PURPOSE: To inform a driver of abnormalities with a sound in the sequence of priority when they occur at various parts of an automobile by setting the order according to the emergency degree beforehand.
CONSTITUTION: A sequence circuit 5 comprises D type flip-flops 23W26, inverters 27W32 and NAND gates 33W35. The output of various detection switches is connected to a terminal D of the D type flip-flops 23W26 while a signal drawing pulse (e) generated from a pulse generator is inputted into a terminal CK. When a signal A turns to a ground potential, a power source potential is outputted to a signal (a). Likewise, A signal B is made to correspond to a signal (b), a signal C to a signal (c), and a signal D to a signal (d). If two or more signals overlap, the priority is placed on them in the order of A, B, C, and D.
