EC-60 < FUNCTION DIAGNOSIS > [VQ40DE] ON BOARD DIAGNOSTIC (OBD) SYSTEM Permanent DTCs cannot be erased by using the Erase function of CONSULT-III or Generic Scan Tool (GST) and by disconnecting the battery to shut off power to ECM. This prevents a vehicle from passing the state emission inspection without repairing a malfunctioning part. When not passing the state emission inspection due to more than one permanent DTC, permanent DTCs should be erased, referring to this manual. NOTE: • The important items in state emission inspection are that MIL is not ON, SRT test items are set, and perma- nent DTCs are not included. • Permanent DTCs do not apply for regions that permanent DTCs are not regulated by law. Permanent DTC Item For permanent DTC items, MIL turns ON. Refer to EC-53, "Emission-related Diagnostic Information" SION-RELATED DIAGNOSTIC INFORMATION ITEMS”. Permanent DTC Set Timing The setting timing of permanent DTC is stored in ECM with the lighting of MIL when a DTC is confirmed. Permanent DTC Service Procedure How to Display Permanent DTC Status WITH CONSULT-III 1. Turn ignition switch OFF and wait at least 10 seconds. 2. Turn ignition switch ON. 3. Turn ignition switch OFF and wait at least 10 seconds. 4. Turn ignition switch ON. 5. Select “PERMANENT DTC STATUS” in “DTC & SRT CONFIRMATION” mode with CONSULT-III. NOTE: Permanent DTCs stored in ECM memory are displayed on the CONSULT-III screen to show if a driving pattern required for erasing permanent DTCs is complete (CMPLT) or incomplete (INCMP).
