Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and set the parking brake.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect ABS Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the fuse for the ABS system and inspect it for continuity.
If blown, replace it with a fuse of the same amperage.

3. Check ABS Wheel Speed Sensors

Raise the vehicle using a jack and secure it with jack stands.
Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensors and connectors.
Inspect the sensors for cracks or damage; replace if necessary.

4. Inspect ABS Module Wiring

Check the wiring harness connected to the ABS module for frayed wires or corrosion.
Ensure all connectors are securely attached and free of dirt.
Repair or replace damaged wiring as needed.

5. Test ABS Module

Reconnect the battery terminal.
Use a multimeter to check the voltage at the ABS module connector.
Consult the vehicle's service manual for specific voltage and resistance specifications.
Replace the ABS module if it fails the test.

6. Clear Error Codes

Use the OBD-II scanner to clear any stored error codes once the repairs are complete.
Test drive the vehicle to ensure the ABS light remains off.
