Abstract
The present invention relates to a system and a method for managing time for a vehicle fault diagnostic apparatus by which temporal contradictions and errors between controllers are eliminated, and fault diagnosis is reliably performed by accurate time. To this end, the system includes a master controller (1) for transmitting a counted time as a standard time, and a plurality of controllers (11a, 11b, 11c, . . . , 11n) for determining the time relating to the fault diagnosis on the basis of the received standard time when fault data of sensors, etc., are detected.
