake cleaner and a soft cloth. If damaged, replace the sensor with a new one.

4. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Check the fluid level; it should be between the minimum and maximum marks.
If low, refill with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Inspect brake lines for leaks, replacing any damaged sections as necessary.

5. Test ABS Module

Reconnect the vehicle battery.
Use the OBD-II scanner to clear any existing ABS fault codes.
Start the vehicle and observe if the ABS light turns off after a few seconds.
If the ABS light remains on, further testing of the ABS module may be needed, including checking wiring for continuity and shorts.
