Abstract:
A method for implementing a fault diagnostic system having a number of diagnostic modules that monitor sub-systems during a diagnostic cycle and provide a diagnostic result, said method comprising the steps of:starting a diagnostic cycle of a second diagnostic module without waiting for a diagnostic result of a first diagnostic module, said second diagnostic module having a diagnostic result dependent on a result of a fault diagnosis of at least one first diagnostic module; writing said diagnostic result of said second diagnostic module into a secondary fault memory when said diagnostic result of said first diagnostic module is not yet provided after an end of said diagnostic cycle of said second diagnostic module; and writing said diagnostic result of said second diagnostic module into a primary fault memory when said first diagnostic module has not diagnosed a fault after an end of a diagnostic cycle of said first diagnostic module, said primary fault memory having entries for judging functionability of said sub-systems.
