Method for managing sequence errors, for on-board diagnosis of vehicle, involves linking coded error description with set of rules, and determining errors coded in error description or sequence errors from set of rules

摘要

The method involves detecting individual errors in system units by a diagnostic system, and transferring the individual errors to a diagnostic management system by a coded error description i.e. diagnostic trouble code (DTC). The coded error description is linked with a set of rules, where the set of rules consists of digital coded operators, a DTC range, a DTC mask, a DTC source and a DTC target. The errors coded in the error description or sequence errors are determined (10) from the set of rules, where the sequence errors are blocked for an entry into a defect memory.
