ON BOARD DIAGNOSTIC (OBD) SYSTEM EC-55 [KA24DE] C D E F G H I J K L M A EC SRT Set Timing SRT is set as “CMPLT” after self-diagnosis has been performed one or more times. Completion of SRT is OK: Self-diagnosis is carried out and the result is OK. When all SRT related self-diagnoses showed OK results in a same cycle (Ignition OFF – ON – OFF), the SRT → Case 1 above When all SRT related self-diagnoses show OK results through several different cycles, the SRT will indicate → Case 2 above If one or more SRT related self-diagnoses showed NG results in 2 consecutive cycles, the SRT will also indi- → Case 3 above The previous table shows that the minimum number of cycles for setting SRT as “INCMP” is one (1) for each ● The SRT will indicate “CMPLT” at the time the respective self-diagnoses have one (1) OK result. ● The emissions inspection requires “CMPLT” of the SRT only with OK self-diagnostic results. ● When, during SRT driving pattern, 1st trip DTC (NG) is detected prior to “CMPLT” of SRT, the self-diagno- ● If the 1st trip DTC is erased, all the SRT will indicate “INCMP”.
