Abstract
A stitch pattern sewing machine utilizes a microcomputer which operates in a stitch control mode and in a malfunction diagnosing mode. Each mode is selectively rendered effective by a changeover switch. The diagnosis of malfunction includes a series of checking steps carried out in a predetermined order. Indication means are selectively illuminated to operate in either one of the two modes in dependence upon the position of the changeover switch.
