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 single cycle (Ignition OFF-ON-OFF), the SRT will → Case 1 above SRT item (CONSULT-II indication) Performance Priority* Required self-diagnostic items to set the SRT to “CMPLT” Corresponding DTC No. CATALYST 2 Three way catalyst function P0420, P0430 EVAP SYSTEM 2 EVAP control system purge flow monitoring P0441 1 EVAP control system P0442 2 EVAP control system P0456 HO2S 2 Air fuel ratio (A/F) sensor 1 P0133, P0153 Heated oxygen sensor 2 P0137, P0157 Heated oxygen sensor 2 P0138, P0158 Heated oxygen sensor 2 P0139, P0159 Self-diagnosis result Example Diagnosis Ignition cycle ← ON → OFF
