Many import cars the instrument warning lights will of course come on when the ignition key is turned to the ignition "on" position but then requires charging voltage to "turn off" the dash warning lights. Check the battery voltage across the battery with the engine running it should be approximately 14.7 volts if the battery is being properly charged by the alternator. There is a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect....
