In accordance with various advantages and disadvantages of existing design schemes for vehicle fault diagnostic instrument, the software of diagnostic instrument developed for Android mobile phone or tablet is proposed, the scheme adopts the device transferring Bluetooth to CAN for communication with vehicle. To solve the problem of upgrading of the diagnosis instrument software periodically due to updates of diagnostic database, the method of storing the database in SD card of the mobile phone or tablet is designed. Through the test and verification on electric vehicle, it is proved that the faults of vehicle can be diagnosed and analyzed by the instrument designed, comparing with existing design schemes, the new instrument features lower cost, easy to carry and software upgrade, etc.
