Abstract

PURPOSE:To perform an easy and high-efficient diagnosis of car electric accessories, by a method wherein input and output of each electric accessory part are fetched without exerting of the influence on the operation to display them in an indicator, wherein the description, symbol, and diagram of the electric accessory are displayed, in a display panel. CONSTITUTION:In the case of electric accessory in which a plural number of loads 51 are connected in series from a power source 40 and a voltage applied to a load is low, a low-voltage is measured and displayed by a voltmeter 38 via an operational amplifier 52 combined with resistances 53 an 54 without exerting of the influence on the electric accessory which is driving an engine. In like manner as to each electric accessory as well, given input and output are fetched without exerting of the influence on the operation of the electric accessory an are displayed in a corresponding indicator, in which description,symbol, and diagram of the electric accessory are displayed, in a display panel. This enebles to perform a high-efficient diagnosis of the car electric accessory, which is driving the engine, by means of an easy operation which eliminates the need to connect the accessory to a tester.
