Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box and identify the ABS fuse and relay (refer to the owner’s manual for exact location).
Inspect the fuse and replace it if it is blown.
If the relay is faulty, remove and replace it with a new one.

4. Inspect and Repair ABS Hydraulic Control Unit

Tools Required: Socket set, torque wrench
Remove any components obstructing access to the ABS module.
Inspect the module for leaks or damage; if found, replace the module.
Reinstall any removed components and ensure they are torqued to specifications.

5. Reconnect Battery and Clear Codes

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