Abstract:
     This invention provides an on-vehicle electronic controller improved in safety so as not to be unexpectedly activated by an alarm timer circuit part. The on-vehicle electronic controller 100a is constituted of a main control circuit part 110a and an alarm timer circuit part 120a. When a pulse period of a watch dog clear signal WD1 which a main CPU 111a generates is normal, closed circuit function retaining a closing motion element 104a by an output permission signal OUTE which a watch dog timer circuit 119 generates and then, alarm output is released by forced OFF command from the main CPU111a. If the alarm output is nor released, the alarm timer circuit part 120a self-resets the alarm output after a specific time.
