Clean any dirt or debris from the sensors using a soft cloth or brush.
Check the wiring harness connected to each sensor for signs of wear or damage.
Reconnect the wiring after inspection.

3. Check and Test the ABS Module

Locate the ABS module; consult the service manual for specific location.
Inspect the electrical connectors for corrosion or damage.
Use a multimeter to test the voltage and ground connections to the ABS module.
Repair or replace any faulty wiring or connectors.

4. Replace Faulty Components (if needed)

If any wheel speed sensors are found to be faulty during inspection, replace them.
If the ABS module is malfunctioning, refer to the service manual for removal and installation procedures.
- Disconnect the electrical connectors.
- Remove mounting bolts using a socket set.
- Install the new ABS module and reconnect connectors.
