Solution

1. Preparation

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

2. Inspect and Replace ABS Fuse

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

3. Inspect ABS Wheel Speed Sensors

Lift the vehicle safely using jack stands.
Locate the ABS wheel speed sensors (usually near the brake rotor).
Clean the sensors and the mounting area to remove any debris or corrosion.
If the sensor shows signs of damage or wear, replace it with a new sensor.

4. Brake Fluid Inspection and Replacement

Check the brake fluid reservoir for proper fluid levels.
If the fluid is low, top it up with the recommended brake fluid type (DOT 3 or DOT 4, based on specifications).
If fluid is discolored or contaminated, drain the brake fluid and replace it with fresh fluid, bleeding the brakes to remove air bubbles.

5. Test ABS Module

Use a multimeter to check the ABS module's power and ground connections.
If the module is not receiving power, trace back to the wiring harness for any breaks or shorts and repair as necessary.
If the module is faulty, replace it according to the manufacturer's guidelines.
