Abstract

The diagnostic system (10) includes a diagnostic function module (DF Module 20,20',20") for each diagnostic trouble code (DTC) or gp. of DTCs associated with a component or sub-system. The DF Module includes circuitry (22) to determine the operational status of the component or sub-system. A ranking value is generated each time a routine is performed and circuitry (23) processes and stores the latest statistics. Evaluated data is transmitted (24) indicating a fault or no-fault condition to a DF scheduler (30).
