Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Clean ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Remove any dirt or debris around the sensors using a clean cloth.
If necessary, unbolt the sensor using a socket set and inspect for damage. Replace if faulty.

3. Check and Replace Brake Fluid

Remove the brake fluid reservoir cap and check the fluid level.
If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If the fluid is contaminated, perform a brake fluid flush to replace it entirely.

4. Test and Replace ABS Fuse

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

5. Reconnect Battery and Reset ABS System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any ABS error codes and reset the system.
