SRT STATUS Mode

  • For items whose SRT codes are set, “CMPLT” is displayed on the CONSULT screen; for items whose SRT codes are not set, “INCMP” is displayed.

  • “SRT STATUS” provides the presence or absence of permanent DTCs stored in control module memory.

PERMANENT DTC STATUS Mode

How to Display Permanent DTC Status

  1. Turn ignition switch OFF and wait at 10 seconds.

  2. Turn ignition switch ON.

  3. Turn ignition switch OFF and wait at 10 seconds.

  4. Turn ignition switch ON.

  5. Select “PERMANENT DTC STATUS” in “DTC & SRT CONFIRMATION” mode with CONSULT.

    NOTE:

    Permanent DTCs stored in control module memory are displayed on the CONSULT screen to show if a driving pattern required for erasing permanent DTCs is complete (CMPLT) or incomplete (INCMP).

    CAUTION:

    Since the “PERMANENT DTC STATUS” screen displays the previous trip information, repeat the following twice to update the information: “Ignition switch OFF”, “Wait for more than 10 seconds” and “Ignition switch ON”.

NOTE:

This mode is not used in regions that permanent DTCs are not regulated by law.

SRT WORK SUPPORT Mode

This mode enables a technician to drive a vehicle to set the SRT while monitoring the SRT status.
