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.

2. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris covering the sensors with a clean cloth.
Check the wiring and connectors for damage; repair or replace as needed.

3. Check ABS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the ABS fuse using the fuse diagram.
Remove the fuse and check for continuity with a multimeter; replace it if blown.

4. Verify Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top it off with the recommended brake fluid type (DOT 3 or DOT 4).
Inspect the reservoir for leaks and replace if necessary.

5. Test ABS Module

Reconnect the battery terminal.
Use the OBD-II scanner to clear any stored codes.
Start the vehicle and check if the ABS light remains illuminated.
If the light stays on, further testing of the ABS module may be necessary, which could involve professional diagnostic tools.
