Abstract

In a method for implementation of a fault diagnostic system having a number of diagnostic modules and in an in-vehicle fault diagnostic system, a second diagnostic module whose diagnostic result depends on the result of the fault diagnosis of at least one first diagnostic module begins its diagnostic cycle without waiting for the diagnostic result of the first diagnostic module. The second diagnostic module writes its diagnostic result into a secondary fault memory. When the first diagnostic module has ended its diagnostic cycle without finding a fault, the diagnostic result of the second diagnostic module is transferred from the secondary fault memory into a primary fault memory.
