Abstract:
1. A debug system comprising: an electronic control unit for automobiles placed in an engine room, the electronic control unit comprising a microcomputer for controlling an operation of a control target associated with an automotive system and a transceiver circuit that is capable of communicating data with the microcomputer; an external unit for development placed in a bench room that is capable of rapidly communicating data with the transceiver circuit, the external unit used to check operations of the electronic control unit; and a wire coupling the transceiver circuit to the external unit for development, that is capable of reaching the bench room from the engine room, wherein the electronic control unit includes a power supply unit for supplying electrical power to the microcomputer, as designed with a capacity to operate the microcomputer under normal operation in the automobile, using an in-vehicle battery, the electronic control unit being insufficient to supply power to both the microprocessor and the transceiver circuit at a speed sufficient for development testing of the electronic control unit using the wire coupling to the transceiver to the external unit, and wherein the transceiver circuit operates on electrical power supplied from an external power supply unit, which differs from the power supply unit included in the electronic control unit.
