Vehicle diagnostic system, vehicle diagnostic method, and vehicle

摘要

Provided are a vehicle configured such that if idling does not automatically stop, an in-vehicle display will occur immediately if a malfunction is the cause, thereby enabling a driver to have peace of mind and concentrate on driving, without giving the driver an unnecessary sense of unease; a vehicle diagnostic system therefor; and a vehicle diagnostic method. The vehicle comprises an idle stop error display unit provided corresponding to a specific ECU among a plurality of ECUs, and that indicates that an idle stop malfunction has occurred, being a malfunction corresponding to a second IS malfunction code, when a malfunction has occurred within a control target range for any among the plurality of ECUs, said malfunction recording the second IS malfunction code which does not cause the operation of a warning light requesting inspection or repair of an error that has occurred inside the vehicle.

主权项

1. A vehicle diagnosing system for performing a fault diagnosis of a vehicle including an idling stop control system, the idling stop control system executing an idling stop for stopping a drive source of the vehicle from idling by cooperatively controlling a plurality of electronic control units, wherein the vehicle comprises:
a plurality of warning lamps associated with specific ones of the electronic control units, and configured to demand an inspection or repair of a failure which has occurred in the vehicle; and an idling stop controller configured to automatically execute the idling stop when a predetermined condition is satisfied; wherein when the electronic control units detect a fault in target ranges controlled thereby, the electronic control units record fault codes; the fault codes include idling stop fault codes defined as inhibiting the idling stop of the drive source, and non-idling stop fault codes not defined as inhibiting the idling stop; the idling stop fault codes include first idling stop fault codes defined as energizing the warning lamps and second idling stop fault codes defined as not being serious enough to energize the warning lamps; and the vehicle further comprises an idling stop failure indicator configured to indicate an idling stop fault corresponding to one of the second idling stop fault codes instead of the plurality of warning lamps, when the idling stop fault which records the one of the second idling stop fault codes in any of the electronic control units has occurred in a target range controlled thereby.
