コン応用製品の故障診断装置。 In microcomputer application products that use ROM as a storage device for application programs and data strings, there is a ROM that stores fault diagnosis programs and data strings for fault diagnosis, and a means for connecting to the pins of an IC fixed to a printed circuit board. A diagnostic device and a means for making a ROM containing an application program fixed to a printed circuit board inaccessible to the microcomputer of the microcomputer-applied product by connecting the failure diagnostic device to the microcomputer-applied product. The ROM of the microcomputer application product is transferred to the RO containing the fault diagnosis program.
A failure diagnosis device for microcomputer-applied products, characterized in that failure analysis can be performed by executing a failure diagnosis program without replacing the M.
