Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery's negative terminal to prevent electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box and identify the ABS fuse.
Use a fuse puller or pliers to remove the ABS fuse.
Inspect the fuse for continuity; replace it if blown with a fuse of the same amperage.

3. Check and Top Off Brake Fluid

Locate the brake fluid reservoir.
Inspect the fluid level; if low, clean the reservoir cap and add the appropriate type of brake fluid (DOT 3 or DOT 4).
Reconnect the cap securely to prevent contamination.

4. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Locate the ABS wheel speed sensors at each wheel hub.
Disconnect the sensor connector and inspect the wire harness for damage.
Clean the sensor and mounting area; replace the sensor if damaged or corroded.

5. Replace the ABS Control Module (if necessary)

If other components are functioning and the light remains on, consider replacing the ABS control module.
Disconnect the battery and remove the necessary components to access the module.
Remove the old control module, install the new one, and reconnect all electrical connectors.
Reassemble components and reconnect the battery.
