6. Repeat for all four wheels if necessary.

3. Check ABS Fuse

Sub-steps:
1. Locate the fuse box and identify the ABS fuse using the diagram on the cover.
2. Remove the fuse and visually inspect it for any signs of a break.
3. If damaged, replace it with a fuse of the same amperage.
4. Reinstall the fuse and ensure it is seated properly.

4. Inspect and Refill Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Check the fluid level; if low, add the manufacturer-recommended brake fluid.
