WARNING: This page is about a different car, the 2007 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.

This procedure only needs to be carry out if the 4-wheel anti-lock brake (4WABS) hydraulic control unit (HCU) has been installed new.
- Clean all dirt from and remove the brake master cylinder filler cap, and fill the brake master cylinder reservoir with clean, specified brake fluid.
