Self-diagnosis Starting Methods If OFF switch is continuously pressed for 5 seconds or more within 10 seconds after ignition switch is turned ON from OFF, the self-diagnosis mode shall be started. 13-2-2. Self-diagnosis Quitting Methods When AUTO switch is pressed or ignition switch is turned off during self-diagnosis, the self-diagnosis shall be released. 1) LCD segment 2) LED 2-1) DEF 2-2) RearDEF 2-3) A/C 17 of 29 1-1) FAN 1-2) MODE 1-3) Set temperature 1-4) ?C 2-4) RECIRC 1-5) Human 2-5)Ambient Temperature 1-6) －　(minus) 2-6)AUTO *The check of the input data of each sensor is executed to detect short-circuits failure or open-circuit failure. *An output signal shall be outputed to each actuator to judge a normal status, short, or open-circuit failure. *The number of the failure sensor is indicated. The display blinking order shall be shown in the following table. *Processing at reset operation is executed by the DEF switch operation (1) Initial setting 1) When STEP3 is selected, “3” shall be displayed on the set temperature indicator for 1 second. 2) In this period, the actuator shall be checked. (2) Actuator failure display 1) For a normal status, 30 shall be displayed on the set temperature indicator. 2-1) The target cycle of blinking shall be ON: 0.7 sec and OFF: 0.2 sec. 2) For a failure, the corresponding number of the actuator terminal shall blink on the set temperature indicator. 2-2) When multiple failures occur, each sensor number shall blink 2 times according to the following order. 2-1) The target cycle of blinking shall be ON: 0.7 sec and OFF: 0.2 sec. 2-3) To distinguish a short-circuit failure from an open-circuit failure, the sensor number shall blink on the 2-2) When multiple failures occur, each number of the actua
