Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative terminal of the battery.

2. Inspect and Replace ABS Fuse

Locate the fuse box (often under the dashboard or in the engine compartment).
Remove the cover and locate the ABS fuse.
Use a test light or multimeter to check the fuse for continuity.
If the fuse is blown, replace it with a fuse of the same amperage rating.

3. Check and Clean ABS Speed Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the ABS speed sensor.
Inspect the sensor for dirt or damage; clean with brake cleaner if necessary.
Ensure the sensor is properly seated and the wiring is intact.
If damaged, replace the ABS speed sensor with a new one.

4. Inspect ABS Module Wiring

Visually inspect wiring harnesses connected to the ABS module.
Look for frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring as necessary.

5. Test ABS Module

If all previous components are functioning, use a multimeter to test the ABS module's power and ground connections.
If the module is unresponsive, it may need to be replaced.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any ABS error codes.
Start the vehicle and observe the ABS light.
