Auto Scanner is a kind of auto device for reading and erasing trouble code in vehicles, usually called Auto Code Reader. Though so small, light and handy, which is dynamic and fashionable in design, competitive in price and easy to use. It is absolutely the same function as special tool of its kind and applicable to all models since 1996 with a 16-pin diagnostic socket for generic OBD2 protocols(SAE J1850 PWM, SAE J1850 VPW, ISO9 141-2). Auto Scanner is specially designed for car owners or DIY. With a Auto Scanner you may quickly find out trouble causes (troubleshooter) of electronically controlled systems on your car, by simply connecting Auto Scanner with the diagnostic socket, via reading the trouble code(DTC) shown on Auto Scanner, identifying, locating and checking out trouble causes with attached USER MANUAL. Each trouble code discovered will be displayed on Auto Scanner for 3 times,5 cycles later all the trouble codes will be automatically erased.
