Abstract
A control system for evaluating a brake booster system is provided. The control system includes an engine evaluation module that detects an engine off condition. A pressure evaluation module monitors hydraulic brake line pressure and detects changes in brake booster pressure during the engine off condition. A fault reporting module selectively detects a brake booster fault based on the brake line pressure and the changes in brake booster pressure.
