Electronic diagnostic system

摘要

A vehicle diagnostic system suitable for coupling to a CAN bus. The system has a connector which is coupled directly to the CAN bus and an analyzer which is coupled to the connector by relatively long cables. A buffer is located in the connector to isolate the electrical load represented by the cable from the CAN bus and to communicate signals transmitted from the analyzer to the bus and received from the bus to the analyzer. Thus data can be read directly from the bus to conveniently located analysis equipment.
