Vehicle diagnostic data storing system |
摘要 |
A vehicle diagnostic information storage system includes a volatile storage device such as a backup RAM and a nonvolatile storage device such as EEPROM. If a fault occurs, a control section stores data on fault items, and input and output conditions of sensors of a vehicle control system, in the volatile storage device and updates the data in the volatile storage device during a vehicle operation. In response to a switching operation of a vehicle main switch such as a turn-on operation of an ignition switch, the control section transfers the most recent version of updated data from the volatile storage device to the nonvolatile storage device.
