SRT Set Timing =NCEC0031S0308 SRT is set as “CMPLT” after self-diagnosis has been performed one or more times. Completion of SRT is done Self-diagnosis result Example Diagnosis Ignition cycle + ON , OFF + ON , OFF + ON , OFF + ON , All OK Case 1 P0400 OK (1) — (1) OK (2) — (2) P0402 OK (1) — (1) — (1) OK (2) P1402 OK (1) OK (2) — (2) — (2) SRT of EGR “CMPLT” “CMPLT” “CMPLT” “CMPLT” Case 2 P0400 OK (1) — (1) — (1) — (1) P0402 — (0) — (0) OK (1) — (1) P1402 OK (1) OK (2) — (2) — (2) SRT of EGR “INCMP” “INCMP” “CMPLT” “CMPLT” NG exists Case 3 P0400 OK OK — — P0402 — — — — P1402 NG — NG NG (Consecutive NG) (1st trip) DTC 1st trip DTC — 1st trip DTC DTC (= MIL “ON”) SRT of EGR “INCMP” “INCMP” “INCMP” “CMPLT” OK: Self-diagnosis is carried out and the result is OK. When all SRT related self-diagnoses showed OK results in a single cycle (Ignition OFF-ON-OFF), the SRT , Case 1 above When all SRT related self-diagnoses showed OK results through several different cycles, the SRT will indi- , 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 table above shows that the minimum number of cycles for setting SRT as “INCMP” is one (1) for each I The SRT will indicate “CMPLT” at the time the respective self-diagnoses have one (1) OK result. I The emissions inspection requires “CMPLT” of the SRT only with OK self-diagnosis results. I When, during SRT driving pattern, 1st trip DTC (NG) is detected prior to “CMPLT” of SRT, the self-diag- I If the 1st trip DTC is erased, all the SRT will indicate “INCMP”.
