Solution

1. Preparation

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

2. Check Brake Fluid Level

Locate the master cylinder reservoir under the hood.
Remove the cap and check the brake fluid level.
If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).

3. Inspect ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the ABS fuse using the diagram on the cover.
Remove the fuse and inspect it for continuity; replace if blown.

4. Inspect Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the ABS wheel speed sensors near each wheel hub.
Check the wiring and connectors for damage or looseness.
Clean any debris from the sensor and its mounting area.

5. Examine ABS Control Module

Locate the ABS control module, typically found near the master cylinder.
Check for any visible signs of damage or corrosion on connectors.
If necessary, disconnect the module and inspect the connectors for corrosion.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light remains illuminated.
Perform a test drive to ensure the ABS functions properly.
