Abstract: A system includes a processor and one or more vehicle systems, having a component in which errors can be diagnosed through electronic analysis. Also, the processor is configured to obtain instructions for running a vehicle diagnostic test, corresponding to government mandated testing, on the one or more vehicle systems, responsive to a user request. The processor is further configured to execute the test to obtain results.

Abstract: A dual battery electrical system for a vehicle having an engine comprises a primary load and a secondary load and is switchable between an ON state in which the engine is running, an OFF state in which the engine is not running, a START state in which the primary load requires power to start the engine, and a PAUSE state in which the engine is not running. A first battery powers the primary load, a second battery powers the secondary load, a battery switch is closable to connect the first battery to the second battery such that both batteries can provide power to both loads. The transition to and from the OFF state is via a user activated mechanism and transition to and from the PAUSE state is via a user-independent mechanism. A controller controls operation of the battery switch when the system enters and/or leaves the PAUSE state.

Abstract: The invention provides a dual battery electrical switchable system 2 for a vehicle having an engine. The vehicle comprises a plurality of first loads 8 and a plurality of second loads 10. The vehicle is switchable between an ON state in which the engine is running, an OFF state in which the engine is not running and a START state, in which at least one of the first loads 8 requires power. The system 2 comprises a first battery 4 arranged to provide power to the first loads 8 and a second battery 6 arranged to provide power to the second loads 10. A switch 18 is provided between the first battery 4 and the second battery 6 and control means 20 is arranged to open the switch 18 only when the vehicle is in the OFF state. A connection system 12 is also provided having a plurality of output terminals 16 for connection to the plurality of primary and secondary loads 8, 10, and two input terminals 14 for connection to the first and second batteries 4, 6 respectively.
