<p>A car diagnosis method, and apparatus therefor, which liberate workers from troubles with the sequence and timing of various operations to be carried out by the workers for each diagnostic item. A car condition detection portion (223) communicates with an ECU (1) and cyclically detects the actual condition of each portion of a car. A selection portion (222) selects a scheduled condition to be exhibited by each portion of the car, whose actual condition is cyclically detected, from a reference data memory area (73) of a ROM card (7) or from a non-reference data memory area (74). A comparison portion (224) compares the actual condition of each portion of the car cyclically detected by the car condition detection portion (223) with the scheduled condition selected by the selection portion (222), diagnoses that the diagnostic item is good (acceptable) when they have a predetermined relation, and displays the result on a display portion (27).</p> |
