ABSTRACT:
A diagnostic method (100) with pre-assembly fault recording lock-out inhibits fault recording during assembly of a main system until the system has been determined operation at least once (116). The method will still note the detection of system failures/errors (112) by activating a warning lamp (120), but will not record these faults into memory until the system has determined that the main system has been powered up without any errors at least once (118 and 122). Thus, since these faults are not stored in memory during manufacture/assembly, the method of the present invention obviates the need for any additional assembly step(s) of erasing and/or clearing the memory, or externally controlled recording inputs for the diagnostic system.
